TAVIGER : Intérêt d’une expertise coordonnée gériatrique et cardiologique dans le bilan d’éligibilité des patients âgés à un remplacement valvulaire aortique par voie percutanée

BackgroundTranscatheter aortic valve implantation (TAVI) is the gold standard treatment for aortic stenosis in the elderly. Pre-identification of patients likely to benefit from this procedure remains crucial. A standardised geriatric assessment is used to identify the major geriatric syndromes likely to influence postoperative outcomes. ObjectiveTo identify factors associated with lack of TAVI management and to compare one-year survival in TAVI vs. non-TAVI patients. MethodsRetrospective study, between 2016 and 2020, at the Arras hospital. Patients aged 70 years and older with symptomatic severe aortic stenosis who had undergone geriatric assessment were included. ResultsOne hundred and ninety-two (192) patients, mean age 82.3 years. The 1-year mortality rate was 18% in the TAVI group and 44% in the non-TAVI group (p < 0.001).Parameters associated with no TAVI were Euroscore (ESL) 1 (19.6 ± 10.9 vs. 23.2 ± 13.5, p = 0.020), malnutrition (14% vs. 35%, p = 0.004), walking speed < 0.8 m/s (39% vs. 75%, p = 0.001), Activities of Daily Life (ADL) score (5.4 ± 1 vs. 4.2 ± 1. 6, p < 0. 001) and Instrumental Activities of Daily Life (IADL) score (2.6 ± 1.2 vs. 1.8 ± 1.4, p = 0.002), Mini Geriatric Depression Scale (mini GDS) ≥ 1 (16% vs. 38%, p = 0.045), Mini Mental State Examination (MMSE) score (25.1 ± 3.5 vs. 21.6 ± 4.3 < 0.001). ConclusionsGeriatric syndromes are important determinants of TAVI candidacy. Cardiological surgical risk scores are not effective in discriminating between patients. Coordinated assessment may optimise selection. Therefore, geriatric assessment should be systematically performed as part of the pre-TAVI evaluation.

Association of TRI-SCORE with clinical outcomes after percutaneous tricuspid annuloplasty

Abstract Background Significant tricuspid regurgitation (TR) has been associated with excess mortality and heart failure. Functional TR is associated to progressive right ventricular remodeling and dysfunction, leading to comorbidities which elevate the perioperative mortality of isolated tricuspid regurgitation surgery, with an in-hospital mortality between 6-10% according to series. Transcatheter tricuspid annuloplasty is a promising therapeutic alternative in patients with high surgical risk. Appropriate risk stratification and patient selection is essential to ensure benefits of this intervention. European System for Cardiac Operative Risk Evaluation (EUROSCORE) II and the Society of Thoracic Surgeons (STS) score are widely spread in-hospital mortality risk scores in valvular surgery. TRI-SCORE is focused on isolated TR surgery; nevertheless, application of these scores to transcatheter annuloplasty has not been specifically studied yet. Purpose To analyze the utility of surgical scores (EUROSCORE-II, STS and TRISCORE) to predict all-cause mortality in patients undergoing transcatheter tricuspid annuloplasty. Methods A cohort of 49 patients with significant TR was followed up prospectively after the transcatheter tricuspid annuloplasty with Cardioband between 2019 and January 2024 (mean follow-up 18,43 ± 10,95 months). Every score was evaluated in all patients. According to the TRI-SCORE –– 6 points was the 75-percentile and taken as cutoff value –– we divided the cohort in two groups: a low score group (≤6 points) and a high score group (&amp;gt;6 points). Survival was analyzed in the whole cohort and in both subgroups. The curves are depicted using Kaplan-Meier method and were compared using log rank test. Results The study included 49 patients, with mean age of 77,6 ± 7,67 years, 77,6% being women. All the patients had a secondary etiology of TR and 46,9% massive or torrential TR before the intervention. 49% had previous left heart surgery. The median surgical risk values are represented in Table 1. All-cause mortality during follow-up occurred in 9 patients (18,3%). Survival analysis based on EUROSCORE II and STS did not find statically significant association (Table 1). TRI-SCORE had a hazard ratio (HR) of 1,59, also without statically significant association (CI 0.93 – 2.71; p 0.089). Survival analysis in high score group found an increased risk of all-cause mortality (HR 8.5; p 0.025). According to our findings TRI-SCORE &amp;gt; 6 before the procedure confers significant risk of all-cause death (log rank p = 0.009). Figure 1. Conclusions Transcatheter tricuspid annuloplasty is a promising therapy for patients with significant TR regurgitation who are at high surgical risk. According to our findings, TRI-SCORE is an appropriate scoring model to predict all-cause mortality after percutaneous annuloplasty with band. It is not so for other surgical risk scores. Extended follow-up and broader experienced are needed to corroborate these results.Surgical scores: median and mortalitySurvival curves TRI-SCORE

The CT-derived fat-free muscle fraction is associated with inflammation and predicts outcome in patients with aortic stenosis undergoing TAVR

Abstract Background The ESC guidelines underscore the importance of objective risk stratification in making patient-centered decision for valve interventions. However, they primarily rely on surgical risk scores, not considering essential factors such as frailty. Computed tomography (CT) is a routine part of the pre-interventional workup in patients undergoing TAVR and allows for body composition analysis, including the assessment of fat-free muscle fraction (FFMF) as an indicator of muscle quality. Purpose This study aimed to assess the correlation between FFMF and both inflammation and endocrine disorders, and to investigate the predictive value of FFMF in patients with aortic stenosis undergoing TAVR. Methods The study included 789 patients undergoing TAVR between 2017 and 2019. Evaluations involved CT scans to assess body composition. Using densitometric thresholds, the skeletal muscle area at L3/L4 level was separated into fatty and lean muscle to calculate the FFMF. The cohort was divided into tertiles of high, medium, and low FFMF, Figure 1. Results The study population was 45.5% female with a mean age of 81.2±6.0 years. Overall, 261 (33.1%) patients had a high FFMF, 293 (37.1%) had a medium FFMF, and 235 (29.8%) had a low FFMF. Patients with a low FFMF were older (82.3±5.9 vs 81.6±5.6 vs 79.8±6.2 years, p&amp;lt;0.01) and had higher rates of atrial fibrillation (52 vs 43 vs 37%, p&amp;lt;0.01), compared to those with a medium and high FFMF. Regarding body composition, low FFMF patients had a higher percentage of body fat (28.7±11.2 vs 26.8±9.1 vs 24.2±9.6%, p=0.01) and a lower percentage of body muscle (30.9±5.3 vs 31.3±4.2 vs 32.7±4.4%, p=0.03). Moreover, a low FFMF was associated with inflammation, as indicated by increased levels of C-reactive protein (6.3 vs 4.2 vs 3.1 mg/l, p&amp;lt;0.01) and procalcitonin (0.06 vs 0.05 vs 0.05 µg/l, p=0.01). Endocrinological assessment revealed lower levels of estradiol (6.8 vs 14.7 vs 15.0 pg/ml, p=0.02) and testosterone (0.18 vs 0.48 vs 2.35 ng/ml, p&amp;lt;0.01) as well as higher levels of cortisol (8.9 vs 7.7 vs 7.6μg/dl, p=0.05) in low FFMF patients. Regarding clinical outcomes, low FFMF was associated with increased one-year mortality (23.4%) compared to medium (11.6%) or low FFMF (3.8%, p&amp;lt;0.01), Figure 2A. This difference persisted over five years (p&amp;lt;0.01), Figure 2B. ROC curve analysis showed that FFMF had the strongest association with one-year mortality (AUC 0.75, p&amp;lt;0.01) and was superior to the STS-PROM (AUC 0.65) and EuroSCORE II (AUC 0.64). Multivariate analysis revealed that low FFMF was independently associated with mortality following TAVR (OR: 3.19 [CI: 1.64 – 6.22], p&amp;lt;0.01). Conclusion The CT-derived FFMF is associated with inflammation and endocrinological disorder in patients undergoing TAVR. Importantly, a low FFMF is a strong and independent predictor of dismal outcomes. FFMF assessment can seamlessly integrate into routine pre-interventional CTs, offering a promising objective parameter for outcome prediction.

Myocardial remodelling in bicuspid aortic valve associated severe aortic stenosis and reverse remodelling after aortic valve replacement

Abstract Background Bicuspid aortic valve (BAV) is a common congenital heart disease and a major risk factor for aortic stenosis (AS). Myocardial remodelling response to AS plays an important prognostic role1. Cardiovascular magnetic resonance (CMR) can evaluate myocardial structure, function and perfusion in AS. Phosphorus magnetic resonance spectroscopy (31P-MRS) can also assess myocardial energetic consequences of AS2. Purpose Assess differences in myocardial remodelling between tricuspid aortic valve (TAV) and BAV-associated severe-AS, and their recovery 6 months post aortic valve replacement (AVR). Methods Eighty severe-AS patients (70[69-72]years) undergoing AVR (40 TAV, 40 BAV) and 21 demographically-matched controls were recruited. AS groups were matched for demographics, AS severity, surgical risk scores and comorbidities. One month before and 6 months post-AVR, patients underwent CMR and 31P-MRS for measuring left ventricular (LV) mass, concentricity-index (LV mass to LV end-diastolic volume ratio), global longitudinal shortening (GLS), rest and adenosine-stress myocardial blood flow (MBF), myocardial perfusion reserve (MPR) and energetics-index phosphocreatine to ATP ratio (PCr/ATP). Results Pre-AVR, there was no significant differences between the three cohorts when assessing LV ejection fraction, indexed LV end-diastolic volume and indexed end-systolic volume. Pre-AVR, both AS groups showed higher LV-concentricity (controls:0.53[0.51,0.60], TAV:0.95[0.82,1.07], BAV:0.92[0.82,1.08]g/ml;P&amp;lt;0.0001), higher mass-index (controls:45[39,50], TAV:73[67,78], BAV:74[68,80]g/m2;P&amp;lt;0.0001), impaired GLS (controls:18.8[16.5,19.5], TAV:12.6[11.3,13.9], BAV:13.6[10.9,16.6]%;P&amp;lt;0.0001). Reductions in both AS groups were also seen in PCr/ATP (controls:2.19[1.85,2.63], TAV:1.64[1.39,1.85], BAV:1.85[1.60,2.10];P=0.0004), stress-MBF (controls:2.16[1.88,2.27], TAV:1.35 [1.16,1.56], BAV:1.36[1.00,1.66]ml/min/g;P&amp;lt;0.0001), and MPR (controls:3.38[2.65,3.92], TAV:2.04 [1.78,2.46], BAV:1.83[1.58,2.78]ml/min/g;P&amp;lt;0.0001) against controls, with no significant differences between TAV and BAV. No significant difference was seen in the proportion of patients with TAV and BAV undergoing transcatheter or surgical AVR (table1). Post-AVR, the TAV and BAV groups experienced similar patterns of reverse LV-remodelling, with no significant differences in LV-concentricity (TAV:0.86[0.71,0.98], BAV:0.81[0.65,0.96];P=0.41), LV-mass-index (TAV:60[54,65], BAV:61[55,66];P=0.81), GLS (TAV 15.4[13.6,17.9], BAV 16.3[12.8,18.1];P=0.82. Perfusion and cardiac energetic improvements were also similar between the AS cohorts: PCr/ATP (TAV:1.96[1.68,2.26], BAV:1.96[1.79,2.13];P=0.91), stress-MBF (TAV:1.63[1.37,1.97], BAV:1.56[1.25,1.97];P=0.86), and MPR (TAV:2.64[1.91,3.26], BAV:2.55[2.07,3.28];P=0.70). Conclusions Patients with severe AS irrespective of BAV or TAV morphology, show a similar myocardial phenotype pre-AVR, with similar magnitudes of reverse remodelling post-AVR.

Clinical outcomes according to clinical and surgical risk scores for tricuspid regurgitation

Abstract Background TRIO score, the clinical risk score in significant tricuspid regurgitation (TR), and TRI-SCORE, the surgical mortality risk for tricuspid valve (TV) surgery, have been proposed. We aimed to investigate the correlation and distribution of two risk scores, and to define the clinical benefit of TV surgery in patients with low or intermediate TRIO score and TRI-SCORE. Methods In a total of 10,054 patients diagnosed with moderate to severe TR between January 2008 to December 2020, TRIO score and TRI-SCORE were stratified into low, intermediate, and high-risk groups. Patients of all etiologies of TR were included and patients who underwent prior tricuspid valve surgery were excluded. The clinical outcome was all-cause death. Results TRI-SCORE and TRIO scores were moderately correlated (r =0.39, p&amp;lt;0.001). 9,104 (90.6%) patients (age 67 ± 14 years, 42% male) had low or intermediate TRI and TRIO score. During 12.6 ± 10.1 years, 885 (9.7%) underwent TV surgery and 1,268 (13.9%) experienced clinical outcomes. Kaplan-Meier analysis revealed significant differences in clinical outcomes according to TV surgery in both low and intermediate TRIO score patients (log-rank, p&amp;lt;0.001) and sub-analyzed them according to the TRI-SCORE group (Figure). In multivariable Cox regression analysis, TV surgery (HR 0.37, 95% CI 0.28-0.49, p&amp;lt;0.001) were significantly associated with clinical outcomes after adjusting confounding factors. Conclusions TV surgery is clinically beneficial in moderate to severe TR patients with a low or intermediate TRIO score and TRI-SCORE.

Long-term outcomes of left bundle branch area pacing compared with right ventricular pacing in TAVI patients

BackgroundNew-onset permanent pacemaker implantation (PPMI) is still a common complication after transcatheter aortic valve implantation (TAVI) with adverse clinical outcomes. ObjectiveThe purpose of this study was to investigate whether left bundle branch area pacing (LBBAP) improves long-term clinical results compared with traditional right ventricular pacing (RVP) in patients requiring PPMI after TAVI. MethodsA total of 237 consecutive patients undergoing RVP (N = 117) or LBBAP (N = 120) after TAVI were retrospectively included. Long-term outcomes, including all-cause death, heart failure rehospitalization (HFH), and left ventricular ejection fraction (LVEF) change compared to baseline, were obtained until 5 years post-TAVI. ResultsThe mean age of the overall population was 74 years, with a mean surgical risk score of 4.4%. The paced QRS duration was significantly longer in the RVP group compared with the LBBAP group (151 ± 18 vs 122 ± 12 ms; P < .001). No difference was found between the 2 groups in all-cause death (13.7% vs 13.3%; adjusted hazard ratio [HR], 0.76; 95% confidence interval [CI], 0.37–1.58; P = .466) or the composite endpoint of death and HFH (29.9% vs 19.2%; adjusted HR, 1.22; 95% CI, 0.70–2.13; P = .476); however, the risk of HFH was significantly higher in the RVP group at 5 years after TAVI (21.4% vs 7.5%; adjusted HR, 2.26; 95% CI, 1.01–5.08; P = .048). There was greater improvement of LVEF over time in the LBBAP group (P = .046 for LVEF changes over time between groups). ConclusionsLBBAP improved long-term clinical outcomes compared with RVP in patients undergoing PPMI after TAVI in terms of less HFH and better LVEF improvement.

Treatment Adherence Rates and Long-Term Mortality in a Quaternary Multidisciplinary Heart Team: An Observational Cohort.

A multidisciplinary heart team (HT) approach to patients with complex coronary artery disease has a class IB recommendation, yet there are limited data on adherence to HT treatment recommendations and long-term clinical follow-up. The objective of this study was to assess adherence rates to HT recommendations and assess long-term mortality rates among patients with complex CAD. Six hundred eighty-four sequential HT cases for complex coronary artery disease from January 2015 to May 2017 were reviewed. After excluding cases with significant comorbid valve disease, baseline characteristics were compared based on HT treatment recommendations: optimal medical therapy, percutaneous coronary intervention, and coronary artery bypass grafting. Adherence rates were manually extracted, and 5-year mortality rates were obtained from the Michigan Death Registry. Seventy-two percent of 405 included patients were men (mean age 66±11 years), with high rates of medical comorbidities. Estimated surgical risk scores were lowest in the coronary artery bypass grafting group. Optimal medical therapy was recommended in 138 patients (34%), percutaneous coronary intervention in 95 (23%), and coronary artery bypass grafting in 172 (42%). Adherence to HT recommendations across groups was high (96%) and did not differ between treatment groups. Over 5 years of follow-up, there were 119 deaths, resulting in a cumulative mortality rate of 29%. In the largest HT cohort in the United States to date, high rates of adherence to HT recommendations were observed among high-risk patients with coronary artery disease. High rates of adherence to HT recommendations were observed irrespective of treatment group recommendation, suggesting that HT recommendations were individualized and acceptable to both patients and physicians alike.

Comparison of clinical and echocardiographic outcomes between mini-thoracotomy transatrial LuX-Valve transcatheter and surgical tricuspid valve replacement.

Transcatheter tricuspid valve replacement (TTVR) has recently emerged as a novel therapeutic approach for managing severe tricuspid regurgitation (TR). However, surgical tricuspid valve replacement (STVR) continues to be the predominant treatment modality. There are limited comparative data on both procedures. This study aimed to compare clinical and echocardiographic outcomes between patients who underwent mini-thoracotomy transatrial LuX-Valve TTVR and those who underwent STVR. This study prospectively collected patients with severe TR who underwent TTVR (n = 29) or isolated STVR (n = 59) at Wuhan Union Hospital from 2019 to 2022. All TTVR patients received the LuX-Valve via a mini-thoracotomy and transatrial approach. The clinical and echocardiographic outcomes were compared at 30-day and one-year follow-ups. At baseline, patients with LuX-Valve TTVR had higher surgical risk scores and a greater proportion of right ventricular dysfunction compared with STVR. In the early postoperative period, the STVR group had a greater decrease in right ventricular function. Hospital length of stay (LOS), intensive care unit LOS, total procedure time, and tracheal intubation time were shorter in the TTVR than in the STVR group. The incidence of postoperative paravalvular leaks was higher among patients who underwent TTVR. Compared to the STVR group, the pacemaker implantation rate was lower in the TTVR group. During follow-up, the peak tricuspid valve velocity and mean gradient in the TTVR group were consistently lower than those in the STVR group. There was similar mortality between TTVR and STVR at 30-day and one-year follow-ups. The mini-thoracotomy transatria LuX-Valve TTVR has a higher incidence of paravalvular leaks and a lower rate of pacemaker implantation than STVR, with similar 30-day and one-year mortality rates. In some respects, mini-thoracotomy transatrial LuX-Valve TTVR may be a feasible and safe treatment option for specific populations, or it could potentially serve as an alternative therapy to supplement conventional STVR. Further follow-up is required to assess differences in long-term clinical outcomes and valve durability.

Evaluation of Stenotrophomonas Maltophilia Bloodstream Infections in a Tertiary Pediatric Cardiovascular Surgery Intensive Care Unit in Turkey

Background: Stenotrophomonas maltophilia poses a significant challenge as a drug-resistant opportunistic bacterium, particularly in ICU settings. However, its impact on pediatric ICU patients, especially those undergoing cardiovascular surgery, are scarce. Therefore, we aimed to analyze the factors behind S. maltophilia bloodstream infections (BSI) in our tertiary pediatric cardiovascular surgery ICU by evaluating the 2-year data. Methods: In this retrospective study, we analyzed data of 11 (mean age 20.3±17.6 months) and 18 cases (mean age 22.4±18.5 months) diagnosed with S. maltophilia BSI out of 635 and 685 children who underwent cardiovascular surgery from March 2021 to February 2022, and March 2022 to February 2023, respectively. Factors including age, gender, cardiac pathologies, surgical risk scores, duration of extracorporeal membrane oxygenation (ECMO) and mechanical ventilation, length of ICU stay, and use of broad-spectrum antibiotics were compared. Results: The incidence of S. maltophilia BSI increased by 50.5% in 2022-2023 compared to the previous year. While no significant differences were noted in age, gender, or surgical frequency, notable distinctions emerged in ECMO and mechanical ventilation durations, ICU length of stay, and broad-spectrum antibiotic usage (p values&lt;0.05). Conclusion: Prolonged ECMO and mechanical ventilation, along with extended ICU stays and broad-spectrum antibiotic administration following highrisk cardiac surgeries, emerged as significant contributors to S. maltophilia BSI in our ICU. This underscores the necessity for a comprehensive approach encompassing infection control protocols, prudent antimicrobial utilization, and strategies to minimize invasive procedures. Such a multifaceted approach is paramount in mitigating the prevalence of S. maltophilia BSI, especially in high-risk ICU environments.

Transcatheter Aortic Valve Replacement–Associated Prosthetic Valve Endocarditis Due to Pseudomonas aeruginosa

Abstract Introduction In patients unsuitable for surgical aortic valve replacement (SAVR), transcatheter aortic valve replacement (TAVR) is an alternative treatment modality for severe aortic stenosis. Prosthetic valve endocarditis (PVE) is uncommon after TAVR, and TAVR-PVE due to Pseudomonas aeruginosa is rare. We report a patient with P. aeruginosa TAVR-PVE and review the literature on the topic. Case A 70-year-old woman with history of atrial fibrillation and severe aortic stenosis status post TAVR 4 months previously presented with a third episode of P. aeruginosa bacteremia. She initially developed P. aeruginosa bacteremia 18 days after TAVR. She failed two 6-week courses of intravenous cefepime treatment and then developed P. aeruginosa breakthrough bacteremia while on her third course of intravenous cefepime. Surgical intervention was declined by the patient. Two prior transesophageal echocardiograms (TEEs) were negative for vegetation, but after her breakthrough bacteremia, a repeat TEE showed a 1.5 × 0.8-cm vegetation on the aortic valve. Patient and family declined further therapy and transitioned to hospice and died 5 days later. Discussion This is the sixth reported case of P. aeruginosa TAVR-PVE. Enterococcus faecalis, coagulase-negative Staphylococcus and Staphylococcus aureus, and streptococci are the most common etiologic agents causing TAVR-PVE. Diagnosis is difficult, and TEE may be nondiagnostic. Of the 6 reported cases, the only 2 to survive underwent SAVR despite high Society of Thoracic Surgery risk calculator scores. Conclusion TAVR-PVE due to P. aeruginosa is rare and will likely not be cured by medical therapy alone. Surgical intervention with SAVR should be considered as the only available curative therapy despite high Society of Thoracic Surgery surgical risk scores.

Integration of a machine learning model-generated surgical risk score into the EHR and preoperative workflow.

11163 Background: We previously developed a machine learning model (MLM) that accurately predicts postoperative complications (POC) for cancer inpatients. As laborious manual entry of patient data is a barrier for risk calculator use, and risk constantly changes depending on clinical status, we sought to integrate our MLM into the electronic health record (EHR) and preoperative workflow as a readily available surgical risk score (SRS) that is generated using real-time data. Here, we report on the integration process and survey results regarding its functionality and impact on patient care. Methods: A MLM that predicts severe POC (CD Grade ≥3) for cancer inpatients undergoing same-hospitalization operations was previously developed using EHR data. To integrate our MLM into the Epic EHR, we developed a real-time infrastructure (RTI) using the cloud-based platform Azure. EHR data is inputted to RTI and processed in real-time to generate model outputs. These outputs are then sent back to the EHR through the Epic Cognitive Computing Platform to generate each patient’s specific SRS. The SRS is dichotomized as “high” or “low” risk based upon a previously determined threshold and is displayed as a “Best Practice Advisory (BPA)” when a surgical case request is entered. In addition to the automated BPA, the SRS is sent to the primary surgeon as an InBasket Case Message. To elicit feedback of our EHR-integrated SRS, a survey was distributed to surgical providers at our institution. Results: After integration of our MLM into the EHR preoperative workflow, 185 surgeries were completed between November 16, 2021 to July 31, 2023. The 30-day severe POC rate was 27.6%, and our MLM had precision of 44.7% and recall of 74.5%, resulting in AUROC of 0.78 and AUPRC of 0.53. 35 surgical providers (40% primary surgeons, 34% surgical fellows, 26% advanced practice providers) from the divisions of surgical oncology, colorectal surgery, and gynecologic oncology completed our survey in July 2022 and July 2023. 28 (80%) of providers stated that they have interacted with the SRS through either BPA or InBasket Case Messages. Of these providers, 21 (75%) strongly agreed or agreed that the SRS was visible at appropriate times, and 18 (64%) strongly agreed or agreed that the SRS contains relevant information to assess surgical risk. 8 (29%) strongly agreed or agreed that the SRS was used to facilitate preoperative discussion. The 2023 survey additionally asked whether the SRS impacted the decision to operate; among providers who had interacted with the SRS, 4 (36%) strongly agreed or agreed with this statement. Conclusions: Integration of a real-time, MLM-generated SRS into the EHR and preoperative workflow can be successfully performed. While our integrated SRS is visible to surgeons and contains risk assessment felt relevant to the operation, the impact of the SRS on clinical care and decision making remains unclear.

Exploring the relationship between language, postoperative pain, and opioid use

Racial and ethnic disparities in pain management are well documented. Differences in pain assessment and management by language have not been studied in the postoperative setting in gynecologic surgery. This study aimed to investigate the association between language and immediate postoperative pain management by comparing pain assessments and perioperative opioid use in non-English speakers and English speakers. This was a retrospective cohort study comparing perioperative outcomes between non-English-speaking patients and English-speaking patients who had undergone a gynecologic oncology open surgery between July 2012 and December 2020. The primary language was extracted from the electronic medical record. Opioid use is expressed in oral morphine equivalents. Proportions are compared using chi-square tests, and mean values are compared using 2-sample t tests. Although interpreter services are widely available in our institution, the use of interpreters for any given inpatient-provider interaction is not documented. Between 2012 and 2020, 1203 gynecologic oncology patients underwent open surgery, of whom 181 (15.1%) were non-English speakers and 1018 (84.9%) were English speakers. There was no difference between the 2 cohorts concerning body mass index, surgical risk score, or preoperative opioid use. Compared with the English-speaking group, the non-English-speaking group was younger (57 vs 54 years old, respectively; P<.01) and had lower rates of depression (26% vs 14%, respectively; P<.01) and chronic pain (13% vs 6%, respectively; P<.01). Although non-English-speaking patients had higher rates of hysterectomy than English-speaking patients (80% vs 72%, respectively; P=.03), there was no difference in the rates of bowel resections, adnexal surgeries, lengths of surgery, intraoperative oral morphine equivalents administered, blood loss, use of opioid-sparing modalities, lengths of hospital stay, or intensive care unit admissions. In the postoperative period, compared with English-speaking patients, non-English-speaking patients received fewer oral morphine equivalents per day (31.7 vs 43.9 oral morphine equivalents, respectively; P<.01) and had their pain assessed less frequently (7.7 vs 8.8 checks per day, respectively; P<.01) postoperatively. English-speaking patients received a median of 19.5 more units of oral morphine equivalents daily in the hospital and 205.1 more units of oral morphine equivalents at the time of discharge (P=.02 and P=.04, respectively) than non-English-speaking patients. When controlling for differences between groups and several factors that may influence oral morphine equivalent use, English-speaking patients received a median of 15.9 more units of oral morphine equivalents daily in the hospital cohort and similar oral morphine equivalents at the time of discharge compared with non-English-speaking patients. Patients who do not speak English may be at risk of undertreated pain in the immediate postoperative setting. Language barrier, frequency of pain assessments, and provider bias may perpetuate disparity in pain management. Based on this study's findings, we advocate for the use of regular verbal pain assessments with language-concordant staff or medical interpreters for all postoperative patients.

Impact of preoperative persistent or permanent atrial fibrillation on inhospital mortality after coronary artery bypass graft surgery

Introduction: Atrial fibrillation (AF) is an arrhythmia that has a well-established impact on cardiovascular and cerebrovascular morbidity and mortality. However, the role of this arrhythmia plays on surgical risk remains uncertain. Objective: to evaluate the impact of preoperative persistent or permanent AF on in-hospital mortality after isolated coronary artery bypass graft surgery (CABG). Methods: prospective cohort with 2,377 patients submitted to isolated CABG between January 2014 and December 2021. Sixty-two variables, including baseline factors, operative characteristics, and outcomes, were analyzed. Patients were divided into two study groups: No preoperative AF (n=2,287) and preoperative persistent or permanent AF (N=90). The comparison between the groups was performed initially by descriptive and univariate analysis. Subsequently, the analysis of mortality predictors was performed using binary logistic regression - multivariate adjusted analysis. Results: patients with preoperative AF were older, had a higher prevalence of pulmonary hypertension and anemia, had lower ejection fraction and had higher surgical risk scores when compared with patients with no history of atrial fibrillation. The in-hospital death was more frequent in patients with a history of AF (3.2% vs 8.9%, P=0.010). Through the multivariate analysis, it was possible to verify that preoperative AF is independently associated with the occurrence of in-hospital mortality after CABG (OR 2.68; 95% CI 1.21-5.94, P=0.015). Conclusion: Preoperative persistent or permanent AF has been shown to have a significant impact on in-hospital mortality rates after CABG even after adjusted multivariate analysis, being an independent risk predictor for the occurrence of postoperative death.

Percutaneous aortic valve replacement: outcome of patients evaluated by EMG at Toulouse University Hospital preprocedure

Transcatheter Aortic Valve Implantation has become the preferred method of aortic valve replacement in the elderly. Preoperative standardized geriatric assessment (SGA) helps guide the decision to proceed, taking into account geriatric parameters not targeted by surgical risk scores. This is a descriptive, retrospective study of patients who underwent EGS at the Toulouse University Hospital, analyzing their length of stay and postoperative care pathway.

Poor olfaction prior to cardiac surgery: Association with cognition, plasma neurofilament light, and post-operative delirium.

Post-operative delirium (POD) affects up to 50% of cardiac surgery patients, with higher incidence in older adults. There is increasing need for screening tools that identify individuals most vulnerable to POD. Here, we examined the relationship between pre-operative olfaction and both incident POD and POD severity in patients undergoing cardiac surgery. We also examined cross-sectional relationships between baseline olfaction, cognition, and plasma neurofilament light (NfL). Individuals undergoing cardiac surgery (n=189; mean age=70years; 75% men) were enrolled in a clinical trial of cerebral autoregulation monitoring. At baseline, odor identification performance (Brief Smell Identification Test), cognitive performance, and plasma concentrations of NfL levels (Simoa™ NF-Light Assay) were measured. Delirium was assessed with the Confusion Assessment Method (CAM) or CAM-ICU, and delirium severity was assessed using the Delirium Rating Scale-Revised-98. The association of baseline olfaction, delirium incidence, and delirium severity was examined in regression models adjusting for age, duration of cardiopulmonary bypass, logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE), and baseline cognition. Olfactory dysfunction was present in 30% of patients, and POD incidence was 44%. Pre-operative olfactory dysfunction was associated with both incident POD (OR=3.17, p=0.001) and greater severity of POD after cardiac surgery (OR=3.94 p<0.001) in models adjusted for age, duration of bypass, and a surgical risk score. The addition of baseline cognition attenuated the strength of the association, but it remained significant for incident POD (OR=2.25, p=0.04) and POD severity (OR 2.10, p=0.04). Poor baseline olfaction was associated with greater baseline cognitive dysfunction (p<0.001) and increased baseline plasma NfL concentrations (p=0.04). Neither age, cognition, nor baseline NFL concentration modified the association of impaired olfaction and delirium outcomes. Olfactory assessment may be a useful pre-surgical screening tool for the identification of patients undergoing cardiac surgery at increased risk of POD. Identifying those at highest risk for severe delirium and poor cognitive outcomes following surgery would allow for earlier intervention and pre-operative rehabilitation strategies, which could ultimately impact the functional disability and morbidity associated with POD.

Comparative analysis of different risk prediction tools after mitral Transcatheter edge-to-edge repair

BackgroundTranscatheter edge-to-edge repair (TEER) has become an established treatment for primary and secondary mitral regurgitation (PMR and SMR). The objective of this study was to compare the accuracy of different risk scores for predicting 1-year mortality and the composite endpoint of 1-year mortality and/or heart failure (HF) hospitalization after TEER. MethodsWe analyzed data from 206 patients treated for MR at a tertiary European center between 2011 and 2023 and compared the accuracy of different mitral and surgical risk scores: EuroSCORE II, GRASP, MITRALITY, MitraScore, TAPSE/PASP-MitraScore, and STS for predicting 1-year mortality and the composite of 1-year mortality and/or HF hospitalization in PMR and SMR. A subanalysis of SMR-only patients with the addition of COAPT Risk Score and baseline N-Terminal pro-Brain Natriuretic Peptide (NT-proBNP) list was also performed. ResultsMITRALITY had the best discriminative ability for 1-year mortality and the composite endpoint of 1-year mortality and/or HF hospitalization, with an area under the curve (AUC) of 0.74 and 0.74, respectively, in a composed group of PMR and SMR. In a SMR-only population, MITRALITY also presented the best AUC for 1-year mortality and the composite endpoint of 1-year mortality and/or HF hospitalization, with values of 0.72 and 0.72, respectively. ConclusionMITRALITY was the best mitral TEER risk model for both 1-year mortality and the composite endpoint of 1-year mortality and/or HF hospitalization in a population of PMR and SMR patients, as well as in SMR patients only. Surgical risk scores, MitraScore, TAPSE/PASP-MitraScore and NT-proBNP alone showed poor predictive values.

Three-year outcomes of surgical valve replacement with Dafodil™ pericardial bioprosthesis: Dafodil™-1 trial.

The Dafodil™-1 trial was designed to evaluate the clinical safety and performance of Dafodil™ pericardial bioprosthesis for replacing diseased native or prosthetic aortic or mitral valves in patients with advanced valvular heart disease (VHD). The Dafodil™-1 trial was a prospective, multicenter, first-in-human clinical trial. Patients were enrolled if they had advanced VHD requiring aortic valve replacement (AVR) or mitral valve replacement (MVR) with or without concomitant valve surgery and having surgical risk scores <4%. Major adverse cardiac events (MACE), including all-cause death, myocardial infarction (MI), and stroke; and hemodynamics were analyzed. A total of 136 patients (aortic: 67 and mitral: 69) were enrolled in the trial (with mean age-AVR group: 60.2 ± 8.3 years and MVR group: 49.7 ± 14.4 years). A total of 134 patients (aortic: 66 and mitral: 68) completed the 3-year follow-up (total 300 per 100 patient-years of follow-up). The AVR group demonstrated a significant reduction in the mean pressure gradients from 51.2 ± 24.1 mmHg at baseline to 11.1 ± 6.0 mmHg at the 3-year follow-up (p < 0.0001). The mean effective orifice area (EOA) improved from baseline (0.9 ± 0.6 cm2) to 3-year follow-up (1.8 ± 0.4 cm2) (p < 0.0001). In the MVR group, the mean indexed EOA (iEOA) increased significantly from baseline (0.7 ± 0.4 cm2/m2) to 3-year follow-up (1.1 ± 0.4 cm2/m2) (p < 0.001). There was significant improvement in New York Heart Association functional class and mean SF-12 scores in both groups. At 3-year follow-up, the MACE incidence was 2.3% per 100 patient-years (1.3% strokes per 100 patient-years and 1.3% deaths per 100 patient-years) for AVR group and 4.7% per 100 patient-years (0.6% strokes per 100 patient-years and 4.0% deaths per 100 patient-years) for MVR group. No cases of MI, structural valve deterioration and prosthetic valve endocarditis were reported. The AVR and MVR groups achieved 89.6% and 79.7% MACE-free survival, respectively at 3-year follow-up. The Dafodil™-1 trial demonstrated satisfactory outcomes of clinical safety, hemodynamic performance, and quality-of-life metrics. Additionally, no incidence of structural valve deterioration and very low rates of valve thrombosis during the 3-year follow-up period of Dafodil™-1 first-in-human trial indicated acceptable valve durability up to three years and similar outcomes are warranted for longer follow-ups as a primary goal. https://www.ctri.nic.in/Clinicaltrials/showallp.php?mid1=18377&EncHid=&userName=CTRI/2017/07/009008, CTRI/2017/07/009008.

The incidence and influencing factors of in-hospital frailty progression following transcatheter aortic valve implantation.

Objective Patients undergoing transcatheter aortic valve implantation (TAVI) are generally older and frailty is therefore an important clinical issue. The baseline degree of frailty is associated with the prognosis in patients undergoing TAVI; however, the incidence of in-hospital frailty progression and its influencing factors have not yet been elucidated. Methods This observational, single-center study retrospectively evaluated 281 patients who underwent TAVI. The degree of frailty at baseline and discharge was evaluated using the Clinical Frailty Scale (CFS). In-hospital frailty progression was defined as an increase of at least one level in the CFS score at discharge from baseline, and predictors of frailty progression were assessed. Results The median baseline CFS score was 4.0 (interquartile range: 3.0-4.0). In-hospital frailty progression was observed in 49 patients (17.4%). No significant differences were observed in age, sex, comorbidities, or surgical risk scores between patients with and without frailty progression. Patients with frailty progression experienced stroke more frequently during hospitalization than those without (12.2% vs. 1.3%, p = 0.001). A multivariable logistic analysis showed that in-hospital stroke was a significant predictor of frailty progression (odds ratio, 10.7; 95% confidence interval: 2.34-49.2, p = 0.002). Patients with frailty progression had a longer hospital stay than those without frailty progression [7.0 (4.0-17.0) vs. 4.0 (4.0-8.0) days, p = 0.001]. Conclusions In-hospital frailty progression was not uncommon in patients undergoing TAVI. Stroke incidence was a significant influencing factor in frailty progression, whereas baseline comorbidities and surgical risks were not.

Pre-Anesthesia Transfusion and Peri-Procedure Complications in Patients with Sickle Cell Disease on Hydroxyurea

Introduction Patients with sickle cell disease (SCD) are at increased risk of perioperative complications following general anesthesia including acute chest syndrome (ACS), vaso-occlusive pain episodes (VOE), and infection. The 2013 Transfusion Alternatives Preoperatively in SCD (TAPS) study found preoperative transfusion of patients with SCD, type SS or SB 0 thalassemia, prior to low- or medium-risk surgeries was associated with decreased perioperative complications. The American Society of Hematology 2020 guidelines for transfusion support for SCD suggest preoperative transfusion for those requiring general anesthesia (GA) lasting &amp;gt; 1 hour; however, it was noted that this should be individualized based on factors such as risk of surgery, baseline hemoglobin (Hb), and disease severity. With more broad use of Hydroxyurea (HU) that improves baseline Hb and decreases ACS and VOE frequency, we lack equipoise for when pre-anesthesia transfusion is indicated. We performed a chart review on pediatric patients with SCD at a large SCD center to determine clinician practice of pre-anesthesia transfusion versus no transfusion for patients on HU and the incidence of post-anesthesia complications with and without pre-anesthesia transfusion. Methods We performed an institutional review board approved retrospective chart review of patients with SCD (all genotypes) aged 0 to 22 years who underwent procedures or imaging studies with GA between the years 2019 and 2022 at our institution. Surgical risk score was assigned to all procedures per the TAPS study criteria. We examined the incidence of post-anesthesia complications occurring in the emergency department or hospital within 30 days post-anesthesia. Complications such as VOE, ACS, transfusion-related effects, and infection were recorded as categorical variables. Results We identified 165 patients with SCD who underwent GA at our center between 2019 and 2022: 56 of these patients were on hydroxyurea and 41 were not on hydroxyurea. We excluded 52 patients on chronic transfusion and 16 who had not consented for participation or had anesthesia encounters during a stem cell transplant admission. Among the 56 patients on HU, 34 received pre-anesthesia transfusion (2 by exchange transfusion) and 22 did not. The average Hb of those on HU who received pre-anesthesia transfusion was 8.64 g/dl (SD 1.1 g/dl) and of those who did not receive transfusion it was 9.4 g/dl (SD 1.33 g/dl) (p = 0.03, unpaired t-test). Among patients on HU who received transfusion, 4/34 (12%) had post-anesthesia complications and of those who did not receive transfusion, 6/22 (27%) had complications (p = 0.17, Fisher exact test) (Table). Among the transfused cohort, complications occurred after 2 low-risk procedures (ACS after an electrophysiology study with radiofrequency ablation and streptococcal infection after an abdominal exploratory laparoscopy), 1 medium-risk procedure (hematuria/abdominal pain after laparoscopic cholecystectomy) and 1 high-risk procedure (respiratory failure after coarctation of the aorta repair). Among patients who were not transfused, complications occurred after 2 imaging studies (ACS in the setting of parainfluenza infection after brain MRI and VOE after shoulder MRI), 2 low-risk procedures (ACS after laparoscopic appendectomy and VOE after adenoidectomy), and 2 medium-risk procedures (ACS after laparoscopic cholecystectomy and multiple admissions for 1 patient for ACS and VOE after endoscopic retrograde cholangiopancreatography). Conclusions In patients with SCD -SS or -SB 0 thalassemia on hydroxyurea undergoing procedures with anesthesia at our center, clinicians continued to prescribe pre-anesthesia transfusion for those with a Hb &amp;lt; 9 g/dl. The incidence of complications was higher in patients on HU who did not receive pre-anesthesia transfusion despite an average pre-procedure Hb of &amp;gt; 9 g/dL, but this was not statistically significant in our small sample size. However, these numbers are comparable to the findings of the TAPS study which found that 5/33 (15%) patients in the preoperative transfusion group had clinically important complications compared with 13/33 (39%) patients in the no transfusion group. These findings suggest that despite higher baseline Hb levels in the setting of HU use, patients with sickle cell disease may continue to benefit from pre-anesthesia transfusion but a randomized controlled trial is necessary.
