Preoperative Imaging Signs of Cerebral Malperfusion in Acute Type A Aortic Dissection: Influence on Outcomes and Prognostic Implications-A 20-Year Experience.

Acute type A aortic dissection (ATAAD) continues to be a subject of active research due to its high mortality rates and associated complications. Cerebral malperfusion in ATAAD can have a devastating impact on patients' neurological function and overall quality of life. We aimed to explore the risk profile and prognosis in ATAAD patients presenting with preoperative imaging signs of cerebral malperfusion (PSCM). We obtained patient data from our Aortic Dissection Registry, which included 480 consecutive ATAAD cases who underwent surgical repair between 2001 and 2021. Primary endpoint outcomes included the in-hospital and 30-day mortality, postoperative new neurological deficit, mechanical ventilation hours, and intensive care unit (ICU) length of stay. Of the total cohort, 82 patients (17.1%) had PSCM. Both groups had similar distributions in terms of age, sex, and body mass index. The patients in the PSCM group presented with a higher logistic EuroSCORE (47, IQR [31, 64] vs. 24, IQR [15, 39]; p < 0.001) and a higher portion of patients with a previous cardiac surgery (7.3% vs. 2.0%; p = 0.020). Intraoperatively, the bypass, cardioplegia, and aortic cross-clamp times were similar between both groups. However, the patients in the PSCM group received significantly more intraoperative packed red blood cells, fresh frozen plasma, and platelets transfusions (p < 0.05). Following the surgery, the patients who presented with PSCM had markedly longer ventilation hours (108.5 h, IQR [44, 277] vs. 43 h, IQR [16, 158], p < 0.001) and a significantly longer ICU length of stay (7 days, IQR [4, 13] vs. 5 days, IQR [2, 11]; p = 0.013). Additionally, the patients with PSCM had significantly higher rates of postoperative new neurological deficits (35.4% vs. 19.4%; p = 0.002). In the Cox regression analysis, PSCM was associated with significantly poorer long-term survival (hazard ratio (HR) 1.75, 95%CI [1.20-2.53], p = 0.003). Surprisingly, hypertension was shown as a protective factor against long-term mortality (HR: 0.59, 95%CI [0.43-0.82], p = 0.001). PSCM in ATAAD patients is linked to worse postoperative outcomes and poorer long-term survival, emphasizing the need for early recognition and tailored management.

Preoperative hypoalbuminemia and postoperative acute kidney injury in adult patients after elective on-pump cardiac surgery

Abstract Funding Acknowledgements Type of funding sources: None. Background An earlier published prospective cohort study evaluating the impact of malnutrition on cardiac surgery outcomes showed serum albumin ≤42 g/dL to be associated with a poor prognosis [1]. However, the association with kidney outcomes was not studied. The adverse effect of preoperative hypoalbuminemia on postoperative kidney injury and its cut-off value in on-pump cardiac surgery patients is still controversial [2]. Methods A retrospective matched case-control study based on the secondary analysis of the open-access dataset [3] was conducted. The research hypothesis was that preoperative hypoalbuminemia is independently associated with a higher risk of acute kidney injury (AKI) requiring postoperative new-onset dialysis. We defined cases as patients treated with new-onset dialysis for AKI and controls as those who did not. Hypoalbuminemia was defined as serum albumin of ≤42 g/L based on findings from the original study. The dataset counted 1178 adults from multiple centers who underwent elective cardiopulmonary bypass (CPB) cardiac surgery in 2011. We excluded patients with missing data and compared key demographic and medical history characteristics. Following the hypothesis, subjects were matched on the type of surgery they received (coronary, valvular, or combined) in a multiple conditional logistic regression model that included the hypoalbuminemia status, diabetes history, CPB time, and logistic EuroScore. Additionally, univariate regression with and without conditional matching was performed. Results In total, 831 (39 cases and 792 controls) subjects were included. Subjects shared similar demographics and medical history. Expectedly, cases had prolonged CPB and aortic cross-clamp time. The median CPB time in cases and controls was 120 and 79 min, respectively (p=0.001). The median aortic cross-clamp time was 79 in cases and 54 in controls (p=0.001). Hypoalbuminemia was observed in 18 cases (46%) in cases compared to 241 (30%) in controls (p=0.038). Multiple conditional regression demonstrated that the risk of postoperative AKI requiring dialysis was not associated with preoperative hypoalbuminemia (OR 1.43, [0.70, 2.89]). Similarly, univariate conditional regression showed no association (OR 1.84 [0.95, 3.53]). Only univariate unmatched regression resulted in statistical significance(OR 1.96 [1.03, 3.74]). The higher logistic EuroScore (OR 1.11, [1.06, 1.15]) and the longer cardiopulmonary bypass time (OR 1.01, [1.01, 1.02]), but not the history of diabetes (OR 0.61, [0.19, 1.88]), increased the odds of renal replacement therapy requirement. Conclusion In our study, preoperative hypoalbuminemia was not independently associated with a higher risk of postoperative AKI requiring new-onset dialysis after elective on-pump cardiac surgery. Patients who required dialysis had lower preoperative albumin levels, but the association between hypoalbuminemia ≤ 42 g/L and kidney outcomes could be confounded.

Catheter versus surgical approach for the management of concomitant aortic stenosis and coronary artery disease: An inverse probability treatment weighting analysis

Two therapeutic strategies are available when aortic stenosis and coronary artery disease coexist: a transcatheter approach, with percutaneous coronary intervention followed by transcatheter aortic valve replacement; and a surgical approach, consisting of surgical aortic valve replacement combined with coronary artery bypass graft. We sought to compare the outcomes of these two strategies. The study population consisted of 241 patients who benefited from aortic valve replacement and coronary revascularization (transcatheter, n=150; surgery, n=91). Patients in the transcatheter population were older (83.5 vs. 71.8years; P<0.001) and had a higher Logistic EuroSCORE(11.1% vs. 5.7%; P<0.001). At 30days postprocedure, patients who had surgery exhibited more life-threatening bleedings (12.1% vs 4.5%; P=0.034), acute kidney injury (12.1% vs. 1.3%; P<0.001) and atrial fibrillation (55.6% vs. 8.7%; P<0.001). After a median follow-up of 27months, the risk of major adverse cardiovascular or cerebrovascular events did not differ significantly between the two strategies (hazard ratio [HR] 1.41, 95% confidence interval [CI] 0.97-2.04; P=0.07), whereas estimated glomerular filtration rate<60mL/min (HR 2.22, 95%CI 1.58-3.12; P<0.001), peripheral artery disease (HR 2.00, 95%CI 1.37-2.91; P<0.001) and left ventricular ejection fraction<50% (HR 1.69, 95%CI 1.12-2.55; P=0.012) were associated with a negative prognosis. In our study, patients with aortic stenosis and coronary artery disease treated by catheter were older and had a higher co-morbidity burden than those treated by surgery. The surgical strategy was associated with a higher rate of 30-day complications, but long-term outcomes were similar between the two strategies.

Should more patients be offered repair for mitral valve endocarditis? a single-centre 15-year experience

ObjectiveTo describe the long-term outcomes of mitral valve repair (MVr) versus mitral valve replacement (MVR) in patients with native valve infective endocarditis (IE) at a centre with high-repair rates.MethodsWe conducted a retrospective single-centre cohort study. From 2005 to 2021, 183 patients with active or healed native valve IE were included. The primary outcome was long-term mortality. Patient status was last confirmed 31 March 2021. Secondary outcomes were post-operative MR, MV reoperation, length of post-operative intensive care stay and total hospital stay.Results85 patients (46.4%) underwent MVr and 98 (53.6%) underwent MVR. Follow-up was 98.9% complete. Mean follow-up time was 5.3 years with 17% of patients reaching a follow-up time of over 10 years. There were 47 deaths (25.7%) within the follow-up period. MVR patients were more likely to have higher logistic EuroSCORE, active IE and were less likely to have elective surgery. In multivariate Cox proportional hazards analysis, there was no significant difference in long-term mortality between MVr and MVR groups (hazard ratio 1.09, 95% confidence interval [0.59–2.00]). In Kaplan–Meier analysis, MVR patients had a higher all-cause mortality although there was no significant difference at the endpoint. Propensity score matching analysis showed a significantly higher mortality in the replacement group instead (p = 0.002), Subgroup analysis revealed there remained no significant difference in mortality even in patients with active IE (P-interaction = 0.859) or non-elective surgery (P-interaction = 0.122). MV reoperation (odds ratio 1.00 [0.24–4.12]), post-operative intensive care stay (p = 0.9650) and total hospital stay (p = 0.9144) were comparable.ConclusionsOur data demonstrates repair was at least non-inferior to replacement in IE, supporting more aggressive use of repair. There is no reason the general principle of why repair is superior to replacement should not hold in IE, with enough operator expertise. Other experienced units should be encouraged to increase repair rates as feasible in line with current guidelines.

Male-Female Differences in Ascending Aortic Aneurysm Surgery: 25-Year Single Center Results

The aim of this study was to improve insight into male-female differences in patients undergoing ascending aortic aneurysm surgery. Consecutive patients that underwent ascending aortic aneurysm surgery between January 1991-December 2016 were retrospectively analyzed. Patient and procedural characteristics, 30-day mortality, and survival were compared between male and female patients. Multivariable Cox-regression analysis was performed to explore differences in factors associated with long-term mortality. Of 631 included patients, 36% were female patients. They were older (66 (55.9-72.9) vs 56 (44.1-67.3) years, p < 0.001), had a higher logistic EuroSCORE (12 (8-17) vs 8 (5-12), p < 0.001), and underwent concomitant arch surgery more often (74% vs 54%, p < 0.001). Aortic diameter (5.5 (5.0.6.5) vs 5.5 (5.0-6.0) cm, p=0.025) and Aortic Size Index (3.15 (2.80-3.65) vs 2.70 (2.42-3.00) cm/m2, p < 0.001) were larger in female patients. Early mortality was 0.9% in female patients and 2.0% in male patients (p=0.51). Adjusted 15-year survival was comparable between male and female patients. Multivariable Cox-regression did not identify an independent association between female sex and mortality. In males a larger aortic diameter (HR1.38 per centimeter increase, 95%-CI 1.03-1.85, p=0.003) was an independent factor associated with mortality, and in female patients a larger BSA (HR0.08 per 1kg/m2 increase, 95%-CI 0.01-0.49, p=0.007) was an independent risk-reducing factor. Female patients presented at older age and with more advanced disease. Increased awareness for ascending aortic pathology and timely referral may result in better preoperative profiles in female patients. This may improve outcomes after ascending aortic aneurysm surgery.

Cardiac surgery in older patients: hospital outcomes during a 15-year period from a complete national series.

OBJECTIVESThe objective was to review national trends in activity and hospital outcomes in older patients having cardiac surgery over a 15-year time period.METHODSData were collected prospectively and uploaded to the National Institute for Cardiovascular Outcomes Research electronically. Data were validated, cleaned and processed using reproducible algorithms. Mortality was death in hospital after index operation.RESULTSA total of 227 442 cardiac procedures were recorded in patients aged ≥70 years of which 46 354 were in those aged ≥80 years. Overall patients aged ≥70 years represented 43% of all adult cardiac surgery in the most recent study year. The annual proportion of surgery in patients ≥80 years increased from 4.1% to 10.8% between the first and last study years. There has been a significant linear increase in octogenarian valve [β 67.44, 95% confidence interval (CI) 55.04 to 79.83, P < 0.001] and coronary artery bypass graft surgery (β 32.53, 95% CI 6.16 to 58.90, P = 0.020) patients. In-hospital mortality reduced significantly for patients aged 70–79 years (β −0.17, 95% CI −0.20 to −0.13, P < 0.001) and all patients aged ≥80 (β −0.37, 95% CI −0.45 to −0.30, P < 0.001). The median length of hospital stay was 7 days for 70–79 and 9 days for ≥80 group, compared with 7 days for the whole cohort <70 years.CONCLUSIONSThis study represents the largest complete validated national dataset of cardiac surgery in the entire population of older patients. Octogenarians represent 11% of adult patients having cardiac surgery by the end of the study period, a three-fold increase from the start. In-hospital mortality in patients aged ≥80 years halved during study period to only 4% despite high logistic EuroSCORE of 15%. Cardiac surgery in octogenarians places a higher demand on resources, however, with an increased postoperative length of stay.

Outcomes of trans-catheter versus surgical aortic valve replacement for patients with classic low-flow low-gradient aortic stenosis

Abstract Background Classical low-flow low-gradient aortic stenosis (cLFLG-AS) is frequently encountered within clinical practice [1], and is often associated with high mortality [2]. Whilst aortic valve replacement can improve outcomes, there is a lack of real-world data guiding the decision between trans-catheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) in this specific patient cohort. Purpose To compare outcomes between TAVI and SAVR in patients with cLFLG-AS. Methods cLFLG-AS was defined by an aortic valve area &amp;lt;1cm2, mean gradient &amp;lt;40mmHg or peak velocity &amp;lt;4m/s and left ventricular ejection fraction &amp;lt;50%. All patients who met cLFLG-AS criteria who underwent TAVI or SAVR at our tertiary referral centre between 2015 and 2020 were included. Inverse probability weighting was used to adjust for differences in baseline characteristics and the non-random assignment of treatment modalities. The primary end-point was all-cause mortality. Secondary end-points were procedure-related permanent pacemaker implantation, renal replacement therapy (RRT) and stroke. Results 322 patients were included (220 TAVI and 102 SAVR). Baseline characteristics were: male sex 70%, mean gradient 30mmHg (23–35), aortic valve area 0.8cm2 (0.6–0.9). Patients undergoing TAVI were older than the SAVR group (81.3±8.5 vs 70.6±11.1 years, p&amp;lt;0.0001) with higher Logistic Euroscore (19.3 (11.8–32.3) vs 7.1 (3.7–14.1), p&amp;lt;0.0001) (figure 1). At median follow-up of 2.7 years (1.5–4.1), 99 patients had died; 70 (31.8%) had TAVI and 29 (28.4%) had SAVR. Both unweighted and weighted Kaplan-Meier curve analysis was performed; there was similar survival between SAVR and TAVI (log rank test 0=0.27 and p=0.4 respectively) (figure 2). Adjusted hazard ratio (HR) for mortality with SAVR was 0.78 unweighted (95% CI 0.5–1.21; p=0.27) and 0.66 weighted (95% CI 0.26–1.64; p=0.37). In terms of contributory procedural factors, concomitant multiple valve intervention in the SAVR group independently affected mortality (HR 5.47, 95% CI 2.52–11.51, p&amp;lt;0.001). There was no difference in permanent pacemaker insertion or stroke across the two groups, but rates of RRT were higher in SAVR cohort (13.7% vs 0%, p&amp;lt;0.001). Conclusions Despite the TAVI cohort being both older and at higher risk, there was no observed difference in mortality between TAVI and SAVR in the mid-term. Deciding upon intervention choice can therefore be based upon criteria other than the specific presence of a classic low-flow low-gradient state.

Temporal Trends, Characteristics, and Outcomes of Infective Endocarditis After Transcatheter Aortic Valve Replacement

AbstractBackgroundProcedural improvements combined with the contemporary clinical profile of patients undergoing transcatheter aortic valve replacement (TAVR) may have influenced the incidence and outcomes of infective endocarditis (IE) following TAVR. We aimed to determine the temporal trends, characteristics, and outcomes of IE post-TAVR.MethodsObservational study including 552 patients presenting definite IE post-TAVR. Patients were divided in 2 groups according to the timing of TAVR (historical cohort [HC]: before 2014; contemporary cohort [CC]: after 2014).ResultsOverall incidence rates of IE were similar in both cohorts (CC vs HC: 5.45 vs 6.52 per 1000 person-years; P = .12), but the rate of early IE was lower in the CC (2.29‰ vs 4.89‰, P &amp;lt; .001). Enterococci were the most frequent microorganism. Most patients presented complicated IE ( CC: 67.7%; HC: 69.6%; P = .66), but the rate of surgical treatment remained low (CC: 20.7%; HC: 17.3%; P = .32). The CC exhibited lower rates of in-hospital acute kidney injury (35.1% vs 44.6%; P = .036) and in-hospital (26.6% vs 36.4%; P = .016) and 1-year (37.8% vs 53.5%; P &amp;lt; .001) mortality. Higher logistic EuroScore, Staphylococcus aureus etiology, and complications (stroke, heart failure, and acute renal failure) were associated with in-hospital mortality in multivariable analyses (P &amp;lt; .05 for all).ConclusionsAlthough overall IE incidence has remained stable, the incidence of early IE has declined in recent years. The microorganism, high rate of complications, and very low rate of surgical treatment remained similar. In-hospital and 1-year mortality rates were high but progressively decreased over time.

Sex differences in patients undergoing transcatheter aortic valve replacement in Asia

Reclassification of aortic stenosis by fusion of echocardiography and computed tomography in low-gradient aortic stenosis.

BackgroundThe integration of computed tomography (CT)-derived left ventricular outflow tract area into the echocardiography-derived continuity equation results in the reclassification of a significant proportion of patients with severe aortic stenosis (AS) into moderate AS based on aortic valve area indexed to body surface area determined by fusion imaging (fusion AVAi). The aim of this study was to evaluate AS severity by a fusion imaging technique in patients with low-gradient AS and to compare the clinical impact of reclassified moderate AS versus severe AS.MethodsWe included 359 consecutive patients who underwent transcatheter aortic valve implantation for low-gradient, severe AS at two academic institutions and created a joint database. The primary endpoint was a composite of all-cause mortality and rehospitalisations for heart failure at 1 year.ResultsOverall, 35% of the population (n = 126) were reclassified to moderate AS [median fusion AVAi 0.70 (interquartile range, IQR 0.65–0.80) cm2/m2] and severe AS was retained as the classification in 65% [median fusion AVAi 0.49 (IQR 0.43–0.54) cm2/m2]. Lower body mass index, higher logistic EuroSCORE and larger aortic dimensions characterised patients reclassified to moderate AS. Overall, 57% of patients had a left ventricular ejection fraction (LVEF) <50%. Clinical outcome was similar in patients with reclassified moderate or severe AS. Among patients reclassified to moderate AS, non-cardiac mortality was higher in those with LVEF <50% than in those with LVEF ≥50% (log-rank p = 0.029).ConclusionsThe integration of CT and transthoracic echocardiography to obtain fusion AVAi led to the reclassification of one third of patients with low-gradient AS to moderate AS. Reclassification did not affect clinical outcome, although patients reclassified to moderate AS with a LVEF <50% had worse outcomes owing to excess non-cardiac mortality.

Predictors of short- and long-term outcomes of patients undergoing transcatheter mitral valve edge-to-edge repair.

Transcatheter mitral valve repair (TMVR) by edge-to-edge therapy is an established treatment for severe mitral valve regurgitation (MR). Symptomatic and prognostic benefit in functional MR has been shown recently; nevertheless, data on long-term outcomes are sparse. We analyzed survival of patients treated with isolated edge-to-edge repair from June 2010 to March 2018 (primarily combined edge-to-edge repair with other mitral valve interventions was excluded) in a retrospective monocentric study. Overall, 627 consecutive patients (47.0% females, 78.6 years in mean) were included. Leading etiology was functional MR (57.4%). Follow-up regarding survival was available in 97.0%. While 97.6% were discharged alive, 75.7% were alive after a 1-year, 54.5% after 3-year, 37.6% after 5-year and 21.7% after 7-year follow-up. Higher logistic Euroscores and comorbidities such as COPD and renal insufficiency were associated with higher in-hospital and 1-year mortality. Importantly, in-hospital survival increased over the years. With the present study we established high survival rates at discharge and after 1 year of patients treated with TMVR. This goes along with high implantation numbers, increased interventional experience and a better in-hospital survival over the years. Long-term mortality in turn was substantially influenced by comorbidities.

P918Tricuspid regurgitation in patients undergoing transcatheter aortic valve implantation

Abstract Background Transcatheter aortic valve implantation (TAVI) has become the treatment of choice in elderly patients with severe aortic stenosis and increased surgical risk. A significant number of these elderly patients have concomitant tricuspid valve regurgitation. The impact on outcome, however, is still matter of debate. Objectives In this prospective observational study, we investigated the impact of concomitant tricuspid regurgitation (TR) on outcome in patients undergoing transcatheter aortic valve implantation. Methods Between February 2008 and May 2018, 1411 patients with severe symptomatic aortic stenosis and increased operative risk underwent TAVI at the Heart Center Bonn and participated in this study, after written informed consent was obtained. Before TAVI procedure, all patients underwent a careful cardiac evaluation and interdisciplinary discussion within the local, institutional Heart Team. The pre-interventional 3D echocardiography was used to determine the degree of tricuspid valve regurgitation. According to the severity of TR, patients were divided into two groups; patients with TR &lt; II and patients with moderate to severe TR ≥ II andcompared regarding rates of mortality after 1 year of follow-up between the two groups. Results Out of 1411 TAVI patients, 802 (56.8%) had tricuspid regurgitation &lt; II, 610 (43.2%) patients suffered from tricuspid regurgitation ≥ II. The mean age of our study population was 81.1 (±6.5). The baseline characteristics did not differ significantly between the two groups, such as extracardiac arteriopathy (TR &lt; II: 44% vs TR ≥ II: 41.6%; p=0.37), diabetes (TR &lt; II: 27.5% vs TR ≥ II: 27.7%; p=0.92) or arterial hypertension (TR &lt; II: 91% vs TR ≥ II: 93.2%; p=0.64). However, patients with concomitant TR ≥ II had significantly more often NYHA class IV (TR &lt; II: 5.0% vs TR ≥ II: 15.4%; p&lt;0.001) and a higher logistic EuroSCORE (TR &lt; II: 12.9 (8.8/21.2) vs TR ≥ II: 20.6 (13.1/33.4); p&lt;0.001). Additionally, patients with a TR ≥ II had significantly more often a concomitant mitral regurgitation ≥ II (TR &lt; II: 43.3% vs TR ≥ II: 60.4%; p&lt;0.001). Comparing rates of mortality, we found a significant association between the degree of tricuspid regurgitation and 1-year mortality in patients undergoing TAVI (TR &lt; II: 85 (10.6%) vs. TR ≥ II: 136 (22.3%); p&lt;0.001), as presented in Figure 1. Figure 1 Conclusion Moderate to severe tricuspid valve regurgitation is associated with higher rates of mortality in patients undergoing transcatheter aortic valve implantation. Our results are hypothesis-generating and it has to be elucidated whether the severity of TR is only a surrogate for more advanced stage of aortic stenosis or whether it is causative so that mortality could be reduced by its treatment.

Significance of the CAPRI risk score to predict heart failure hospitalization post-TAVI: The CAPRI-HF study

BackgroundPredictors of heart failure (HF) hospitalization after transcatheter aortic valve implantation (TAVI) are not well defined. CAPRI is a score for predicting 1-year post-TAVI cardiovascular and all-cause mortality. The aim of the present study is to assess the prognostic significance of the CAPRI score for HF hospitalization 1 year after TAVI. Methods and resultsCAPRI-HF is an ancillary study of the C4CAPRI trial, analyzing 409 consecutive patients treated by TAVI. The primary outcome was hospitalization for HF during the first year post-intervention. The prognostic value of the CAPRI score was assessed by multivariable analysis adjusted for diabetes, atrial fibrillation, vascular route, pacemaker implantation, post-TAVI aortic regurgitation, transfusion and pulmonary artery systolic pressure. A subanalysis focused on patients with low-gradient aortic stenosis (LGAS). At 1 year, HF hospitalization occurred in 78 (19.9%) patients. Patients with HF were more prone to have diabetes, atrial fibrillation, renal dysfunction, lower mean aortic gradient, higher logistic EuroSCORE and higher CAPRI score (p < .05 for all associations).In the multivariable analysis, CAPRI score was the sole predictor of HF: hazard ratio (HR) for each 0.1 CAPRI score increase was 1.065, 95% confidence interval (CI) 1.021–1.110. This was confirmed when adjusted for EuroSCORE: HR 1.066, 95% CI 1.024–1.110. The predictive power of the CAPRI score increased for LGAS: HR 1.098, 95% CI 1.028–1.172. ConclusionsCAPRI score helps predict HF post-TAVI. Including the score in the decision-making process may help selecting candidates for TAVI and identifying patients who need close monitoring post-procedure.

Influence of marital status in patients undergoing transcatheter aortic valve implantation.

Marital status has been described to affect outcome in cardiovascular diseases, however its impact on patients undergoing transcatheter aortic valve implantation (TAVI) is unknown. We therefore aimed to assess the impact of marital status in patients undergoing TAVI. Between 2011 and 2015, 779 patients undergoing transfemoral TAVI with known marital status were included in the analysis. The primary endpoint of the study was the composite of cardiac death and readmission for congestive heart failure (CHF) at one year. Mean age was 80.7±5.9 years, 47.8% were female and median logistic EuroScore was 12.7% (8.13-19.39%). Forty-three point three percent of patients were not married. Compared to married patients, unmarried patients were older (82.4±5.5 vs. 79.5±5.8 years; P<0.001), more often female (73.3% vs. 28.3%; P<0.001), presented with a higher logistic EuroScore [13.1% (9.5-21.5%) vs. 11.7% (7.0-18.5%); P<0.001], and more symptomatic with New York Heart Association functional class III/IV (69.7% vs. 60.6%; P=0.009). At one year the incidence of the primary endpoint was higher in unmarried patients (18.7% vs. 12.0%; P=0.011) which was mainly driven by more admissions for CHF (14.1% vs. 7.8%; P=0.007). After multivariable adjustment, marital status was borderline significant regarding CHF (HR 0.61, 95% CI: 0.37-1.02; P=0.06) but not the primary endpoint. Unmarried patients undergoing TAVI showed a higher incidence of cardiac death or CHF at one year. Hence, marital status should be taken into account in patients with aortic stenosis subjected to TAVI. Whether closer monitoring and intensified medical follow-up improves outcomes remains to be investigated in future studies.

Impact of Hemodynamic Support on Outcome in Patients Undergoing High-Risk Percutaneous Coronary Intervention

The use of left-ventricular (LV) hemodynamic support might facilitate high-risk percutaneous coronary interventions (PCI) in patients with complex coronary artery disease. The impact on outcome is a matter of ongoing debate. We assessed the outcome of high-risk patients who underwent protected PCI in comparison to patients who underwent unprotected high-risk PCI. One hundred and thirty nine patients underwent nonemergent high-risk PCI; 24 (17%) patients underwent protected PCI. To address selection bias, we performed a propensity score matched subanalysis. The primary end point was the occurrence of a major adverse cardiac event during the first year. Patients with protected PCI had a higher logistic EuroSCORE (logES) (protected PCI: 19% vs unprotected PCI: 12%; p = 0.01), a higher SYNTAX score (45 vs 36, p = 0.07), and significantly more often reduced LV function (40% vs 55%; p < 0.001). In protected PCI patients, complete revascularization was more often achieved (87% vs 58%, p = 0.007) without the occurrence of death at 30 days of follow-up (0% vs 4%, p = 0.31). After propensity score matching, patients who underwent protected PCI had a similar 1-year major adverse cardiac event rate compared with patients who underwent unprotected PCI (21% vs 17%, p = 0.67), despite significantly higher procedural complexity for example, more often complex left main bifurcation lesions (71% vs 29%; p = 0.004). In conclusion, 1-year outcome of patients who underwent protected PCI was not different from that in patients with less complex procedures without hemodynamic support, despite more complex coronary anatomy, a higher comorbidity burden, and more often reduced LV function.

Two cases of lobectomy for lung cancer after transcatheter aortic valve implantation

BackgroundThe age of patients with lung cancer is advancing, and the number of patients with lung cancer who have cardiac diseases is expected to increase. Recently, the rate of transcatheter aortic valve implantation (TAVI) has increased as treatment for aortic stenosis (AS). TAVI is minimally invasive compared with conventional aortic valve replacement. We herein report two patients with lung cancer who underwent lobectomy after TAVI for severe AS.Case presentationTwo patients with AS and lung cancer were treated with two-stage surgery of TAVI followed by lobectomy. In patient 1 (77 years of age), conventional aortic valve replacement was considered to be risky because of his history of coronary artery disease and thoracic aortic aneurysm and his relatively high logistic euroSCORE. He underwent TAVI followed by right middle and lower lobectomy. In patient 2 (75 years of age), TAVI was chosen because the patient had poor ADL due to spinal canal stenosis and had taken immunosuppressant agents after a kidney transplantation. He underwent TAVI followed by right lower lobectomy. The postoperative course of the two patients was uneventful.ConclusionsTwo-stage surgery of TAVI and lung resection could be a viable option for patients with both lung cancer and severe AS, for whom conventional AVR by an open-heart operation is not indicated.

Prognostic value of impaired hepato-renal function assessed by the MELD-XI score in patients undergoing percutaneous mitral valve repair.

The objective of this study was to assess the prognostic value of the Model for End-stage Liver Disease (MELD)-XI score in patients undergoing PMVR with the MitraClip system. MELD-XI score, which was originally developed for prognostic assessment in patients with advanced liver disease, has been reported as a predictor of outcome in heart failure patients. A total of 192 consecutive patients undergoing percutaneous mitral valve repair (PMVR) were included into final analysis. MELD-XI score was calculated on the day of the procedure and patients were categorized into three groups based on MELD-XI score and compared with regards to clinical characteristics and outcomes following PMVR. MELD-XI > 12 was associated with male gender, higher logistic EuroSCORE, reduced left ventricular ejection fraction, enlarged right ventricular end-diastolic diameter, degree of mitral regurgitation, increased NT-proBNP serum levels and elevated right atrial pressures. Youden-Index revealed a cutoff of 16 in the MELD-XI score as best predictor of one-year all-cause mortality. Kaplan-Meier analysis and the log-rank test confirmed increased one-year mortality in patients with critically high score above 16 (mortality MELD-XI score > 16 vs 16-12 vs <12:39% vs 9%. vs 15%; P = 0.005). Compared to patients with lower MELD-XI score, these patients exhibited a more than 3-fold increased one-year mortality after PMVR. Given the high mortality in patients with a MELD-XI score > 16, these patients require a high-risk preoperative assessment and should undergo a careful discussion within the heart team for the best treatment option given the considerable one-year mortality following PMVR.

Predictores de necesidad de marcapasos permanente y alteraciones de la conducción con el implante transcatéter de una nueva válvula aórtica autoexpandible

Introduction and objectivesThe incidence of permanent pacemaker implantation (PPI) and new conduction abnormalities (CA) with the ACURATE neo (Symetis S.A., Eclubens, Switzerland) has not been studied in detail. We aimed to analyze their predictors, evaluating patient- and device-related factors, including implantation depth and device-to-annulus ratio (DAR). MethodsTwo analyses of a multicenter population were performed: new PPI in pacemaker-naive patients (n = 283), and PPI/new-CA in patients without prior CA or pacemaker (n = 232). ResultsA new PPI was required in 9.9% of patients, who had a higher body mass index, higher rate of right bundle branch block and bradycardia. Neither implantation depth nor DAR differed in patients with PPI compared with those without. In the multivariable analysis neither DAR (OR, 1.010; 95%CI, 0.967-1.055; P = .7) nor implantation depth (OR, 0.972; 95%CI, 0.743-1.272; P = .8) predicted PPI. Only high body mass index, bradycardia and right bundle branch block persisted as independent predictors. PPI/new-onset CA occurred in 22.8% of patients and was associated with a higher logistic EuroSCORE. Neither implantation depth nor DAR differed in patients with PPI/new-CA vs those without (7.3 ± 1.9 vs 7.1 ± 1.5mm; P = .6 and 41.0 ± 7.9 vs 42.2 ± 10.1%; P = .4). The only predictor of PPI/new-CA was a higher logistic EuroSCORE (OR, 1.039; 95%CI, [1.008-1.071]; P = .013). ConclusionsNew PPI and new-onset CA rates were low with the ACURATE neo. These were mainly influenced by patient characteristics and not by device-depending factors.Full English text available from: www.revespcardiol.org/en
