Comparison of ultrasound guidance and palpation technique for femoral artery catheterization in children undergoing cardiac surgery.

The aim of this study was compare the palpation technique and ultrasound-guidance for femoral artery catheterization in pediatric patients undergoing surgery for congenital heart disease. This prospective and randomized controlled study included American Society of Anesthesiologists III-IV 40 children who underwent congenital heart surgery. The patients were divided into two groups; ultrasound-guided catheterization group and palpation-guided catheterization group. Demographic and clinical characteristics of the patients, access time, success rate, number of attempts, first-attempt success, number of trials, and failed cannulations were recorded. The diameter of the femoral artery was significantly shorter, access time and numbers of trials were significantly lower, and first-attempt success rate was significantly higher in the US group. The complication rate was significantly higher in the P group. The number of failed catheterization was higher in the P group. Total cost required for the procedure was significantly lower in the US group. We found that ultrasound-guided arterial catheterization increases the success rate and the number of successful catheterizations, while reducing the overall procedure time, incidence of complications, and cost. Therefore, we believe that the use of ultrasound guidance in arterial catheterization in pediatric cardiac surgery would be a better choice.

Approach to red blood cell transfusions in post-operative congenital heart disease surgery patients: when to stop?

The best transfusion approach for CHD surgery is controversial. Studies suggest two strategies: liberal (haemoglobin ≤ 9.5 g/dL) and restrictive (waiting for transfusion until haemoglobin ≤ 7.0 g/dL if the patient is stable). Here we compare liberal and restrictive transfusion in post-operative CHD patients in a cardiac intensive care unit. Retrospective analysis was conducted on CHD patients who received liberal transfusion (2019-2021, n=53) and restrictive transfusion (2021-2022, n=43). The two groups were similar in terms of age, gender, Paediatric Risk of Mortality-3 score, Paediatric Logistic Organ Dysfunction-2 score, Risk Adjustment for Congenital Heart Surgery-1 score, cardiopulmonary bypass time, vasoactive inotropic score, total fluid balance, mechanical ventilation duration, length of cardiac intensive care unit stay, and mortality. The liberal transfusion group had a higher pre-operative haemoglobin level than the restrictive group (p < 0.05), with no differences in pre-operative anaemia. Regarding the minimum and maximum post-operative haemoglobin levels during a cardiac intensive care unit stay, the liberal group had higher haemoglobin levels in both cases (p<0.01 and p=0.019, respectively). The number of red blood cell transfusions received by the liberal group was higher than that of the restrictive group (p < 0.001). There were no differences between the two groups regarding lactate levels at the time of and after red blood cell transfusion. The incidence of bleeding, re-operation, acute kidney injury, dialysis, sepsis, and systemic inflammatory response syndrome was similar. Restrictive transfusion may be preferable over liberal transfusion. Achieving similar outcomes with restrictive transfusions may provide promising evidence for future studies.

Central venous-to-arterial CO2 difference as a biomarker of outcome in children who underwent surgery for congenital heart disease.

In congenital heart surgery, low cardiac output syndrome (LCOS) is a major cause of morbidity in the immediate post-operative period. A decrease in cardiac output leads to an increase in tissue oxygen consumption. Several biomarkers such as venous oxygen saturation (SvO2), arteriovenous oxygen difference (DavO2), and lactate can assess tissue perfusion in the presence of LCOS. Recently, central venous to arterial CO2 difference (ΔCO2) has been proposed as a biomarker of tissue ischemia that could be used as a predictor of death in neonatal patients. This study aimed to analyze the relationship between ΔCO2 and immediate post-operative outcomes in pediatric patients undergoing congenital heart surgery and its correlation with DavO2, SvO2, and lactate. We conducted a longitudinal study of patients aged 0-18 years who underwent congenital heart surgery with or without cardiopulmonary bypass at the Instituto Nacional de Pediatría, from March 2019 to March 2021. Eighty-two patients were included; the median age was 17 months. About 59% had a ΔCO2 ≥ 6 mmHg. Patients with ΔCO2 ≥ 6 mmHg had a vasoactive-inotropic score > 5 (p < 0.001), DavO2 > 5 mL/dL (p = 0.048), and lactate > 2 mmol/L (p = 0.027), as well as a longer hospital stay (p = 0.043). Patients with ΔCO2 > 6 mmHg and vasoactive-inotropic score ≥ 10 were 12.6 times more likely to die. ΔCO2 is a good marker of tissue hypoperfusion and outcome in the post-operative period of congenital heart surgery.

Effectiveness of cardiac palliative surgery for trisomy 18 patients with increased pulmonary blood flow.

Congenital heart disease (CHD) is common among patients with trisomy 18 (T18), but cardiac surgery has been rarely indicated for T18 patients due to their short life span. Although the therapeutic effects of aggressive interventions were recently demonstrated for T18 patients, the subjects and factors examined varied, resulting in inconsistent findings. Therefore, the effects of cardiac surgery for T18 remain unclear. We herein investigated the outcomes of cardiac palliative surgery for CHD with increased pulmonary blood flow in T18 patients. 27 patients were examined: 13 (48.1%) underwent cardiac palliative surgery and 14 (51.9%) did not. Median survival times in the no-surgery and surgery groups were 223.0 days (95% confidence interval [CI]: 46-361 days) and 723.0 days (95% CI: 360-1447 days), respectively. The number of patients with pulmonary hypertension significantly differed between the two groups (5 of 14 in the no-surgery group and 0 in the surgery group). Five of 14 patients in the no-surgery group and 10 of 13 in the surgery group were discharged to home care (odds ratio: 10.8 [95% CI: 1.07-110.0]). Therefore, cardiac palliative surgery may be used to treat CHD with increased pulmonary blood flow in T18 patients.

Aerosolized lidocaine to reduce tracheal suction-associated pain after pediatric congenital heart surgery: A randomized, double-blind, placebo-controlled trial

BackgroundIn children undergoing heart surgery for congenital heart disease (CHD), postoperative pain is associated with changes in the respiratory system that can lead to complicated courses and poor outcomes. Respiratory therapy (RT) can restore respiratory function through manual techniques and tracheal suction (TS). However, TS itself can cause pain, leading to hemodynamic and respiratory manifestations, such as tachycardia, hyper- or hypotension, tachypnea, increased work-of-breathing, patient-ventilator asynchrony, among others. ObjectivesThe aim of this study was to investigate whether RT/TS increases pain and whether inhaled lidocaine can attenuate pain increase in infants and children undergoing surgery for CHD. MethodsDouble-blind, randomized, placebo-controlled trial at a pediatric intensive care unit in a Brazilian tertiary-care university hospital. Patients <18 years submitted to open-heart surgery for CHD were included and randomized to receive either aerosolized lidocaine (1 mg/kg) or placebo before RT/TS. Pain was assessed by the Face, Legs, Activity, Cry, Consolability pain scale – revised (FLACC-R), along with hemodynamic and ventilatory parameters, before and 10 min after RT/TS start on postoperative days 1, 3, and 7 given they were on mechanical ventilation. Results119 patients were included. RT/TS induced minor changes in pain, which were not attenuated by lidocaine (confirmed in multivariate analysis). RT/TS also caused minor, clinically not relevant effects in hemodynamic and ventilatory parameters, which were also not modified by lidocaine. ConclusionRespiratory therapy with tracheal suction did not increase postoperative pain in ventilated children after congenital heart surgery until the 7th day, nor did aerosolized lidocaine exhibit any clinically significant effect on pain or other hemodynamic or ventilatory parameters.Registered at REBEC: RBR-10vtd55m.

Is the combination of conventional ultrafiltration and modified ultrafiltration superior to modified ultrafiltration in pediatric open-heart surgery?

ABSTRACT Background: Cardiopulmonary bypass (CPB) during open-heart surgery is associated with increased body fluids as a consequence of hemodilution due to the use of CPB. Ultrafiltration (UF) is a method used to decrease the body fluid volume on CPB. Aims and Objectives: This study aimed to compare the effects of combined conventional UF (CUF) and modified UF (MUF) versus MUF on the clinical outcomes of pediatric patients undergoing open-heart surgery for congenital heart disease. Materials and Methods: This was a prospective, single-center, randomized, and double-blinded clinical study that involved 74 pediatric patients undergoing open-heart surgery on CPB. Patient management was standardized. Preoperative Aristotle comprehensive complexity level, ultrafiltrate volumes, hematocrit, hemodynamic data, transesophageal echocardiographically (TEE) determined ejection fraction (EF), fractional area change (FAC), temperature drift, arterial oxygenation, time of extubation, ventilation, comparison of inotropic drugs, postoperative chest tube drainage, cardiac care unit (CCU), and hospital length of stay (LOS) were recorded in both groups. The analysis was conducted using SPSS-23.0, IBM, Armonk, NY, USA. Results: There was no mortality in both groups. Technical difficulties prevented the completion of MUF in two patients out of 37 in the CUF + MUF group. In this study, there were 43.26% of females and 56.75% of males, with a median age of 439 days, a mean weight of 9.98 kg, and an Aristotle Comprehensive Complexity score of level 2. Group CUF + MUF had a greater ultrafiltrate volume of 122 ± 39.7 ml (P = 0.036). The duration of ventilatory support was 11.2 ± 6.4 h versus 34.4 ± 5.7 h (P = 0.013), average CCU LOS was 4.3 ± 3.5 days versus 7.2 ± 3.6 days (P = 0.008), and chest tube drain in the first 48 h was 89.76 ± 34.82 ml versus 106.65 ± 47.29 ml (P = 0.029) in groups CUF + MUF and MUF, respectively. Inotropic infusion requirements were significantly lower in the CUF + MUF group compared to the MUF group. EF and FAC were 14% and 5% higher at 45 min in group CUF + MUF, respectively. Conclusions: The advantage of combining CUF and MUF over MUF is the significant improvement in the hemodynamic status of patients, which significantly decreases the duration of mechanical ventilation, average CCU LOS, inotrope requirements after surgery, and chest tube drain in the first 48 h.

Association of albuminuria with kidney function and hemodynamic disturbance in pre-school children who undergo congenital heart disease surgery.

We validated the prevalence of albuminuria and its association with kidney function and hemodynamics in pre-school children who underwent surgery for congenital heart disease (CHD). From 403 patients who had undergone surgery for CHD at least 6months before pre-school and were admitted to our hospital between 2011 and 2015, 75 who underwent blood and urine tests and cardiac catheterization were included in this study. The urinary albumin-to-creatinine ratio (ACR) was quantified, and the relationship of ACR with physical and laboratory findings and hemodynamics assessed using cardiac catheterization was analyzed. The study cohort was divided into three groups: Fontan group (n = 25), tetralogy of Fallot (TOF) group (n = 18), and control group (other biventricular CHDs; n = 32). The median age of patients was 5.9years. ACR was higher in the Fontan group than in the TOF and control groups (median: 15.0 vs. 5.0 and 0.0mg/g, p < 0.001). Moreover, albuminuria (ACR > 30mg/g) was observed in 20.0% of Fontan patients, while ACR was associated with potential complicating factors of Fontan circulation: high central venous pressure, high mean pulmonary artery pressure, and worse than moderate atrioventricular regurgitation. ACR showed a moderate correlation with the cystatin C-based estimated glomerular filtration rate (r = - 0.725, p < 0.001). Measurement of albuminuria in Fontan patients before they join elementary school is useful because it reflects kidney function and hemodynamic factors that can worsen their condition. Identification and management of patients with albuminuria may facilitate early therapeutic intervention for worsening Fontan factors, eventually delaying the deterioration of kidney function. A higher resolution version of the Graphical abstract is available as Supplementary information.

Effect of right anterolateral thoracotomy versus median sternotomy on postoperative wound tissue repair in patients with congenital heart disease: A meta-analysis.

Right anterolateral thoracotomy (RAT) and median sternotomy (MS) are two major methods for treatment of congenital cardiac disease. But there are various types of surgery that provide a better operative outcome for the patient. Therefore, we carried out a meta-analysis to investigate the effects of these two methods in the treatment of wound tissue, hospitalization and so on, to find out which surgery method could provide the best short-term effect. In this research, we chose an English controlled trial from 2003 to 2022 to evaluate the influence of right anterolateral thoracotomy and median sternotomy on the short-term outcome of Cardiopulmonary bypass (CPB), time of operation, time spent in the hospital, and the time of scar formation. Our findings suggest that the RAT method was associated with a shorter surgical scars for congenital heart disease operations compared to MS with respect to post-operation scars (WMD, 3.55; 95% CI, 0.04, 7.05; p = 0.05). The RAT method is better suited to the needs of patients who care about their injuries. Nevertheless, in addition to other surgery related factors which might affect post-operative wound healing, we discovered that MS took a shorter time to perform CPB compared with RAT surgery (WMD, - 1.94; 95% CI, -3.39, -0.48; p = 0.009). Likewise, when it comes to the time taken to perform surgery, MS needs less operational time compared to RAT methods (WMD, -12.84; 95% CI, -25.27, -0.42; p = 0.04). On the other hand, the time needed for MS to recover was much longer compared to the RAT (WMD, 0. 60; 95% CI, 0.02, 1.18; p = 0.04). This indicates that while RAT is advantageous in terms of shortening the duration of post-operative scar, it also increases the time needed for surgical operations and CPB.

A systematic review of early motor interventions for infants with congenital heart disease and open-heart surgery

BackgroundMotor development delay is the first neurodevelopmental impairment that becomes apparent in infants with congenital heart disease (CHD). Early interventions have addressed high-risk groups like infants born preterm, but little is known about interventions to improve motor outcome in CHD infants at risk of motor delay. The purpose of this review was to systematically review the literature on type and effect of motor intervention applied during the first year of life in infants with CHD following open-heart surgery.MethodsScoping searches were performed in May 2020 and April 2023 via MEDLINE, Embase, CINAHL, Cochrane, PsycINFO, PEDro, and Scopus. The review included studies published in English from 2015 to 2022. Primary outcome was infants’ motor development measured by standardized and non-standardized motor assessments, and if available, infants’ language and cognitive development, and any parental quality-of-life assessments as secondary outcomes. The studies’ quality was evaluated with a modified Newcastle-Ottawa scale.ResultsFour papers with low to high methodological quality met inclusion criteria. All studies investigated the influence of early physiotherapy. Four studies involved parents, and three studies used standardized tools to assess motor outcomes. No conclusion can be drawn about any positive effect of early motor interventions.ConclusionsEarly motor intervention in CHD infants may improve motor development; however, the few existing studies do not provide clear evidence. Thus, more prospective early intervention studies are needed.Trial registrationPROSPERO CRD42020200981.

A review of stem cell therapy in ischemic heart disease, where are we now?

Background: Regenerative therapies to rejuvenate the heart have a significant appeal for researchers. Preliminary findings from pre-clinical studies suggest that bone marrow cells may have reparative and regenerative effects on heart muscles, creating a ripe area for research. Many generations of stem cells used in pre-clinical and early clinical studies have shown promising but variable results. Objective: The current review article discusses the dilemmas in applying stem cell therapy to cardiovascular diseases and possible strategies to make it feasible. Methods: The field of regenerative therapies continued to progress with second-generation cells, third-generation cells, combination cell therapy, and the use of cell products alone. Research showed promising positive results in multiple randomized phases 1, 2, and 3 clinical trials in addition to numerous meta-analyses. The gaps in knowledge included stem-cell sources, their delivery routes, dosing, types of cells, and the indicated cardiac conditions. Results: The results from the latest randomized clinical trials, namely the Dream-HF, showed improved left ventricle function, symptoms, and overall survival. Studied patient populations include post-myocardial infarction (MI), ischemic/non-ischemic cardiomyopathy, intractable/microvascular angina, and cardiac surgery for congenital and valvular heart disease. The phase 3 DREAM-HF trial did not meet the primary heart failure endpoint of reducing hospital admission. Still, it showed a clinically significant reduction in major adverse cardiovascular events (MACE), including recurrent MI and stroke, by 60%. A 60% reduction in cardiovascular mortality and a 79% reduction in cardiovascular mortality in patients with evidence of inflammation (high CRP). The latter finding suggests a more anti-inflammatory effect. This effect was much higher than that observed in the PARADIGM-HF trial, which showed a 20% relative risk reduction in cardiovascular mortality. By combining the results of the DREAM-HF trial with MSC-HF, ixCELL-DCM, CONCERT-HF, and REGENERATE-DCM, the potential for clinical applications of cell therapy is promising. Conclusion: There is a promising role for cell therapy in the management of cardiovascular diseases. Results of trials in the setting of heart failure are more encouraging in both ischemic and non-ischemic cardiomyopathy. This is in contrast with acute myocardial infarction, where the results have been variable. Amongst all the various cell types tested MSCs show the most significant promise for treating HF.

Improving Outcomes for Infants After Cardiopulmonary Bypass Surgery for Congenital Heart Disease: A Commentary on Recent Randomized Controlled Trials.

Anesthesia management of patients undergoing thoracic endovascular aortic repair: A retrospective analysis of single center.

Thoracic endovascular aortic repair (TEVAR) is a new alternative surgical treatment for aortic pathologies, which is more minimally invasive. The aim of current study was to summarize the single-center experience of general anesthesia for patients undergoing TEVAR. In adult patients undergoing surgery for congenital heart disease, the strategy of "fast-track" anesthesia with early extubation in theater is associated with a shorter intensive care unit (ICU) stay, and lower health-care-related costs. Fast-track anesthesia has not been assessed in patients under TEVAR. Adult patients who received general anesthesia for TEVAR in our center from January 2020 to December 2020 were included. Baseline characteristics, airway management, anesthetic techniques and major complications were collected. A total of 204 (171 male, mean age 58.1 ± 11.5 years) patients met inclusion criteria for this study. The distribution of pathologies included 29 descending thoracic aneurysms, 87 type B dissections, and 88 intramural hematoma/perforating aortic ulcer. Etomidate was the induction agent in 190 (93.1%) patients, compared with propofol in 16 (7.8%). Cisatracurium was the muscle relaxant in 201 (98.5%), compared with rocuronium in 3 (1.5%). Midazolam (benzodiazepines) was given to 124 (60.8%) patients during anesthesia induction. General anesthesia was maintained with sevoflurane in 85.3% (174) patients, dexmedetomidine in 201 (98.5%) and propofol in 204 (100%). Postoperative length of stay (LOS) in the hospital was 6.0 (5.0-7.8) days. LOS in the ICU was 23.0 (20.0-27.8) hours. Overall neurologic event rate was 2.0% (n = 4) (spinal cord ischemia 1.5% [n = 3]; stroke 0.5% [n = 1]). After matching, patients who received "fast-track" anesthesia had a shorter LOS in ICUs (21.0 [18.0-24.0] vs 24.0 [20.0-44.0] hours; P = .005), and a shorter postoperative LOS in hospital (5.0 [4.0-7.0] vs 6.0 [5.0-8.0] days; P = .001). There were no in-hospital deaths. Fast-track anesthesia is feasible and safe in patients underwent TEVAR. This management strategy is associated with shorter LOS of ICU and total postoperative hospital stays. An early extubation strategy should be implemented for hemodynamically stable patients.

Association between regional oxygen saturation and central venous saturation in pediatric patients undergoing cardiac surgery: A prospective observational study.

We evaluated the correlation between regional oxygen saturation (rSO2 ) in the frontal and right renal dorsum (cerebral rSO2 and somatic rSO2 ) measured by near-infrared spectroscopy (INVOS™ 5100C, Medtronic) and central venous oxygen saturation (ScvO2 ) measured with a fiber-optic oximetry catheter (PediaSat™, Edwards Lifesciences) during surgery in order to determine whether noninvasive rSO2 could be used as an alternative to ScvO2 in pediatric cardiac surgery patients. We evaluated the correlation between regional tissue oxygen saturation (cerebral rSO2 and somatic rSO2 ) measured by near-infrared spectroscopy and other patient measures with central venous oxygen saturation (ScvO2 ) measured with a fiber-optic oximetry catheter to track global oxygen supply demand as a potential alternative or supplement to ScvO2 . This single-center prospective observational study enrolled 33 children (weight < 10 kg) who underwent cardiac surgery for congenital heart disease between February 2018 and November 2021. ScvO2 , cerebral rSO2 , and somatic rSO2 were recorded simultaneously after anesthesia induction and central venous catheter placement. Pearson's correlation coefficient and Bland-Altman analysis were used to determine the relationship between ScvO2 and rSO2 . We conducted correlation, Bland Altman, and multiple regression analyses to identify associations between rSO2 , patient measures, and ScvO2 values. The patients' median age was 11.0 (quartile 2.0-16.0) months. Their weight was 7.2 (quartile 4.5-9.2) kg. Cerebral rSO2 was significantly positively correlated with ScvO2 (r2 = 0.29, p = .002 in all patients; r2 = 0.61, p = .013 in the patients without mixing at the atrial level), whereas somatic rSO2 was not. The Bland-Altman analysis demonstrated biases [95% confidence interval; 95% CI] (lower and upper limits of agreement [95% CI]) of 0.27% [-4.26 to 4.80] (-24.79 [-32.61 to -16.96] to 25.33 [17.50 to 33.16]) between cerebral rSO2 and ScvO2 and 0.91% [-5.48 to 7.30] (-34.43 [-45.47 to -23.39] to 36.25 [25.21 to 47.29]) between somatic rSO2 and ScvO2 . Preoperative brain natriuretic peptide (BNP) and SpO2 were independent variables associated with ScvO2 and cerebral and somatic rSO2 . Cerebral rSO2 , SpO2 , and BNP were significantly correlated with ScvO2 , although the cerebral rSO2 correlation was greater for lesions without atrial mixing. rSO2 , BNP, and SpO2 might be used to track changes in ScvO2 but cerebral rSO2 is not sufficiently precise to replace it.

Neighborhood Childhood Opportunity, Race/Ethnicity, and Surgical Outcomes in Children With Congenital Heart Disease

BackgroundRacial and ethnic disparities in outcomes for children with congenital heart disease (CHD) coexist with disparities in educational, environmental, and economic opportunity. ObjectivesWe sought to determine the associations between childhood opportunity, race/ethnicity, and pediatric CHD surgery outcomes. MethodsPediatric Health Information System encounters aged <18 years from 2016 to 2022 with International Classification of Diseases-10th edition codes for CHD and cardiac surgery were linked to ZIP code-level Childhood Opportunity Index (COI), a score of neighborhood educational, environmental, and socioeconomic conditions. The associations of race/ethnicity and COI with in-hospital surgical death were modeled with generalized estimating equations and formal mediation analysis. Neonatal survival after discharge was modeled by Cox proportional hazards. ResultsOf 54,666 encounters at 47 centers, non-Hispanic Black (Black) (OR: 1.20; P = 0.01), Asian (OR: 1.75; P < 0.001), and Other (OR: 1.50; P < 0.001) groups had increased adjusted mortality vs non-Hispanic Whites. The lowest COI quintile had increased in-hospital mortality in unadjusted and partially adjusted models (OR: 1.29; P = 0.004), but not fully adjusted models (OR: 1.14; P = 0.13). COI partially mediated the effect of race/ethnicity on in-hospital mortality between 2.6% (P = 0.64) and 16.8% (P = 0.029), depending on model specification. In neonatal multivariable survival analysis (n = 13,987; median follow-up: 0.70 years), the lowest COI quintile had poorer survival (HR: 1.21; P = 0.04). ConclusionsChildren in the lowest COI quintile are at risk for poor outcomes after CHD surgery. Disproportionally increased mortality in Black, Asian, and Other populations may be partially mediated by COI. Targeted investment in low COI neighborhoods may improve outcomes after hospital discharge. Identification of unmeasured factors to explain persistent risk attributed to race/ethnicity is an important area of future exploration.

Neighborhood socioeconomic status and length of stay after congenital heart disease surgery.

Socioeconomic factors are associated with health outcomes and can affect postoperative length of stay after congenital heart disease (CHD) surgery. The hypothesis of this study is that patients from neighborhoods with a disadvantaged socioeconomic status (SES) have a prolonged length of hospital stay after CHD surgery. Pre- and postoperative data were collected on patients who underwent CHD surgery at the University of Maryland Medical Center between 2011 and 2019. A neighborhood SES score was calculated for each patient using data from the United States Census Bureau and patients were grouped by high vs. low SES neighborhoods. The difference of patient length of stay (LOS) from the Society for Thoracic Surgeons median LOS for that surgery was the primary outcome measure. Linear regression was performed to examine the association between the difference from the median LOS and SES, as well as other third variables. The difference from the median LOS was -4.8 vs. -2.2 days in high vs. low SES groups (p = 0.003). SES category was a significant predictor of LOS in unadjusted and adjusted regression analyses. There was a significant interaction between Norwood operation and SES-patients with a low neighborhood SES who underwent Norwood operation had a longer LOS, but there was no difference in LOS by SES in patients who underwent other operations. Neighborhood SES is a significant predictor of the LOS after congenital heart disease surgery. This effect was seen primarily in patients undergoing Norwood operation.

Congenital heart diseases with airway stenosis: a predictive nomogram to risk-stratify patients without airway intervention

BackgroundThis study focused on congenital heart disease (CHD) patients complicated with airway stenosis (AS) without airway intervention and aimed to identify the patients with potential risks.MethodsPatients diagnosed with CHD and AS were enrolled in this retrospective study. The primary outcome was defined as a postoperative mechanical ventilation duration of more than two weeks. We constructed a prediction model to predict the risk of prolonged mechanical ventilation (PMV).ResultsA total of 185 patients diagnosed with CHD and AS in Fuwai Hospital from July 2009 to December 2022 were included in the study. Weight at CHD surgery, cardiopulmonary bypass (CPB) duration, complex CHD and comorbid tracheobronchomalacia were identified as risk factors and included in the model. The ROC curve showed a good distinguishing ability, with an AUC of 0.847 (95% CI: 0.786–0.908). According to the optimal cut-off value of the ROC curve, patients were divided into high- and low-risk groups, and the subsequent analysis showed significant differences in peri-operative characteristics and in-hospital deaths.ConclusionsWith the predictive model, several factors could be used to assess the risky patients with PMV. More attention should be paid to these patients by early identification and routine surveillance.

Risk factors and early outcomes of chylothorax following congenital cardiac surgery: A single-center experience.

This study aims to investigate the incidence and risk factors for chylothorax and to evaluate the effect of chylothorax on the early postoperative outcomes following congenital cardiac surgery. A total of 1,053 patients (606 males, 447 females; median age: 12 months; range, 3 days to 48 years) who underwent surgery for congenital heart disease at our institute between January 2018 and December 2019 were retrospectively analyzed. Patients with chylothorax were identified and the data of this cohort was compared with the entire study population. Following the diagnosis of chylothorax, a standardized management protocol was applied to all patients. Of 1,053 patients operated, 78 (7.4%) were diagnosed with chylothorax. In the univariate analysis, younger age, peritoneal dialysis, preoperative need for mechanical ventilation, surgical complexity, delayed sternal closure, high vasoactive inotrope score in the first 24 h after operation, residual or additional cardiac lesions which required reoperations were found to be the risk factors for chylothorax (p<0.05). In the multivariate analysis, the correlation persisted with only younger age, infections, and peritoneal dialysis requirement (p<0.05). In the chylothorax group, ventilation times were longer, and re-intubation and infection rates were higher (p<0.05). Although the length of intensive care unit and hospital stay was significantly longer in this patient group, there was no significant association between the development of chylothorax and in-hospital mortality (p>0.05). Chylothorax following congenital cardiac surgery is a significant problem which prolongs the length of hospital stay and increases the infection rates. Complex cardiac pathologies which require surgery at early ages and re-operations are risk factors for chylothorax. Although there is no consensus on the most optimal therapeutic strategy, standardizing the management protocol may improve the results.

Trend of fetal echocardiography use and comparison of medical costs for congenital heart disease treatment based on fetal echocardiography use in a Korean single center.

The rate of the prenatal diagnosis of congenital heart disease is increasing along with advances in fetal echocardiography techniques. Here, we aimed to investigate the trend of the use of fetal echocardiography over time and to compare the medical costs of congenital heart disease treatment according to whether fetal echocardiography was performed. We reviewed our hospital's database, and patients who underwent the first surgery for congenital heart disease within 30 days of birth during 2005-2007, 2011-2013, and 2017-2019 were included. The severity of congenital heart disease diagnosed in each case was evaluated according to The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery Congenital Heart Surgery Mortality Scores (STS-EACTS Mortality Scores) and Mortality Categories (STAT Mortality Categories). In total, 375 patients were analyzed, and fetal echocardiography use increased significantly after the 2010s compared with in 2005-2007 (19.1% vs. 39%, p = 0.032 in Mortality Category 1-3; 15.5% vs. 69.5%, p = 0.000 in Mortality Category 4-5). Additionally, the mean STS-EACTS Mortality Score was higher in prenatally diagnosed patients than in postnatally diagnosed patients (2.287 vs. 1.787, p = 0.001). In the recent period, there was no significant difference in hospitalization durations and medical costs according to whether or not fetal echocardiography was performed. This single center study showed the use of fetal echocardiography is increasing. Further, prenatal diagnosis with fetal echocardiography causing no differences in medical costs in recent years. Therefore, we suggest that fetal echocardiography can be applied more widely without increasing the economic burden.
