Abstract This work aimed to predict postoperative knee functions of a new patient prior to total knee arthroplasty (TKA) surgery using machine learning, because such prediction is essential for surgical planning and for patients to better understand the TKA outcome. However, the main difficulty is to determine the relationships among individual varieties of preoperative and postoperative knee kinematics. The problem was solved by constructing predictive models from the knee kinematics data of 35 osteoarthritis patients, operated by posterior stabilized implant, based on generalized linear regression (GLR) analysis. Two prediction methods (without and with principal component analysis followed by GLR) along with… More >

Abstract Background: In an effort to reduce postoperative trauma and achieve more cosmetic results, minimally invasive approaches to correct congenital heart anomalies have been recently proposed and increasingly adopted. Here we describe our experience for the past 23 years. Methods: Patients who underwent a surgical procedure between February 1996 and March 2019 with a minimally invasive approach for the correction of congenital heart disease in our center were included in this study. A statistical analysis was carried out to compare the results of the different minimally invasive techniques. A meta-analysis was conducted to compare our results in patients undergoing atrial septal… More >

Abstract Background: Left-to-right shunt in sinus venosus septal defect (SVSD) may affect resistive (pulmonary vascular resistance–PVR) and elastic (pulmonary artery compliance-PAC) pulmonary artery properties. This study aimed at evaluating (1) impact of age, (2) pulmonary hemodynamics, and (3) outcome in a large cohort of SVSD patients. Methods: This study included 136 patients with SVSD (median age at diagnosis 14 (IQR 5–48) years, 47% male) of which 87 underwent catheterization. Pressures were measured and cardiac output was evaluated using the Fick principle at diagnosis. PVR, PAC and their product (RC time) were calculated. Results: Surgical repair was performed in 128 (94%) at… More >

Abstract Background: Predicting the probability for sudden cardiac death (SCD) and thus evaluation of patients for electrical device therapy and/or ablation is one of the main tasks in clinics for adults with congenital heart disease (ACHD) following repaired tetralogy of Fallot (rTOF) patients. Previous data suggests that QRS complex analysis can help identifying those patients who subsequently suffer from SCD. We hypothesized that a long QRS duration is associated with adverse rhythm events if caused by conduction abnormalities but not if caused by right ventricular remodeling. Methods: A retrospective analysis was performed entailing all rTOF patients who were seen at our… More >

Abstract Background: There is limited information on outcomes of adult patients with pulmonary atresia with intact ventricular septum (PA-IVS) due to the low incidence of disease and the large variation of surgical histories. Methods: Among 58 patients with repaired PA-IVS, a total of 32 patients aged ≥16 years and who were followed at our institution between January 2003 and December 2018 were reviewed. Surgical history, clinical outcomes, and laboratory, echocardiographic and electrocardiographic data were obtained by chart review. Results: Follow-up was from the age of 16 years and the median age at the latest follow-up was 23.7 years. Twenty-four patients had… More >

Abstract Background: In pediatric cardiac care, many centers participate in multiple, national, domain‐specific registries, as a major component of their quality assessment and im‐ provement efforts. Small cardiac programs, whose clinical activities and scale may not be well‐suited to this approach, need alternative methods to assess and track quality.
Methods: We conceived of and piloted a rapid‐approach cardiac quality assessment, intended to encompass multiple aspects of the service line, in a low‐volume program. The assessment incorporated previously identified measures, drawn from multiple sources, and ultimately relied on retrospective chart review.
Results: A collaborative, multidisciplinary team formed and came to consensus on… More >

Abstract Objective: Various options exist for right ventricular outflow tract (RVOT) recon‐ struction in congenital heart disease. The Freestyle porcine aortic root may be used but its longevity is not well defined.
Design: We performed a retrospective review of all non‐Ross RVOT reconstructions using the Freestyle root in our institution. Survival and reintervention, either by sur‐ gery, transcatheter valve implantation, balloon valvuloplasty, or bare metal stent placement, were recorded. Factors associated with reintervention were assessed using Cox regression.
Results: Between January 2002 and December 2015, there were 182 patients identi‐ fied. Sixteen patients were lost to follow‐up and 3 patients died,… More >

Abstract Background: The increasing number of patients with Ebstein anomaly (EA) surviving into adulthood implies improvements in the treatments for the complex lesion. We revisited the clinical outcomes of patients with EA to demonstrate their “real world” survival.
Objectives: To identify the survival and predictors of mortality in patients with EA who underwent medical or surgical management in the present era.
Methods: All patients who had EA with atrioventricular concordance between 1994 and 2016 were retrospectively reviewed. Baseline characteristics, initial echocardio‐ graphic findings, treatments, and outcomes were explored. The survival analysis was performed at the end of 2017. A multivariate analysis… More >

Abstract Congenital heart disease (CHD) is present in approximately 50% of patients with trisomy 21 (T21) and Turner syndrome (TS). According to the American Academy of Pediatrics, every patient with these genetic disorders should have a postnatal echocardiogram. T21 is usually associated with atrioventricular (30%–60%), atrial (16%-21%), or ventricular septal defects (14%–27%). TS is usually associated with left-sided heart disease. However, the spectrum of CHD in these genetic disorders is wider than those mentioned lesions. More cardiac surgical procedures are offered to these patients and that has influenced positively their life expectancy for some CHD conditions. Single ventricular anatomy is associated… More >

Abstract Objectives: Mortality associated with the modified Blalock–Taussig shunt (MBTS) remains high despite advanced perioperative management. This study was formulated to provide data on (1) current indications, (2) outcomes, and (3) factors affecting mortality and morbidity.
Design: A retrospective single center chart review identified 95 children (excluding hypoplastic left heart lesions) requiring a MBTS. Mortality and major morbidity were analyzed using the Kaplan Meier method and risk factor analysis using Cox’s proportional hazard regression.
Results: Median age was 8 (0–126) days, weight 3.1(1.7–5.4) kg. Seventy-three percent were neonates, 58% duct dependent and 73% had single ventricle physiology. Ninety-seven percent had a… More >
