Cardiac Catheterization in Adults with Ebstein Anomaly: Pathophysiologic Insights Regarding Surgical Repair and Prognosis
AbstractThe underlying invasive hemodynamics and physiology in Ebstein anomaly (EA) are poorly understood. Moreover, the hemodynamic impact of tricuspid valve intervention in EA has not been well studied. Retrospective cohort of 52 adults with repaired and 36 with unrepaired EA undergoing right heart catheterization at Mayo Clinic, MN between 1993 and 2021. “Repaired” EA was defined as prior tricuspid valve repair and/or replacement (83% post-tricuspid valve replacement). Repaired patients were younger than those with unrepaired EA (41.3 ± 16.0 versus 50.6 ± 15.6 years,p = 0.008) and had a lower prevalen...

Association of Prenatally Diagnosed Isolated Single Left Superior Vena Cava and Postnatal Development of Coarctation of the Aorta
AbstractTo report the prevalence of coarctation of the aorta (CoA) in fetuses with single left superior vena cava (SL-SVC) and to evaluate changes in echocardiographic measurements. Additionally, to report the prevalence of associated malformations. Retrospective observational study of fetuses diagnosed with SL-SVC between 2012 and 2021 at a tertiary fetal cardiology unit. In fetuses without intracardiac abnormalities, Z-scores of the ventricles, great arteries, and Doppler flow patterns are reported. We identified 47 fetuses with SL-SVC of which 8/47 (17%) had abnormal intracardiac anatomy. One fetus was lost to follow-up...

Longitudinal Cardiac Evaluation of Children with Multisystem Inflammatory Syndrome (MIS-C) Following COVID-19 by Conventional and Speckle-Tracking Echocardiography
In conclusion, in the acute and follow-up phase, we detected abnormal LV-GLS values in some patients, in the presence of normal LVEF, indicating that STE-GLS is a valuable tool for identifying subclinical myocardial injury in MIS-C. (Source: Pediatric Cardiology)

Right Ventricular and Outflow Tract Functional Characteristics After Repair of Tetralogy of Fallot with Major Aortopulmonary Collaterals
This study describes right ventricle (RV) characteristics and right ventricle to pulmonary artery (RV-PA) conduit function pre- and post-repair in patients with tetraology of Fallot with major aortopulmonary collaterals (TOF/MAPCAs). We reviewed patients who underwent single-stage, complete unifocalization, and repair of TOF/MAPCAs between 2006 and 2019 with available pre- and early postoperative echocardiograms. For a subset of patients, 6 –12 month follow-up echocardiogram was available. RV and left ventricle (LV) characteristics and RV-PA conduit function were reviewed. Wilcoxon signed rank test and McNemar’s test ...

Predictive Value of Myocardial Markers for Early Postoperative Mortality in Children with Congenital Heart Disease
AbstractTo investigate the influencing factors of postoperative creatine kinase-MB (CK-MB) elevation in children with congenital heart disease and its peak value in predicting early postoperative mortality. The clinical data of 521 children with congenital heart disease under the age of 14 who underwent elective surgery in Beijing Children ’s Hospital from December 2018 to December 2020 were retrospectively analyzed. Stepwise multiple linear regression was used to analyze independent risk factors for postoperative CK-MB elevation, receiver operating characteristic (ROC) curve was used to determine the predictive value of...

Early and Long-Term Clinical Outcomes of Ductal Stenting Versus Surgical Aortopulmonary Shunt Among Young Infants with Duct-Dependent Pulmonary Circulation
AbstractSurgical aortopulmonary shunting (SAPS) and ductal stenting (DS) are the main palliations in infants with cyanotic congenital heart diseases (CHD). We aimed to study the safety and efficacy of DS and to compare it with SAPS as a palliative procedure in infants with CHD and duct-dependent pulmonary circulation. Retrospective institutional clinical data review of consecutive infants aged  <  3 months who underwent DS or SAPS over 5 years. The primary outcome was procedural success which was defined as event-free survival (mortality, need for re-intervention, procedural failure) at 30 days post-procedure. Th...

Feeding Practices in Infants with Hematochezia and Necrotizing Enterocolitis on Acute Care Cardiology Units
AbstractInfants with congenital heart disease (CHD) are at risk for developing both benign hematochezia and necrotizing enterocolitis (NEC). Despite these risks there are very few studies that investigate modifiable risk factors such as feeding practices. It remains unclear what feeding practices should be avoided due to higher incidence of CHD-NEC. We aim to assess the feeding practices across three high volume tertiary centers to establish a relationship between various feeding practices and development of NEC. A multicenter retrospective review of feeding practices at the time of documented hematochezia event that occur...

Single-Chamber and Dual-Chamber Pacemaker Devices in Adults with Moderate and Complex Congenital Heart Disease: A Single Tertiary Referral Center Experience
AbstractThe number of device implantation procedures has increased in adult patients with congenital heart disease (ACHD). Despite significant improvements in materials and implantation techniques, these patients are exposed to higher risk of device related complications than general population. Herein, we describe our single tertiary referral center experience on transvenous pacemaker (PM) implantation and follow-up in adult patients with moderate and complex congenital heart disease (CHD) as limited data are available on long-term outcome. We considered all adults with moderate and complex CHD aged more than 16 years who...

Evaluation of the Left Ventricular Myocardium Using Layer-Specific Strain Analysis in Adolescent Athletes Performing High-Intensity Interval Training
The objective of this study was to evaluate the impact of HIIT on the myocardial function of adolescent athletes, specifically focusing on left ventricular (LV) function, using conventional echocardiography and layer-specific strain (LSS) analysis. A total of 19 male adolescent athletes (with mean age of 16.83  ± 1.29 years) participating in various football clubs were recruited for this study. During the course of 8 weeks, these adolescent male athletes engaged in HIIT program centered around running. Upon completion of HIIT program, a treadmill exercise test was conducted. Subsequently, conventio nal and LSS echoc...

Predictors of Atrial Arrhythmia in Adults with Repaired Tetralogy of Fallot
AbstractTetralogy of Fallot (TOF), the most common cyanotic congenital heart disease in adults, has excellent long-term survival. However, many patients (30 –45%) develop late arrhythmias. Previous studies have identified predictors of arrhythmia (atrial or ventricular) using clinical markers that predate arrhythmia onset by many years. Our objective was to develop a predictive model for incident atrial arrhythmias within two years of clinical evaluat ion and diagnostic testing. A single-center nested unmatched case-control study of 174 adults with repaired TOF. We included only patients with results from ECG and echocar...
