Congenital Heart Disease

OBJECTIVE: The objective of this study was to analyze if the addition of simple cardiac scan in cases with increased nuchal translucency (NT) and/or abnormal ductus venosus (DV) blood flow, and/or tricuspid regurgitation (TCR) can improve detection of congenital heart defects (CHD) in chromosomally normal fetuses without non-cardiac defects at 11-13 + 6 gestational weeks in a population of singleton pregnancies. METHODS: During the 10 years period, all singleton pregnancies at 11-13 + 6 weeks were routinely scanned for NT, DV blood flow and TCR assessment and, if a single of these parameters was abnormal, simple cardiac scan with 2D gray scale and color and/or directional power Doppler in 4-chamber (4-CV) and 3 vessel and trachea views (3VTV) was performed...

OBJECTIVE: Adult congenital heart disease (ACHD) patients are at risk of sudden cardiac death (SCD). However, methods for risk stratification are not yet well-defined. The Tpeak -Tend (TpTe) interval, a measure of dispersion of ventricular repolarization, is a risk factor for SCD in non-ACHD patients. We aim to evaluate whether TpTe can be used in risk stratification for SCD in ACHD patients. DESIGN: From an international multicenter cohort of 25 790 ACHD patients, we identified all SCD cases...

INTRODUCTION: Mechanisms and risk factors for cerebrovascular accidents (CVAs) in Ebstein's anomaly (EA) are not well understood; hence, we aimed to clarify these in a large cohort of EA patients. METHODS: Patients with a confirmed diagnosis of EA were retrospectively reviewed. Baseline characteristics were compared between patients with and without a prior history of CVA using logistic regression modeling. Cox regression analysis was used to identify predictors of CVA following initial evaluation...

OBJECTIVE: Three scores have been proposed to stratify the risk of mortality for each cardiac surgical procedure: The RACHS-1, the Aristotle Basic Complexity (ABC), and the STS-EACTS complexity scoring model. The aim was to compare the ability to predict mortality and morbidity of the three scores applied to a specific population. DESIGN: Retrospective, descriptive study. SETTING: Pediatric and neonatal intensive care units in a referral hospital...

Left main coronary artery ostial atresia (LMCAOA) is a rare congenital anomaly of the coronary arteries. The published literature regarding the current diagnostic and management recommendations are limited. We present three case series of LMCAOA from our institution, including one with a unique association with anomalous origin of left coronary artery (LCA) from pulmonary artery. In addition, this report includes a review of 50 pediatric and 43 adult cases from literature. The majority of the patients were symptomatic...

OBJECTIVES: We sought to evaluate the safety and efficacy in improving cardiac function and functional capacity with device closure of large atrial septal defects (ASD) in senior adults. BACKGROUND: Atrial septal defect accounts for about 10% of all congenital heart disease. It still remains unclear whether large ASD closure in senior people should be performed or not. Hence we aim to prospectively assess the safety and clinical status of senior patients after transcatheter closure in large ASD...

OBJECTIVE: The main goal of this study is to examine the variation in vasoactive agent prescription patterns across a large cohort of patients. In addition, we sought to determine the association between the number of vasoactive agents used during admissions and characteristics of admissions utilizing varying numbers of vasoactive agents. METHODS: This was a multi-institutional, cross-sectional study of the pediatric health information system database of patients who underwent congenital heart surgery and received vasoactive agents from 2004 to 2015...

OBJECTIVE AND PATIENTS: This study aimed to characterize bone mineral density abnormalities and pathophysiological associations in young adults living with a Fontan circulation. DESIGN: Participants underwent bone mineral density measurement using dual-energy X-ray absorptiometry and serum biochemical analysis, cardiopulmonary exercise and strength testing and transthoracic echocardiography. RESULTS: In our cohort (n = 28), 29% had osteopenic-range bone mineral density and one patient was osteoporotic (average hip t score: -0...

BACKGROUND: Children with hypoplastic left heart syndrome (HLHS) have risk for mortality and/or transplantation. Previous studies have associated right ventricular (RV) indices in a single echocardiogram with survival, but none have related serial measurements to outcomes. This study sought to determine whether the trajectory of RV indices in the first year of life was associated with transplant-free survival to stage 3 palliation (S3P). METHODS: HLHS patients at a single center who underwent stage 1 palliation (S1P) between 2000 and 2015 were reviewed...

OBJECTIVE: Atrial arrhythmias and atrioventricular valve regurgitation (AVVR) are common causes of morbidity among adults with congenital heart disease (ACHD). The impact of rhythm control on AVVR in this population is unknown. We sought to determine whether a rhythm control strategy is associated with greater freedom from AV valve surgery than a rate control strategy. DESIGN: Patients evaluated by both ACHD and electrophysiology specialists at a single academic center were screened for atrial arrhythmias and at least moderate-severe AVVR...

OBJECTIVE: To investigate the impact of feeding mode on neurodevelopmental outcomes in children with congenital heart defects. DESIGN: A retrospective cohort study of 208 children with congenital heart disease (CHD), who had surgery from 1 January 2013 until 31 December 2016 at Texas Children's Hospital, Houston, TX, US. SETTINGS: University Hospital, Developmental Outcome Clinic. OUTCOMES MEASURES: Standardized cognitive scores were assessed with Capute Scales and motor development with Revised Gesell Developmental Schedules...

BACKGROUND & AIMS: Fontan surgery for single ventricle congenital heart disease leads to Fontan-associated liver disease (FALD). Typical laboratory tests, imaging, and histopathology cannot predict clinical severity in FALD. HepQuant SHUNT is a proprietary serum test of hepatic function and physiology that has not yet been evaluated in FALD. METHODS: Fourteen adult FALD patients at a single urban tertiary care center who underwent a Fontan procedure in childhood received HepQuant SHUNT testing between September 2015 and April 2018...

BACKGROUND: Hypoxia is a common and sometimes severe morbidity of single ventricle congenital heart disease (CHD). Creation of an arteriovenous fistula (AVF) is occasionally performed for patients after superior or total cavopulmonary connection (SCPC or TCPC) in an attempt to improve oxygen saturations. Despite previous reports, AVF creation is a rare palliation with inadequately defined benefits and risks. We sought to determine changes in peripheral oxygen saturation (SpO2 ) and risk of adverse event after AVF creation in children with single ventricle CHD at our institution...

OBJECTIVE: Evaluate long-term outcomes following balloon pulmonary valvuloplasty (BPV) for pulmonary stenosis (PS). BACKGROUND: Long-term data following BPV is limited to small, single center studies. METHODS: BPV from April 12, 1985 to January 7, 2015 from three centers were included. Outcomes studied were ≥ moderate PI by echocardiogram and residual PS ≥ 40 mm Hg. Risk factors for ≥ moderate PI, residual PS, and repeat intervention were assessed by univariate and multivariate analysis...

BACKGROUND: Left cardiac sympathetic denervation (LCSD) has been proposed as useful therapy for long QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia (CPVT), in addition to anti-arrhythmic agents and implantable cardioverter defibrillators. This study aimed to assess the current evidence for LCSD and compare the open vs the video-assisted thoracoscopic surgery (VATS) approaches. METHODS: MEDLINE, Embase and Cochrane library databases were searched up to December 2018 for studies reporting the long-term outcomes of LCSD in LQTS, CPVT patients...

AIMS: Age-related cardiovascular diseases are a relevant risk in the aging population of adults with congenital heart diseases (ACHD). Risk factors such as the metabolic syndrome (MetS) impact the risk of increased carotid intima-media thickness (cIMT) and thereby long-term cardiovascular diseases. The aim of the study was to assess MetS in ACHD and outline a possible association to cIMT. METHODS AND RESULTS: In total, 512 ACHD (43.0 ± 9.6 years, 48.9% female) were screened for MetS by the standards of the International Diabetes Federation, and their cIMT by ultrasound from January 2017 to June 2019...

Pharmacologic stress cardiovascular magnetic resonance (PSCMR) is a well-established and reliable diagnostic tool for evaluation of coronary artery disease in the adult population. Stress imaging overall and PSCMR in particular is less utilized in the pediatric population with limited reported data. In this review, we highlight the potential use of PSCMR in specific pediatric cohorts with congenital and acquired heart disease, and we review the reported experience. A suggested protocol is presented in addition to two case examples of patients with Kawasaki disease where PSCMR aided decision making...

OBJECTIVE: Deciding on a surgical pathway for neonates with ≥2 left heart obstructive lesions is complex. Predictors of the successful biventricular (2V) repair in these patients are poorly defined. The goal of our study was to identify patients who underwent the 2V repair and assess anatomic and echocardiographic predictors of success. DESIGN: Infants born between July 2015 and August 2017 with ≥2 left heart obstructive lesions with no prior interventions were identified (n = 19)...

OBJECTIVE: As adults with congenital heart disease (CHD) grow older, preoperative screening for coronary artery disease (CAD) may be indicated prior to CHD surgery. Data regarding the indications for preoperative CAD screening in this population are limited. Current practice is to follow guidelines for patients with valvular heart disease; however, the risk for CAD in certain congenital heart diagnoses may be higher than the general population. This study aimed to assess the results of preoperative CAD screening in patients prior to CHD surgery...

Three-dimensional rotational angiography (3D-RA) enables volumetric imaging through rotation of the C-arm of an angiographic system and real-time 3D reconstruction during cardiac catheterization procedures. In the field of congenital heart disease (CHD), 3D-RA has gained considerable traction, owing to its capability for enhanced visualization of spatial relationships in complex cardiac morphologies and real time image guidance in an intricate interventional environment. This review provides an overview of the current applications, strengths, and limitations of 3D-RA acquisition in the management of CHD and potential future directions...
