With the improvement in the detection of congenital heart disease in fetal life, fetal cardiac interventions are pushing the envelope in hopes of either altering the natural history of disease or improving survival in certain high-risk lesions. These interventions include fetal aortic valvuloplasty for evolving hypoplastic left heart syndrome, fetal atrial septoplasty with or without atrial septal stenting for hypoplastic left heart syndrome and variants with intact or severely restrictive atrial septum, and fetal pulmonary valvuloplasty for severe pulmonary stenosis or pulmonary atresia with intact ventricular septum. This review discusses their indications, technical aspects, and outcomes based on available literature. [ABSTRACT FROM AUTHOR]

Background: As pediatric implantable cardioverter‐defibrillator (ICD) utilization increases, hospital admission rates will increase. Data regarding hospitalizations among pediatric patients with ICDs are lacking. In addition, hospital mortality rates are unknown. This study aimed to evaluate (1) trends in hospitalization rates from 2000 to 2016, (2) hospital mortality, and (3) factors associated with hospital mortality among pediatric admissions with ICDs. Methods: The Kids' Inpatient Database (2000, 2003, 2006, 2009, 2012, 2016) was used to identify all hospitalizations with an existing ICD ≤20 years of age. ICD9/10 codes were used to stratify admissions by underlying diagnostic category as: (1) congenital heart disease (CHD), (2) primary arrhythmia, (3) primary cardiomyopathy, or (4) other. Trends were analyzed using linear regression. Hospital and patient characteristics among hospital deaths were compared to those surviving to discharge using mixed multivariable logistic regression, accounting for hospital clustering. Results: Of 42 570 716 hospitalizations, 4165 were admitted ≤20 years with an ICD. ICD hospitalizations increased four‐fold (p =.002) between 2000 and 2016. Hospital death occurred in 54 (1.3%). In multivariable analysis, cardiomyopathy (odds ratio [OR]: 3.5, 95% confidence interval [CI]: 1.1–11.2, p =.04) and CHD (OR: 4.8, 95% CI: 1.5–15.6, p =.01) were significantly associated with mortality. In further exploratory multivariable analysis incorporating a coexisting diagnosis of heart failure, only the presence of heart failure remained associated with mortality (OR: 8.6, 95% CI: 3.7–20.0, p <.0001). Conclusions: Pediatric ICD hospitalizations are increasing over time and hospital mortality is low (1.3%). Hospital mortality is associated with cardiomyopathy or CHD; however, the underlying driver for in‐hospital death may be heart failure. [ABSTRACT FROM AUTHOR]

Congenital heart disease (CHD) may cause a significant comorbidity in patients with Turner syndrome. The commonly reported CHD in these patients includes bicuspid aortic valve and coarctation of the aorta. Left ventricular noncompaction (LVNC) is a rare form of cardiomyopathy that has been reported in literature only three times in adult patients with Turner syndrome. We report the first case of a 6-year-old asymptomatic female with Turner syndrome who was referred for cardiac evaluation after her Turner syndrome diagnosis. Echocardiogram was suspicious for LVNC, which was confirmed on cardiac magnetic resonance imaging. [ABSTRACT FROM AUTHOR]

Right ventricular (RV) hypoplasia may develop secondary to pulmonary or tricuspid valve atresia. These patients are usually symptomatic early in life and need prompt intervention. Isolated RV hypoplasia is a rare congenital heart disease. We report a case of 23-year-old twins who have been monitored for the last 14 years for isolated right ventricular hypoplasia. ECHO and MRI studies showed a small, heavily trabeculated, nonapex-forming RV and mild tricuspid valve insufficiency. The girl has a patent foramen ovale (PFO). Otherwise, the cardiac anatomy and function was normal. They have both been completely asymptomatic from the cardiac standpoint. The family history is remarkable for death of father at the age of 30 years with autopsy suggestive of a hypoplastic RV. The paternal uncle also died at the age of 46 years, and his son has an unidentified congenital heart disease. The family history appears to suggest an autosomal dominant pattern of inheritance with variable expressivity. However, the chromosome microarray analysis of the twins did not identify any variations of clinical significance. [ABSTRACT FROM AUTHOR]
