AIMS: Supraventricular arrhythmias are a major cause of morbidity and mortality in adult patients with congenital heart disease (CHD). Intraoperative ablation offers an alternative for patients who failed ablation procedures or are requiring concomitant surgical intervention. We present our long-term results with the surgical treatment of arrhythmias in adults with CHD (ACHD) undergoing elective cardiac surgery and the clinical predictors for arrhythmia recurrence. METHODS AND RESULTS: Between 2002 and 2013, 80 consecutive patients with CHD, mean age of 39 years, underwent intraoperative ablation with monopolar irrigated radiofrequency during cardiac surgery procedures...

OBJECTIVE: Studies in children with heart disease have been hampered by a lack of easily identifiable patient groups. Currently, there are few prospective population-based registries covering the entire spectrum of heart disease in children. KinCor is a Dutch national registry for children with heart diseases. This paper presents the aims, design and interim results of the KinCor project. METHODS: All children presenting at a Dutch university medical centre with a diagnosis of heart disease from 2012 onwards were eligible for registration in the KinCor database...

BACKGROUND: Pathophysiologic changes in children with congenital heart disease may alter the effect of drugs by influencing the pharmacokinetics (PK). Considering the limited literature that describes the PK of etomidate in pediatric patients, especially in those with tetralogy of Fallot (TOF), our aim was to characterize the PK of etomidate and explore the effects of TOF. METHODS: Twenty-nine pediatric patients (15 with TOF and 14 with normal cardiac anatomy) scheduled to undergo elective surgery under general anesthesia were recruited in the study...

The population of adults with tetralogy of Fallot (TOF) is growing, and it is not known how the changes in age distribution, treatment strategies, and prevalence of co-morbidities impact their interaction with the health care system. We sought to analyze the frequency and reasons for hospital admissions over the past decade. We extracted serial cross-sectional data from the United States Nationwide Inpatient Sample on hospitalizations including the diagnostic code for TOF from 2000 to 2011. From 2000 to 2011, there were 20,545 admissions for subjects with TOF, with a steady increase in annual number...

BACKGROUND: Cardiac operations in high-risk adult congenital heart disease (ACHD) patients may require mechanical circulatory support (MCS), such as extracorporeal membrane oxygenation (ECMO) or intraaortic balloon pump (IABP), to allow the cardiopulmonary system to recover. METHODS: We reviewed records for all ACHD patients who required MCS following cardiotomy at our institution from 1/2001 to 12/2013. RESULTS: During the study period, 2264 (mean age 39...

More than 50% of children who undergo repair of tetralogy of Fallot (TOF) using a transannular patch will require pulmonary valve replacement (PVR) in early adulthood. The premise of PVR in this setting is to ameliorate the relentless right ventricular (RV) dilatation that otherwise occurs in the presence of severe pulmonary regurgitation. Severe RV dilatation is associated with RV dysfunction, symptoms of exercise intolerance, tricuspid regurgitation and-occasionally-life-threatening RV failure or dangerous ventricular tachyarrhythmia...

Left ventricular (LV) ejection fraction (EF) and right ventricular (RV) ejection fraction by cardiovascular magnetic resonance (CMR) are associated with functional health status in patients with repaired tetralogy of Fallot (TOF) in cross-sectional studies, but few longitudinal data are available. This study aimed to determine predictors of subsequent decrease in functional health status in midterm follow-up. Patients with repaired TOF who had previously completed CMR and assessment with the Short Form 36 version 2 (SF-36) were recruited for repeat CMR, SF-36, and exercise test, if they had not had interval pulmonary valve replacement (PVR)...

BACKGROUND: The postnatal development of myofibrillar mechanics, a major determinant of heart function, is unknown in pediatric patients with tetralogy of Fallot and related structural heart defects. We therefore determined the mechanical properties of myofibrils isolated from right ventricular tissue samples from such patients in relation to the developmental changes of the isoforms expression pattern of key sarcomere proteins involved in the contractile process. METHODS AND RESULTS: Tissue samples from the infundibulum obtained during surgery from 25 patients (age range 15 days to 11 years, median 7 months) were split into half for mechanical investigations and expression analysis of titin, myosin heavy and light chain 1, troponin-T, and troponin-I...

BACKGROUND: Sudden death of presumed arrhythmic etiology is the leading cause of mortality in adults with tetralogy of Fallot. OBJECTIVES: To assess the impact of exercise on ventricular arrhythmias in adults with tetralogy of Fallot. METHODS: Adults with repaired tetralogy of Fallot were randomized in a 2:1 ratio to an open-label trial of standard care versus 12weeks of supervised combined aerobic/resistance training with continuous Holter monitoring...

Residual right ventricular outflow tract and pulmonary valve disease is common in adults with repaired tetralogy of Fallot. Chronic severe pulmonary regurgitation as a result of surgical repair can lead to myriad complications including right ventricular dysfunction, decreased exercise tolerance, right heart failure and symptomatic arrhythmias. The aim of restoring pulmonary valve integrity is to preserve right ventricular size and function with the intent of mitigating the development of symptoms and poor long-term outcomes...

Parameters from cardiopulmonary exercise test (CPET) are useful prognostic factors for patients with repaired tetralogy of fallot (TOF). Its application in exercise prescription remains unclear. This study sought to define its role. We made current exercise recommendations in repaired TOF patients according to European Society of Cardiology (ESC) guideline, which were based on ventricular function, pressure/volume load, pulmonary artery pressure, hypoxemia and arrhythmic burden both at rest and during exercise...
