Sudden death occurs in patients after repair of congenital heart disease. In those with tetralogy of Fallot, or a similar lesion, ventricular tachycardia has been hypothesized as the major arrhythmic mechanism for sudden death. It would be desirable to identify individuals at risk for sudden death, to determine which arrhythmia would be likely to cause sudden death, and to treat those individuals with an appropriate antiarrhythmic to prevent sudden death. For the last 10 years, physicians have been treating patients with antiarrhythmic drugs, based on a number of criteria, the most common of which is the presence of premature ventricular contractions.1,2 The practice has recently been called into question by the CAST trial. It is the purpose of this paper to review the evidence that repair causes ventricular arrhythmias, that ventricular arrhythmias cause sudden death, and that ventricular arrhythmias should be treated prophylactically.

Ventricular arrhythmias are common in all forms of heart disease and are an important cause of cardiac arrest and sudden death. Many ventricular arrhythmias are benign but may serve as a marker for underlying disease or its severity. Others are life threatening. The significance of an arrhythmia is determined by the specific characteristics of the arrhythmia and the associated heart disease, and these features guide evaluation and therapy. This review discusses various mechanisms and types of ventricular arrhythmias and management based on clinical presentation (including patients with symptomatic arrhythmia and increased risk of sudden death without arrhythmia symptoms). Genetic arrhythmia syndromes, such as abnormalities of repolarization and the QT interval, catecholaminergic polymorphic ventricular tachycardia (VT), and inherited cardiomyopathies, are discussed in depth. Under the rubric of management of ventricular arrhythmias, drug therapy for ventricular arrhythmias, implantable cardioverter-defibrillators (ICDs), and catheter ablation for VT are also covered. Tables chart out guideline recommendations for ICD therapy, drugs for the management of ventricular arrhythmias, and indications and contraindications for catheter ablation of ventricular arrhythmias. Electrocardiograms are provided, as well as management algorithms for ventricular arrhythmias based on patient presentation, and an algorithm for identifying patients with systolic heart failure and left ventricular ejection less than or equal to 35% who are candidates for consideration of an ICD for primary prevention of sudden cardiac death. This review contains 5 figures, 8 tables, and 61 references.

AbstractBackgroundRepairing cyanotic congenital heart disease may be associated with preserving endothelial function. The present study aimed to evaluate vascular endothelial function in patients with repaired cyanotic congenital heart disease.MethodsIn a case–control study conducted in 2012 in Isfahan, Iran, 42 consecutive patients aged <35 years who had suffered from different types of cyanotic congenital heart disease and had undergone complete repair of their congenital heart defect were assessed in regard to their endothelial function state by measuring flow-mediated dilatation and other cardiac function indices. They were paired with 42 sex- and age-matched healthy controls.ResultsThe mean flow-mediated dilatation was lower in patients with repaired cyanotic congenital heart disease than in the controls [6.14±2.78 versus 8.16±1.49 respectively (p<0.001)]. Significant adverse correlations were found between flow-mediated dilatation, age, and body mass indexes, in those who underwent repair surgery. In addition, flow-mediated dilatation had a positive association with the shortening fraction, ejection fraction, and tricuspid annular plane systolic excursion value, and it was also inversely associated with carotid intima-media thickness and the myocardial performance index. The mean of the flow-mediated dilatation was significantly higher in the group with tetralogy of Fallot along with complete repair before the age of 2.5 years and also in those patients with total anomalous pulmonary venous connection or transposition of the great arteries repaired with an arterial switch operation before 6 months of age, compared with the other two subgroups. This includes patients with a tetralogy of Fallot defect repaired after 4 years of age and those with complex cyanotic congenital heart disease that was repaired after 2.5 years of age (mean age at repair 9±6.1 years).ConclusionEarly repair of a cyanotic defect can result in the protection of vascular endothelial function and prevent the occurrence of vascular accidents at an older age.

Background Major achievements in congenital heart disease (CHD) treatment over the past 20 years have altered the course and prognosis of CHD. Improvement of quality of life (QoL) is now a major goal of CHD treatment.Objective To assess the QoL in children after cardiac surgery for CHD.Methods A cross-sectional study was performed in children aged 2 to 18 years. The case group had 20 children with a history of corrective heart surgery in the 12 months prior to the study. The control group had 20 healthy children, age-matched  to the case group. The QoL of both groups was assessed by Pediatric Quality of Life Inventory (PedsQL) Generic Core Scales. The same post-operative children were also assessed with the PedsQL Cardiac Module. Data were analyzed using T-test with P < 0.05 as the level of significance.Results This study recruited 40 subjects: 20 post-operative and 20 healthy children. PedsQL Generic Core Scales assessment showed significant differences between groups in the physical function parameter of QoL (P<0.05) in children aged 13-18 years, but there were no significant differences in the social, emotional, and school function parameters. In children aged 2-12 years, there were no significant differences in physical, social, emotional, or school parameters. The PedsQL Cardiac Module assessment revealed that 35% of post-operative children was at risk for physical appearance problems, 80% was at risk for anxiety problems, 40% was at risk for cognitive problems, and 80% was at risk for communication problems.Conclusion Thirteen to 18-year-old children with non complex CHD have poorer physical function than healthy children. Post operative children are at risk for physical appearance, anxiety, cognitive, and communication problems.
