RESUMO
Congenital diverticulum is an uncommonly detected cardiac lesion, especially in infancy. However, its association with cyanotic congenital heart disease is extremely rare. In the current work, we report a case diagnosed in the neonatal period with tetralogy of Fallot and pulmonary valve atresia associated with a large congenital diverticulum originating from the right ventricle.

Ventricular diverticula are saccule-like structures formed by the protrusion of the ventricular myocardium from the endocardial surface towards the free wall. Most diverticula are muscular structures, and patients usually have no obvious clinical symptoms. However, diverticula may contribute to arrhythmogenesis due to localized myocardial structural disturbances. Right ventricular apical diverticulum (RVAD) is very rare, and we report a case of highly symptomatic accelerated idioventricular rhythm (AIVR) originating from the RVAD that underwent intracardiac echocardiography (ICE)-guided catheter ablation with no recurrence during follow-up.
