Cardiac sympathetic denervation for catecholaminergic polymorphic ventricular tachycardia

Abstract

Catecholaminergic polymorphic ventricular tachycardia (CPVT), a rare inheritable fatal arrhythmogenic disorder, is difficult to diagnose and is a challenge to manage. A 21-years-old man presented with recurrent exertional syncope and complex multifocal ventricular ectopy. CPVT was diagnosed based on the clinical criteria, despite the absence of some classical findings. The patient underwent cardiac sympathetic denervation (CSD) after lifestyle modification and pharmacological management were ineffective. CSD proved to be effective. The patient did not have any exertional symptoms or recurrence of syncope at follow-up period of 1 year. The present case report adds to the growing evidence in favour of CSD for CPVT.
