Abstract

Congenitally corrected transposition of the great arteries (CCTGA) is a rare congenital heart disease which may present sudden cardiac death presumably due to malignant ventricular tachycardia (VT). In patients with congenital heart disease, knowledge of arrhythmogenic substrate is crucial for planning an ablation procedure. We present the first description of the arrhythmogenic endocardial substrate of a non-iatrogenic scar-related VT in a patient with CCTGA.

Keywords: congenitally corrected transposition of great arteries; endocardial substrate; ventricular tachycardia.
