Submitral diverticulum in hypertrophic cardiomyopathy can be detected by CT angiography and may serve as a phenotypic marker for electrophysiological consequences, assisting in ablation planning.

No clinical data extractable; leaves open any role for submitral diverticulum in hypertrophic cardiomyopathy ablation planning.
Submitral diverticulum of left ventricle is rare entity often presumed to be congenital in origin having preserved myocardial contractility and function. Patients may be entirely asymptomatic for many years or may have varied clinical or electrophysiological manifestations. We present a case of a middle-aged man with hypertrophic cardiomyopathy who presented with atrial fibrillation and ventricular tachycardia detected to have submitral diverticulum on computed tomography angiography which further assisted in planning of electrophysiology ablation.
