Abstract

A 68-year-old woman with idiopathic dilated cardiomyopathy suffered from drug-resistant monomorphic ventricular tachycardia (VT). Electrophysiological study revealed a re-entrant VT circuit located just beneath the inferior mitral valve annulus. The VT was considered to be related to the mitral valve isthmus and was abolished by radiofrequency ablation. The patient died 2 years after the ablation due to worsening of heart failure and an autopsy was performed. Pathological examination revealed ablation scar tissue on the localized myocardial bundle running parallel to the mitral valve annulus. Therefore, this bundle appeared to comprise the slow conduction area of the re-entrant VT in this case.
