Highlights that epicardial myocardium can be a critical component for VT substrate in ischemic cardiomyopathy, demonstrating a three-dimensional reentry circuit.
In ischemic cardiomyopathy, endocardial reentry has traditionally been the mechanistic paradigm for understanding ventricular tachycardia (VT). However, recognition is growing that epicardial myocardium is a critical component for VT substrate, even in patients with ischemic cardiomyopathy. In this report, we present a novel case of a three-dimensional VT reentry involving epicardial components and an endocardial exit.
Kotake et al. (Thu,) conducted a case report in Ischemic cardiomyopathy with ventricular tachycardia (n=1). Epicardial ablation vs. Endocardial ablation was evaluated on Ventricular tachycardia recurrence. Epicardial ablation successfully terminated recurrent ventricular tachycardia and prevented recurrence for at least two years in a patient with ischemic cardiomyopathy.
