The aortic root has long been considered an inert unidirectional conduit between the left
ventricle and the ascending aorta. In the classical definition, the aortic valve leaflets (similar …

Background Idiopathic ventricular arrhythmias (VAs) can be rarely ablated from the
noncoronary cusp (NCC) of the aorta. Objective The purpose of this study was to investigate …

The traditional route for teaching cardiac anatomy involves didactic instruction, cadaver
dissections, and familiarization with the main structure and relationships of the cardiac …

Introduction: Localization of premature ventricular contraction (PVC) origin to guide the
radiofrequency ablation (RFA) procedure is one of the prominent clinical goals of non …

792 TADA H input to the AV node, however, is located directly posterior to this commissure
and is thus related to the anterior portion of the NSV. The triangle between the right-and non …

Recent findings have shed new light on the basic and clinical electrophysiology of the
outflow tract, which may enhance the management of patients with benign outflow tract …

Background The electrophysiological characteristics of idiopathic ventricular arrhythmias
(VAs) from the noncoronary sinus (NCS) have not been fully described. Objectives This …

Non-coronary cusp (NCC) is a rare site for ventricular arrhythmias because it does not come
into direct contact with the ventricular myocardium. Instead, the NCC comes in contact with …

Background Idiopathic ventricular tachycardia (VT) and/or premature ventricular contractions
(PVCs) arise most commonly from the right ventricular outflow tract and less frequently from …

The underlying mechanism of tachyarrhythmias in patients late after repair of tetralogy of
Fallot (TOF) is most commonly macroreentry around scars and prosthetic materials used for …
