Utility of distinctive local electrogram pattern and aortographic anatomical position in catheter manipulation at coronary cusps.

Abstract

BACKGROUND The coronary cusps have recently become target sites for radiofrequency catheter ablation of both outflow tract ventricular arrhythmias originating near the coronary cusps (CC-VA) and atrial tachyarrhythmias such as focal atrial tachycardia originating near the noncoronary cusp (NCC-AT). However, the relation between local electrograms recorded… (More)
