Abstract :
A 59-year-old woman was referred to the institution with burdens of idiopathic ventricular tachycardia (IVT). Electroanatomic
mapping revealed a complex fractionated, high frequency potential with long duration preceding the QRS onset of the IVT. The
real end point of ablation was the disappearance of the conduction block of Purkinje potential during the sinus rhythm besides
the disappearance of the inducible tachycardia. Location of distal catheter was at the moderator band (MB) by transthoracic
echocardiography (TTE). Only irrigated radiofrequency current was delivered at both insertions of the MB which can completely
eliminate the IVT.
