Cryoablation for Ventricular Tachycardia Originating from Anterior Papillary Muscle of Left Ventricle Guided by Intracardiac Echocardiography

<div>(a) Intracardiac electrogram showing bipolar prepotential preceding the surface QRS by 35 milliseconds (arrow) and unipolar QS pattern (asterisk) recorded at the ablation site during ventricular tachycardia. (b) Programmed stimulation during cryoenergy application did not induce ventricular arrhythmia. The noise in the ablation channel (ABL) is due to ice artifact.</div>
