Reasons for failure of previous catheter ablation attempts, site of origin of ventricular
arrhythmias, and alternative interventional approaches used. *One patient in this group had 1
previous attempt at epicardial mapping, after which adhesions developed and repeat epicardial
access could not be obtained. †Epicardial fat prohibiting ablation in right ventricular (RV) free
wall in 2 patients and inferior left ventricular (LV) in 1 patient.

Surgical cryoablation targets. *One patient had 3 sites targeted in the same procedureinferobasal free wall right ventricle (RV), septal right ventricle right ventricular outflow tract
(RVOT), inferobasal septal left ventricle (LV).
