Further, the majority of post-LVAD ventricular tachycardias (VTs) are secondary to a preexisting cardiomyopathy substrate.

The previous endocardial ablation failed due to an epicardial arrhythmogenic substrate. Therefore, open-chest epicardial mapping during the LVAD implantation was indicated and three target areas of the arrhythmogenic substrate were found, which were ablated by radiofrequency applications. To minimize the cardiopulmonary bypass time, cardiopulmonary bypass was initiated after ablation, and then, an LVAD was implanted. An additional 68\u2005min was required for mapping and ablation. All procedures were performed without any complications, and the post-operative course was uneventful. Thereafter, no VT episodes were observed without any anti-arrhythmic drugs during a 15-month follow-up with LVAD support.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
