Open-chest epicardial ablation of ventricular tachycardia during a left ventricular assist device implantation: a case report.

ABSTRACT:

Background

Ventricular arrhythmias (VAs) are common after a left ventricular assist device (LVAD) implantation. Further, the majority of post-LVAD ventricular tachycardias (VTs) are secondary to a preexisting cardiomyopathy substrate. Intraoperative ablation of patients with recurrent preoperative VTs may reduce post-LVAD VTs.

Case summary

A 59-year-old female with advanced heart failure due to non-ischaemic cardiomyopathy (LV ejection fraction = 24%) and recurrent VTs was referred for an LVAD implantation as a bridge to a heart transplant (INTERMACS Profile-5A). 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 arrhythmogeni
