BackgroundVentricular tachycardia (VT) can persist following placement of a left ventricular assist device (LVAD). The optimal management strategy for VT during the peri-LVAD period is unknown.Case PresentationsTwo case reports are presented that describe epicardial and endocardial VT ablation performed during LVAD placement. Subsequently, both patients developed LVAD thrombosis, a known and dreaded complication of LVADs, requiring re-operation.ConclusionsWhile LVAD thrombosis is likely multifactorial and remains an area of active research, these two cases should increase awareness of the possible risks of VT ablation-especially endocardial ablation-during LVAD placement. Further research is needed to understand the effects of VT ablation during the peri-LVAD period.
