Heart failure & cardiomyopathies
Mortality in Recipients of Durable Left Ventricular Assist Devices Undergoing Ventricular Tachycardia Ablation
Authors' conclusion
VT occurrence within 1 year of LVAD implantation was associated with worse survival. However, performance of VT ablation in this population was correlated with improved survival compared with medical management alone.
Study context
- Population
- Durable Left Ventricular Assist Device (LVAD) recipients, Baylor St. Luke's Medical Center and Texas Heart Institute, January 2011–January 202153% with post-implant ventricular tachycardia (VT)
- Participants
- 575 recipients
- Exposure
- VT ablation vs medical therapy alone in LVAD recipients with post-implant VT
- Outcome
- All-cause mortality
