Changing Strategy Between Bridge to Transplant and Destination LVAD Therapy After The First 3 Months: Analysis of the STS- INTERMACS Database.
Changing Strategy Between Bridge to Transplant and Destination LVAD Therapy After The First 3 Months: Analysis of the STS- INTERMACS Database. Journal of cardiac failure Rali, A. S., Inampudi, C., Zalawadiya, S., Shah, A., Teuteberg, J. J., Stewart, G. C., Cantor, R. S., Deng, L., Jacobs, J. P., Kirklin, J. K., Stevenson, L. W. 2023Abstract
Left ventricular assist devices (LVADs) have been implanted as bridge to transplantation (BTT), bridge to candidacy (BTC) or destination therapy (DT) based on relative and absolute contraindications to transplantation. Multiple factors may lead to change in the strategy of support after LVAD implantation.From INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) 2012-2020, 11,262 patients survived to 3 months on continuous flow LVADs with intent of BTT or DT. Pre-implant characteristics and early events post-LVAD were analyzed in relation to changes in BTT or DT strategy during the next 12 months.Among 3216 BTT patients at 3 months, later transplant de-listing or death without transplant occurred in 536 (16.7%) and, was more common with age, Profiles 1-2, renal dysfunction, and independently for prior cardiac surgery (HR 1.25, 95% CI 1.04-1.51, p?=?0.02). Post-LVAD events of infections, gastrointestinal bleeding, stroke, and right heart failure defined by inotropic therapy predicted de-listing and death, as did in-hospital location at 3 months (HR 1.67, 95% CI 1.20-2.33, p =0.0024). Of 8046 patients surviving to 3 months with intent as destination therapy, 750 (9.3%) subsequently underwent listing or transplant, often with initial history of acute HF (HR 1.70, 95% CI 1.27-2.27, p?=?0.0012) or malnutrition-cachexia (1.73, 95% CI 1.14-2.63, p?=?0.0099). Multiple gastrointestinal bleeding events (=4) with LVAD increased transition from BTT to DT (HR 4.22, 95% CI 1.46-12.275, p?=?0.0078) but also from DT to BTT (HR 5.17, 95% CI 1.92-13.9, p?=?0.0011).Implant strategies change over time in relation to pre-implant characteristics and adverse events post implant. Pre-implant recognition of factors predicting later change in implant strategy will refine initial triage, while further reduction of post-LVAD complications will expand options including eventual consideration of heart transplant.
