Improvement in 2-year survival for ventricular assist device patients after implementation of an intensive surveillance protocol

Survival improved for DT and BTT VAD patients after implementation of the ISP, with a dramatic decrease in hazard for death. Although the transition from pulsatile to axial flow technology occurred during the study period and likely contributed to improved outcomes, the institution of the ISP provided an important and significant contribution to improved survival through a proactive approach to patient management, allowing earlier identification of potential adverse events. For optimal outcomes, VAD patients require intensive follow-up surveillance protocols that have previously become standard in the care of heart transplant patients.
