Abstract Background Despite technological advancements, pump durability and pump‐related complications continue to affect and adversely impact the lives of patients with end‐stage heart failure on left ventricular assist device (LVAD) support. In an attempt to avoid recurrent LVAD‐related complications, there may be circumstances where it is clinically advantageous to exchange a patient's device from HeartMate II to HeartWare HVAD. However, there is a paucity of data that describes the safety and feasibility of such an approach. Objective We present the largest single‐center series of HeartMate II (HMII) to HeartWare (HVAD) device exchanges. Methods A retrospective review of 11 patients who underwent HMII to HVAD exchange from 2012 to 2017 was conducted to evaluate patient characteristics, incidence of postoperative complications, and survival. Results Eleven male patients (mean age 55 ± 14.4 years) underwent HMII to HVAD device exchange. One patient expired on postoperative day 7 secondary to sepsis. One patient was lost‐to‐follow‐up after 23 months. An additional three patients died at 5, 7, and 24 months. Mean follow‐up after device exchange was 1555 ± 311 days for the remaining six patients. None of the 11 study patients underwent LVAD explant, further device exchange, or heart transplant. Conclusion Exchange of an HMII LVAD to an HVAD can be performed safely with acceptable perioperative morbidity and mortality.
