Abstract

BACKGROUND: Severe right ventricular failure necessitating a right ventricular assist device (RVAD) complicates 6% to 11% of left ventricular assist device (LVAD) implants. Patient outcomes for those receiving durable continuous-flow VADs in a biventricular configuration (i.e., BiVAD) have been reported in limited case series. METHODS: Data from United States centers with ≥ 6 BiVAD implants were collected. Characteristics and outcomes of patients receiving contemporaneous (i.e., same surgery) vs staged implantation of the HVAD as a BiVAD were compared. RESULTS: From 2011 to 2017, 46 patients received durable BiVADs and had the following characteristics: median age, 46 years (interquartile range [IQR], 19–67 years), non-ischemic cardiomyopathy (80%), bridge to transplant (83%), Interagency Registry for Mechanically Assisted Circulatory Support Profile 1 or 2 (92%), use of temporary circulatory support (37%), right atrial pressure 19 mm Hg (IQR, 14–23 mm Hg), and cardiac index of 1.6 liters/min/m2 (IQR, 1.2–2.1 liters/min/m2). Operative mortality was 33%. Equal numbers of patients received a right atrial or right ventricular implant. Contemporaneous BiVAD implantation occurred in 31 patients (67%), and compared with 15 patients (33%) with staged implants, these patients had a shorter intensive care unit length of stay of 12 days (IQR, 7–23 days) vs 42 days (IQR, 28–48 days, p = 0.035) and were more likely to be discharged from the hospital on BiVAD support (61% vs 27%, p = 0.04). RVAD thrombosis developed in 17 patients (37%). Patients with contemporaneous BiVAD implants had a 1-year survival of 74% compared with 40% in staged BiVAD patients (p = 0.11). CONCLUSIONS: Patients receiving durable BiVADs represent a critically ill patient population with severe biventricular failure who have high operative mortality and RVAD thrombosis rates. The 1-year survival for patients receiving contemporaneous BiVADs in experienced centers mirrors other contemporary durable biventricular support strategies.
