Abstract

Ventricular assist devices (VADs) have become an important therapy for advanced heart failure, however, the prognosis of those who receive a biventricular assist device (BiVAD) is still poor. We enrolled 70 patients who underwent paracorporeal VAD (Nipro-VAD®) implantation between 2004 and 2015 and studied the preoperative risk factors, including hemodynamic parameters for RVAD requirement. Furthermore, 2-year survival was compared between the BiVAD group and LVAD only group. Fourteen patients (20%) required RVAD. The BiVAD group had a significantly smaller left ventricular diastolic/systolic dimension, lower mean pulmonary artery wedge pressure (PAWP), lower cardiac index (CI), higher pulmonary vascular resistance (PVR), higher mean right atrial pressure (RAP), lower pulmonary artery pulsatility index (PAPi), lower right ventricular stroke work index (RVSWI), and higher mean RAP/mean PAWP ratio preoperatively. After multivariate analysis, only PVR > 4.5 Wood units: WU (P = 0.013, odds ratio: OR 7.9) and mean RAP/mean PAWP > 0.8 (P < 0.001, OR 14.4) were significant predictors for RVAD requirement. From these odds ratios, we assigned 1 point to PVR > 4.5 WU and 2 points to mean RAP/mean PAWP > 0.8. This simple scoring method ad...Continue Reading
