Abstract
- Purpose Outcomes of patients with small body size following HM3 LVAD implantation have not been well characterized. We sought to compare preoperative characteristics and clinical outcomes among patients stratified by body surface area. Methods Patients who received a HeartMate 3 LVAD at our institution between October 1, 2015 and June 30, 2019 were analyzed. Patients who received a HM3 LVAD as pump exchange were excluded. The cohort was divided in 4 groups: BSA ≤1.8 m2 (group 1), BSA >1.8 - ≤2.0 m2 (group 2), BSA >2.0 - ≤2.2 m2 (group 3) and BSA >2.2 (group 4). Results One hundred and nineteen patients were included in this analysis. Preoperative characteristics and postoperative results of each group are shown in Table 1. Group 1 patients were older and mostly females. A history of diabetes was less common in this group. Mean postoperative length of stay was similar between groups. Pump speed at the time of discharge was lower in group 1 patients. Mean follow-up was similar between groups. Mean days out of the hospital after discharge did not differ among the groups. One-year survival was 93% for group 1, 85% for group 2, 86% for group 3 and 84% for group 4 (p=0.69). Kaplan Meier survival curves are shown in Figure 1 (log rank: 0.692). Conclusion Outcomes following HM3 LVAD implantation were comparable between patients with small body surface area and patients with larger body size. Small body size should not be an exclusion criteria for HM3 LVAD implantation in patients with advanced heart failure who are otherwise candidates for durable mechanical support.
