Background: The HeartMate 3 (HM3) has become among the most widely utilized durable left ventricular (LV) assist devices (LVAD) owing to reduced rates of pump thrombosis, bleeding, and stroke. One limitation of the HM3 is its large size, which poses a challenge for implantation in smaller LVs. Herein, we describe a novel technique for durable LVAD implantation in patients with a small LV. Methods: Patients who underwent durable LVAD implantation from January 2020 to August 2024 were included in this study. The modified technique involved excision of the mitral valve (MV) and associated apparatus to create room for the LVAD inflow. The primary outcome was mortality, and secondary outcomes included rates of postoperative complications and hemodynamic parameters. Patient follow-up was until September 2024. Results: Eleven patients were included in this study. All patients received an HM3. The median preoperative LV end-diastolic diameter was 5.1 cm. The median total time on LVAD was 149 days, and overall mortality was 27.2% occurring a median of 204 days post-LVAD implantation. Four patients (36.4%) underwent heart transplantation and 4 (36.4%) were alive on LVAD at last follow-up. Proportions of morbidity included readmission for heart failure (n = 2, 18.2%), cerebrovascular accident (n = 2, 18.2%), and pump thrombosis (n = 0). Conclusions: The small LV has been a significant challenge for durable LVAD insertion and is often considered a contraindication. A modified approach to LVAD insertion, including excision of the MV and associated apparatus and alignment of the LVAD inflow cannula with the MV orifice, allows for LVAD implantation in patients with a small LV. © 2025 International Society for Heart and Lung Transplantation
