Association of Aortic Root and Valve Morphology With De Novo Aortic Valve Regurgitation After Implantation of Left Ventricular Assist Device.

ABSTRACT:

Background

The development of aortic valve regurgitation (AR) negatively affects the survival of patients with continuous-flow left ventricular assist device (LVAD) support. Although several risk factors have been identified, little is known about the effect of preoperative aortic root and valve morphology on the development of de novo AR after LVAD implantation.

Methods

Between April 2018 and September 2023, 87 patients underwent durable LVAD implantation at our department. Of these, the 15 eligible patients who underwent preoperative electrocardiography-synchronized cardiac contrast-enhanced computed tomography were included in this study. Baseline aortic root and valve morphology and its relationship with the postoperative development of AR were retrospectively reviewed.<
