Left ventricular assist device (LVAD) implantation increases survival and quality of life for patients with advanced heart failure.¹ Because of device design, competence of the native aortic valve is critically important. Even trivial aortic insufficiency could worsen with time,² and the regurgitant flow could make the device ineffective for hemodynamic support.

Managing native aortic valve insufficiency at the time of LVAD implantation has been challenging. Various procedures to prevent aortic insufficiency have been anecdotally reported (eg, aortic valve replacement with a bioprosthetic valve or with a polytetrafluoroethylene patch, or primary closure of the aortic valve opening).^3-5 Such procedures have been performed successfully, but they could make surgery more complicated. We describe a simple coaptation stitch method of dealing with central aortic insufficiency at the time of LVAD implantation in 2 patients.
