Abstract
BackgroundAortic valve insufficiency can have significant hemodynamic consequences for patients with left ventricular assist devices. A circulation loop can limit systemic blood flow and increase left ventricular filling pressure.Case presentationA 64-year-old male with non-ischemic dilated cardiomyopathy underwent Heartware™ HVAD left ventricular assist device implantation with successful concomitant aortic valve replacement with an Edwards Intuity rapid deployment prosthetic valve.ConclusionsThe use of this rapid deployment valve may have benefits over other techniques including shorter cross clamp times during surgery, intermediate-long term durability, and preservation of aortic valve opening to allow for potential ventricular recovery. The Intuity rapid deployment valve should thus be considered a viable and suitable option for aortic insufficiency intervention during LVAD implantation.

Aortic valve insufficiency can have significant hemodynamic consequences for patients with left ventricular assist devices
The regurgitation can create a circulation loop limited to the left ventricle (LV), left ventricular assist devices (LVAD), and ascending aorta, leading to decreased systemic blood flow and increased LV filling pressure [1, 2]
Greater than mild Aortic valve insufficiency (AI) is generally considered an indication for intervention on the aortic valve (AV) at the time of LVAD implantation [3]
Summary
The use of this rapid deployment valve may have benefits over other techniques including shorter cross clamp times during surgery, intermediate-long term durability, and preservation of aortic valve opening to allow for potential ventricular recovery. The Intuity rapid deployment valve should be considered a viable and suitable option for aortic insufficiency intervention during LVAD implantation.
