Abstract
Provided herein is a prosthetic device in patients with ventricular assist device (VAD) support and a closed off aortic valve orifice, which reestablishes the formation of normal fluid flow patterns in the aortic root. The prosthesis includes a circular body having a first surface and a second surface and a projection disposed on the first surface of the body, wherein the projection includes a plurality of walls extending away from the first surface of the body, each wall being positioned such that a first side edge contacts a center of the body, thereby forming a plurality of intercepted arcs, each located between adjacent walls; and a plurality of concave parabolic surfaces, each disposed within an intercepted arc. Also provided are methods of using the prosthetic device to reduce thrombosis formation in patients with VAD support.
