Abstract
A prosthetic heart valve assembly includes a self-expandable stent having an inlet end and an outlet end and a passageway extending therethrough. The stent includes a plurality of rows of prongs on the outer surface of the stent. A valve portion comprising a plurality of leaflets is positioned within the passageway for permitting blood to flow through the passageway from the inlet end to the outlet end while blocking flow in the opposite direction. The stent further includes a flared upper portion shaped for placement along a supra-annular surface of an annulus for preventing downward migration of the prosthetic valve assembly into a ventricle. Each of the prongs has a tip pointing toward the inlet end for penetrating surrounding tissue and preventing upward migration of the prosthetic heart valve assembly toward an atrium.
