ABSTRACT:
A prosthetic heart valve (valve) composed of a base ring adapted to house a suture ring in its exterior and two leaflets arranged to assume an open position and a closed position in order to regulate the blood flow in one direction, wherein the base ring is provided with two recesses with curved surfaces situated in diametrically opposite positions. Each of the recesses communicate with the exterior through a chimney-like aperture formed in the body of the base ring in correspondence with the recess. Each of the curved recesses has a substantially flat surface bounding its upper part and two spherical bottom surfaces in its lower part, separated by a separator body essentially in the shape of a semi-spherical-nail.
