Abstract:
A prosthetic heart valve comprising:a support formed with a base ring defining a ring plane, of noncircular shape, and having a relatively long major axis and a relatively short minor axis perpendicular to the major axis and defined by short and long minor subaxes meeting at the major axis; a pair of arcuate walls projecting transversely of the plane from the base ring generally to respective sides of the major axis, meeting at points directed away from the base ring, and having arcuate edges extending between the points, one of the walls forming a larger arc than the other of the walls, the walls being shaped such that a point plane including a line connecting the points and the major axis forms with a plane including the major axis and perpendicular to the ring plane an angle of between 10Â° and 20Â°; and respective flexible valve cusps attached to the edges, the valve cusp attached to the edge of the smaller-arc wall being of smaller surface area than and inclined at a more obtuse angle to the ring plane than the valve cusp attached to the edge of the larger-arc wall.
