Abstract
A prosthetic heart valve has three cusp regions positioned at an inflow end intermediate three commissure regions positioned at an outflow end thereof. A support frame including three cusp positioners is fixed with respect to a leaflet frame and located intermediate each pair of adjacent commissure regions. The valve is desirably compressible. In the aortic valve position, the cusp positioners angle outward into contact with the sinus cavities, and compress the native leaflets if they are not excised, or the aortic wall if they are.
