摘要：
A system for replacing a deficient native aortic valve includes an implantable prosthetic valve having a self-expandable frame and a valve assembly formed with three valve leaflets. The self-expandable frame includes three angularly spaced longitudinal bars of fixed length defining respective slots and a plurality of web-like constructions extending between and connected to the longitudinal bars. The valve assembly includes commissures extending outwardly through the slots where they are supported on the outside of the frame. Each leaflet includes an inlet end portion secured to the inside of the frame with stitching extending through the leaflet and around adjacent frame portions. The system also includes a restriction tube adapted for insertion into a patient's body. The prosthetic valve is capable of being crimped for insertion into the restriction tube and capable of self-expansion upon release from the restriction tube for deployment in the deficient native aortic valve.
