Abstract: The present invention provides a system and method for retaining, positioning and releasing a prosthetic heart valve. The system includes a valve holder, and a control handle. The valve holder includes a connection base and at least one holding arm. The holding arms are distributed around a periphery of the connection base, with the holding arms having positioning structures at the distal side thereof for engaging with an outflow side of the prosthetic heart valve. The control handle is coupled to the valve holder for controlling the valve holder.

Abstract: A surgical prosthetic heart valve has a supporting structure and a plurality of leaflets, the supporting structure generally having an annular shape with a blood flow channel defined in the annular shape and having opposite inflow and outflow sides along an axial direction of the annular shape, the plurality of leaflets connected to the supporting structure to control the blood flow channel to open or close. The supporting structure includes a first annular band and a second annular band, both of which are provided with deformable sections spaced from each other in the circumferential direction for allowing diameter expansion of the respective annular bands. The surgical heart valve achieves the diameter expansion of the annular bands through the deformable sections, thereby addressing the problem of postoperative variation in a valve-in-valve operations.
