Aortic valve repair using geometric ring annuloplasty

In the 1980s, Carpentier and Cosgrove, reported the first series of aortic valve repair using Cabrol commissural annulopastia for annular reduction and leaflet wedge resection for prolapse correction. Later T. David and J. Schaefers describes valve-sparing techniques in aortic root surgery for aneurysms. The advantages of valve repair are multiple and also affect survival compared to prostheses. Studies with CT scan of the aortic root and in patients undergoing successful bicuspid valve repair using sub-commissural annuloplasty and Schaefers' leaflet reconstruction, shown an elliptical configuration of the aortic ring. This has led to the development of a rigid internal ring for the aortic valve with the knowledge obtained with the principles of mitral valve repair. This manuscript describes the bases of the development, principles, implantation technique and current experience of the so-called "internal remodeling rings" for aortic valve repair.
