Mitral ring annuloplasty by biological material.

Mitral annuloplasty is an integral part of mitral valve repair. Several types of techniques have been described for mitral annuloplasty. The autologous pericardium is used for mitral annuloplasty to allow mitral annular flexibility. Complete mitral ring annuloplasty is done using a D-shaped bovine pericardium. Classical annuloplasty sizers are utilized for the sizing and shaping of bovine pericardium. Biological material covers all parts of the mitral annulus and allows annular flexibility.
