Mitral annuloplasty: different surgical techniques.

Mitral annuloplasty has always been a target for the cardiac surgeon, even before the era of open heart surgery. We describe here commisural annuloplasty, annular reduction with rings, and supported annular reduction without rings, which are, at the present time, the three types of annuloplasties employed. The increasing incidence of mitral valve surgery for degenerative disease suggests reconstructive surgery with autologous patients tissue as the gold standard.
