Novel Techniques in Mitral Repair Extended and Rotational Chordal Transfer

Abstract

Mitral valve repair is preferable to mitral valve replacement because of low rate of thromboembolism, resistance to endocarditis, excellent late durability, and no need for anticoagulation in the majority of patients. This article describes 2 novel techniques for repairing the anterior mitral leaflet prolapse. The extended chordal transfer is achieved by transferring an extended segment of posterior mitral leaflet and, rotational chordal transfer, by rotating the transferred segment either vertical or horizontal. Both techniques are simple and reproducible. It uses patient's own natural chorda and eliminates the problem of knotting and determination of appropriate chordal length faced with other techniques.
