ABSTRACT
Cardiac surgeons have hesitated to perform valvuloplasty for MR caused by elongated or ruptured chordae of the anterior leaflet (AL) of the mitral valve. We experienced three cases of successful chordal reconstruction (CR) to the AL last year. Two of them were due to elongation of all chordae tendineae to the AL. Four CRs, one chordal shortening, cleft closure and ring annuloplasty (AP) were performed in one case, and 8 CRs to the AL, two to the posterior leaflet, commissural closure and ring AP in another. In the third case 2 CRs combined with Reed's AP, closure of ASD and tricuspid AP were performed. The MR disappeared in one case and improved to grade I in others postoperatively. NYHA classes improved from class III or IV to I or II postoperatively. The MRs have not increased 6 to 12 months after the surgery. The CR with PTFE suture enabled to do the valvuloplasty for the chordal abnormalities of the AL without valve resection. This technique seems to be adequate for repairing a major prolapse of the AL caused by multiple chordal abnormalities.
