Sixty-four patients with pure mitral insufficiency were operated upon. Thirty of them had torn chordae tendineae. It was possible to repair the mitral valve in 57 patients and there were five operative deaths. One patient had a femoral artery embolus and another had a cerebral embolus. The incidence of peripheral embolization was 4 per cent compared with 40 per cent reported for ball valve replacement.Forty-eight of the 57 patients with repair (84 per cent) were living and well with at most a grade II/VI apical systolic murmur up to seven and a half years after operation. There has been no evidence of recurrence in these patients.In approximately 90 per cent of patients with pure mitral insufficiency, repair should be performed. When feasible, repair is more satisfactory than valvular replacement, with not only excellent long-term results, but far less morbidity than is reported with ball valve replacement.

A disc valve of new design was used successfully for the replacement of the mitral valve in patients with rheumatic mitral valve disease. This valve would appear to have the following advantages over the mitral ball valve prosthesis:* Lower left atrial pressure after replacement.* Elimination of the hazard of left ventricular outflow tract obstruction with mitral valve replacement.* Decreased incidence of thromboembolization.* Abolition of possibility of ventricular septal irritation. Despite the better outlook for this valve compared with the ball valve for mitral valve substitution, the mitral valve should always be repaired whenever feasible. Repair is possible in the majority of patients.
