During the past 5 years, 45 @entity1 were operated on for @entity339 due to @entity453 . Preoperatively, 33 had @entity951 ; 24 were in NYHA Class IV; and 21 were in Class III. The ejection fraction ranged from 0.1 to 0.7 (mean 0.40). The degree of @entity339 ranged from Grade II/VI to Grade V/VI. Mitral repair was performed in 38 (84%) and replacement in seven (16%). At surgery, a @entity1377 muscle or torn chordae tendineae with a dilated annulus were found in 21 @entity1 and a dilated annulus only in 24. Seventy-six vein grafts and eight internal mammary anastomoses were performed. There were three hospital deaths (7%). Postoperative follow-up of 36 long-term survivors revealed symptomatic improvement in all but one @entity1 . Twenty @entity1 were in NYHA Class I, 15 in Class II, and one in Class III. In eight @entity1 restudied, 17 of 18 vein grafts were patent (94%). @entity339 decreased from a mean of 2.7 to a mean of 0.6 (P less than 0.001). Average improvement in ejection fraction was 0.14, significant at P less than 0.01. Actuarial studies revealed an 80% survival rate at 5 years.
