XXXX due to @entity397 . Early and late results of valve repair.

@entity1 @entity1031 @entity397 @entity339
From 1958 through 1980, 131 @entity1 had repair of @entity397 of the mitral valve; 62% were @entity1 . Ages ranged from 5 to 70 years (median 57). Chordae to the anterior mitral leaflet were @entity397 in 44 @entity1 (34%), to the posterior mitral leaflet in 85 (65%), and to both leaflets in two @entity1 (1%). The mitral valve was repaired by leaflet plication without resection in 116 @entity1 , plication after wedge resection of the unsupported leaflet in six, Ivalon sponge buttress of the posterior leaflet in three, resuspension of chordae in two, and annuloplasty alone in the remaining four. Mitral valve annuloplasty was performed in addition to leaflet repair in 115 @entity1 (88%). Operative (less than 30 days) mortality was 6.1%. Survival rate of @entity1 dismissed from the hospital was 92% at 5 years and 73% at 10 years. There were no differences in late survival or risk of reoperation for recurrent or residual @entity339 between @entity1 with @entity397 chordae to the anterior leaflet and those with @entity397 chordae to the posterior leaflet. Survival was significantly better for the group with repair than it was for a group that underwent mitral valve replacement for @entity397 chordae during this same time interval (5 year survival rate, 92% versus 72%, p less than 0.003). The incidence of @entity1031 after repair was 1.8 episodes/100 @entity1 -years compared with 8.0 episodes/100 @entity1 -years after replacement. Our data indicate that valvuloplasty is the procedure of choice for most @entity1 with @entity339 owing to @entity397 , including selected @entity1 with @entity397 chordae to the anterior leaflet.
