Serial changes in @entity339 after anterior mitral valve repair were examined by transesophageal echocardiography (TEE) in 34 of 86 consecutive @entity1 with pure @entity339 who underwent anterior mitral valve repair from 1987 to 1996. The @entity1 were divided into two groups: 15 @entity1 undergoing mitral repair with @entity736 ( @entity736 ; @entity736 group) and 19 undergoing conventional mitral repair without @entity736 (non- @entity736 group). The @entity736 group included 11 @entity1 and 4 @entity1 with a mean age of 52.1 years. They were followed for mean 22.8 +/- 12.0 months. The non- @entity736 group included 12 @entity1 and 7 @entity1 with a mean age of 53.9 years. They were followed for mean 33.9 +/- 20.4 months. @entity339 jet areas were observed at the time of operation, 1 month after mitral valve repair, and in the late follow-up period. Regurgitation jet areas were 0.7 +/- 0.7, 1.1 +/- 0.9 and 2.5 +/- 2.1 cm2 in the @entity736 group, and 1.1 +/- 1.3, 2.4 +/- 1.7, 4.7 +/- 2.9 cm2 in the non- @entity736 group. The jet area was significantly smaller in the @entity736 group than in the non- @entity736 group at 1 month after operation and in the late follow-up period. Moderate to severe regurgitation was observed in two @entity1 (13.3%) in the @entity736 group, and eight @entity1 (42.1%) in the non- @entity736 group. Mitral valve repair with @entity736 showed better results than conventional mitral valve repair without @entity736 during the mean follow-up period of 23 months.
