BACKGROUND: This study was a long-term Doppler echocardiographic assessment of mitral valve repair for anterior @entity3454 using expanded @entity736 sutures. METHODS: Between April 1992 and December 2003, we performed mitral valve repair using expanded @entity736 sutures in 204 @entity1 (mean age, 54.6 years) with severe @entity339 ( @entity339 ) having anterior @entity3454 . The cause of @entity340 was degenerative in 181 @entity1 (88.7%). Postoperative serial transthoracic echocardiographic studies were performed in all hospital survivors. Residual @entity339 flow detected by color Doppler echocardiography was classified according to the maximum regurgitant jet area. RESULTS: The 30-day mortality of 204 @entity1 was 1.4% (3 deaths). There were 12 late deaths and 14 reoperations in this series. Kaplan-Meier survival and freedom from reoperation at 12 years were 84.6% +/- 4.0% and 89.9% +/- 2.9%, respectively. Postoperative transthoracic echocardiographic assessment after discharge (mean follow-up, 4.2 +/- 3.0 years) showed less than mild regurgitation (maximum regurgitant jet area < 4.0 cm2) in 80.9% of the @entity1 . Overall, freedom from severe @entity339 (maximum regurgitant jet area > or = 7.0 cm2) estimates at 12 years were 88.1% +/- 3.1%. Freedom from severe @entity339 at 12 years for 114 @entity1 with no @entity339 (maximum regurgitant jet area = 0 cm2) on intraoperative transesophageal echocardiography and 77 @entity1 with @entity339 was 95.3% +/- 2.1% and 82.9% +/- 5.1%, respectively (p = 0.033). CONCLUSIONS: Twelve-year echocardiographic follow-up demonstrates good long-term results of chordal replacement with expanded @entity736 sutures for anterior @entity3454 . To avoid recurrence of regurgitation, a significantly high level of competence of the valve is essential in the repair of anterior @entity3454 .
