Intermediate outcomes of XXXX post-balloon mitral valvotomy.

@entity1 @entity339 @entity955 @entity4794 @entity85
BACKGROUND: Balloon mitral valvotomy is a standard therapeutic modality for managing @entity4794 . Data on intermediate outcomes of this procedure are limited. Thus we investigated the intermediate outcome after balloon mitral valvotomy performed at a large tertiary center in India. METHODS: Case records and follow-up data of 2330 @entity1 who underwent valvotomy from June 1999 to December 2005 were retrieved from the hospital information system and analyzed. RESULTS: The median age of the @entity1 was 32        11 years, 1363 were female including 36 who were pregnant, and 379 were in @entity955 . Follow-up ranged from 1 to 14 years (mean 4.5 years, median 4.0 years). The procedural success rate was 93%. @entity955 , higher functional class, and worse valve morphology were independent predictors of a poor procedural outcome. @entity1 with sinus rhythm had better event-free survival (10.43 years, 95% confidence interval: 10.1-10.7) compared to those with @entity955 (8.17 years, 95% confidence interval: 7.5-8.8). @entity1 who achieved a valve area >1.75   cm(2) had a better event-free survival (11.7 years, 95% confidence interval: 11.4-12.0) than those with a valve area of 1.5-1.74   cm(2) (9.3 years, 95% confidence interval: 9.0-9.7). On multivariate analysis, higher functional class, worse valve morphology, and new significant @entity339 were predictors of a poor outcome. Achieved mitral valve area >1.75   cm(2) was an independent predictor of a good outcome. CONCLUSION: @entity1 with sinus rhythm, less gross @entity85 , and a post-balloon mitral valvotomy area >1.75   cm(2) had better intermediate outcomes.
