Long-term follow-up results of balloon valvuloplasty for congenital aortic stenosis: predictors of late outcome.

Abstract

Valvuloplasty carries the risk of development of valve incompetence, which progresses with time. Some patients develop restenosis. The </= 10 year survival after the procedure is excellent, and 56% of patients are free of re-intervention at 8 years. The immediate post-valvuloplasty incompetence grade and transvalvar gradient are the predictors of late re-intervention.
