OBJECTIVES: We attempted to evaluate the role of balloon angioplasty in the treatment of discrete @entity1498 in adolescents and adults, with special emphasis on long-term results. BACKGROUND: Controversy persists over the use of balloon dilation for the treatment of native @entity1498 . METHODS: Between July 1986 and January 1997, 43 consecutive adolescent and adult @entity1 with discrete @entity1498 underwent balloon angioplasty. One- to 10-year follow-up data of 37 @entity1 , including results of cardiac catheterization and magnetic resonance imaging (MRI), form the basis of this study. RESULTS: No early or late @entity204 occurred. Balloon angioplasty produced a reduction in the peak to peak @entity1498 gradient from a mean +/- SD of 69 +/- 24 mm Hg (95% confidence interval [CI] 61 to 76) to 12 +/- 8 mm Hg (95% CI 10 to 14.8) (p < 0.001). Follow-up catheterization 12 months later (37 @entity1 ) revealed a residual gradient of 6.7 +/- 6 mm Hg (95% CI 4.6 to 8.9); 3 (7%) of 43 @entity1 had suboptimal results with development of recoarctation, defined as peak gradient >20 mm Hg, with successful repeat angioplasty. A small @entity439 developed at the site of dilation in 3 (7%) of the 43 @entity1 . MRI follow-up data 1 to 10.8 years (mean 5.2 +/- 2.7) after angioplasty (37 @entity1 ) revealed no new @entity439 or appreciable change in the size of the preexisting @entity439 in the three @entity1 . The blood pressure had normalized without medication in 27 (73%) of 37 @entity1 at follow-up examination. CONCLUSIONS: Balloon angioplasty is safe and effective and should be considered a viable alternative to operation for treatment of discrete @entity1498 in adolescents and adults.
