Balloon valvuloplasty of @entity849 has become the treatment of choice in @entity1 and adults. This is a report about the long term results in adult @entity1 . Forty-six @entity1 (mean age 37 +/- 17 years) with @entity849 were treated between 1984 and 1994 by this method. Thirty-four of 46 @entity1 were re-examined 3 months to 9 years (mean 3.4 years) later by right heart catheterization and echocardiography. These 34 @entity1 were representative for the whole group concerning age, severity of the @entity849 , and acute results after the intervention. The pressure gradient was acutely reduced by balloon valvuloplasty from 86 +/- 35 to 38 +/- 17 mm Hg (p < 0.0001) (n = 46) and was 32 +/- 10 mm Hg (n.s.) (n = 34) at follow-up. Within 3 months after the intervention, 8 of 13 @entity1 with a pressure gradient > or = 100 mm Hg, showed spontaneously further reduction of the gradient due to the resolution of the subvalvular muscular @entity1184 . During a bicycle exercise test with 9 @entity1 , the gradient rose significantly from 29 +/- 10 to 53 +/- 23 mm Hg (p < 0.01) as determined by right heart catheterization. All of these @entity1 had normal cardiac output at rest and during exercise. None had signs of @entity8158 in the electro- or echocardiogram. It is concluded that balloon valvuloplasty of @entity849 is the first line treatment in adults.
