Anterograde balloon valvuloplasty for the treatment of neonatal critical XXXX .

@entity1 @entity339 @entity11459 @entity1699 @entity337 @entity472
We report our experience with anterograde balloon valvuloplasty in 17 neonates treated between November 1996 and June 2001 for critical @entity472 . @entity1 with @entity1699 were excluded. Anterograde balloon valvoplasty of the aortic valve was possible in all 17 @entity1 . The mean peak systolic gradient prior to cardiac catheterization was 73 mm Hg (range, 30-117 mm Hg) and decreased to 37 mm Hg (range, 21-60 mm Hg) after the dilation. @entity337 after balloon valvoplasty was absent or mild in 14/17 @entity1 , moderate in 2 @entity1 , and severe in 1 @entity1 . There was no mortality or echocardiographic evidence for aortic cusp perforation or @entity339 associated with the procedure. Redilation was necessary in 3/17 @entity1 . Two @entity1 are awaiting elective Ross operation. One @entity1 with @entity11459 died at 11 months of age. Anterograde balloon valvoplasty can be safely and effectively performed to palliate neonates with critical @entity472 .
