Eight hundred twenty-two balloon pulmonary valvuloplasties were reported to the Valvuloplasty and Angioplasty of Congenital Anomalies Registry. Before and after systolic outflow gradients were recorded in 784 valvuloplasties, and the gradient decreased from 71 +/- 33 to 28 +/- 21 mm Hg. The sites of residual obstructions could be ascertained in 196 patients. In these, the total systolic outflow gradients decreased from 85 +/- 41 mm Hg to 33 +/- 27 mm Hg. Of this total residual gradient, 16 +/- 15 mm Hg was transvalvar and 18 +/- 24 mm Hg was infundibular. The degree to which infundibular obstruction subsequently resolved was not determined in this study. The procedure was less effective in reducing outflow gradients in patients with dysplastic valves with or without Noonan's syndrome. There were 5 major complications (0.6%), including 2 deaths (0.2%), a cardiac perforation with tamponade (0.1%) and 2 tricuspid insufficiencies (0.2%). There were 11 minor complications (1.3%) and 21 incidents (2.6%). The incidence of major complications, minor complications and incidents was inversely related to age; it was substantially higher in infants and, in particular, neonates. Balloon pulmonary valvuloplasty is a safe and effective method of lowering pulmonary outflow gradients in infants, children and adults. Small transvalvar and varied infundibular gradients commonly are present at the end of the procedure. Assessing the full effect of the procedure requires intermediate-term follow-up and assessing the duration of relief requires long-term follow-up.
