[Catheter intervention for adult congenital heart diseases].
The efficacy of catheter intervention for adult congenital heart diseases was evaluated in 27 patients aged 20 to 52 years (mean age at catheterization 25 +/- 7 years) from 1986 to 1996. Four patients had pulmonary valve stenosis, four had aortic valve stenosis, three had coarctation of the aorta, 10 had pulmonary artery stenosis, four had cyanotic heart diseases and aorto-pulmonary collateral arteries, one had patent ductus arteriosus, and one had cyanotic heart disease and stenotic Blalock-Taussig shunt. Balloon dilation was successful in all patients with pulmonary valve stenosis, and follow-up evaluation (1-8 years) showed no restenosis in any patients. Balloon dilation was successful in all patients with aortic valve stenosis, and follow-up evaluation (0.5-5 years) showed transvalvular pressure gradient < 50 mmHg. Stenosis was relieved successfully in all patients with coarctation of the aorta, and follow-up evaluation showed no restenosis. Balloon dilation was successful in eight of 13 locations (62%) in patients with pulmonary artery stenosis. Coil embolization was successful in all patients with cyanotic heart diseases and aortopulmonary collateral arteries. In a patient with patent ductus arteriosus, two coils were placed in the ductus arteriosus but were retrieved because hemolysis was observed after the embolization. These data indicate that catheter intervention in young adults with congenital heart diseases is as effective as in children.
