Clinical Evaluation of 242 Operated Cases With Congenital Heart Disease in Our Hospital

From June 1989 through December 1994, we experienced 242 operated cases with congenital heart disease, aged from 0 days to 15 years. All were admitted to our hospital. The incidence of surgical death was 8.3% (20 cases). Most of the 20 deaths belonged to the groups of neonates and infants under three months of age. Of the 242 operated cases, we performed percutaneous transluminal angioplasty (PTA) for 9 cases with postoperative stenotic lesions and percutaneous transluminal valvuloplasty (PTV) for 1 case with congenital aortic valve stenosis. PTA was effective in 3 patients with postoperative anastomotic stenosis after Blalock-Taussig shunt, 3 with aortic recoarctations after surgical repair of coarctation of the aorta and 1 with postoperative aortic stenosis after surgical repair of interruption of the aortic arch, but was not effective in 2 patients with pulmonary stenosis following total correction of transposition of the great arteries and truncus arteriosus communis. PTV was ineffective in one patient with congenital aortic valve stenosis. PTA, one of the interventional cardiac catheterizations, is a safe and effective procedure and may improve the prognosis of patients with stenotic arterial lesions after cardiac surgery.
