Repair of neonatal aortic coarctation.
From 1981 to 1991, 146 infants under 1 month of age underwent repair of aortic coarctation. Forty-two had isolated coarctation, 53 had associated ventricular septal defect, and 51 had complex cardiac defects. The principal mode of presentation was congestive heart failure. The mean age at operation was 10.6 days. The technique for repair was left subclavian artery flap angioplasty in 126, resection with end-to-end anastomosis in 14, and a variety of repairs in 6 patients. Concomitant pulmonary artery banding was performed in 62 patients. The overall hospital mortality rate was 11%, and there was a strong association with pre-existing renal failure. The mean aortic clamp time in survivors was 23.9 minutes; mean hospital stay was 13.4 days. Significant restenosis occurred in 16 patients (11%) with an incidence of 10% after subclavian artery flap angioplasty. Eleven patients have undergone reoperation, and 5 were managed successfully with balloon dilatation.
