Coarctation of the aorta in infants and neonates: results and assessment of prognostic variables.
From 1984 until 1994, 75 consecutive patients younger than 12 months of age were operated on for coarctation of the aorta. We retrospectively analyzed predictive factors for morbidity and mortality, and also interaction between surgical procedures and recoarctation. Surgical procedures were as follows: resection with a traditional end-to-end (E-E) anastomosis in 55 patients (73.3%), prosthetic patch aortoplasty (PPA) in 12 patients (16%) and subclavian flap aortoplasty (SFA) in 8 patients (10.7%). Early mortality was 9.33% (7 patients). Logistic regression analysis proved that age at operation, associated anomalies of heart, type of coarctation, aortic arch hypoplasia and pulmonary banding were independent predictors of hospital death. Late mortality occurred in 7 patients (10.3%). Associated anomalies of heart were an independent prognostic factor for late mortality. Actuarial freedom from recoarctation at 1 year was 91% [confidence limits (CL): 82% to 97%] and 5 years were 74% (CL: 67% to 86%). Immediate postrepair gradient was equal after E-E anastomosis and other procedures. We conclude that the treatment of first choice in the management of coarctation of the aorta in infants is E-E anastomosis.
