[Aortic coarctation and associated abnormalities in the first year of life. Echocardiographic diagnosis].

Thirty-eight cases of "Aortic Coarctation Syndrome" presenting in the first year of life (66% under 3 months of age) were studied with cross-sectional echocardiography. Direct imaging of the coarctation was achieved in 75% of cases. Patent ductus arteriosus was present in 60% (80% before three months). Associated anomalies were present in 63%; VSD 29%, Aortic stenosis 16%, Mitral stenosis 16%, AV Canal 5%, Taussig Bing type of DORV 5%, Corrected transposition with VSD 3%, Ebstein anomaly 3%, Univentricular A-V connection 3%. The results were compared with angiographic and/or surgical and/or autoptic findings. The echocardiographic diagnosis proved to be very reliable in most cases. The policy of sending to surgery most neonates and infants with coarctation of the aorta without preoperative catheterization is discussed.
