[The sex distribution of congenital cardiopathies].
For 17 years, 4150 infants and children under 13 years of age with final diagnosis of well defined congenital heart disease were studied and the pattern of sex differences are reported. In general, the sex distribution was equal: 2108 males (50.8%) and 2042 females (49.2%) with a male to female ratio of 1.03. Male sex predominance was marked for the following specific lesions: aortic stenosis (valvar and subvalvular) (70%), coarctation of the aorta (66%), transposition of the great arteries (60%), univentricular heart (76%), tricuspid atresia (63%), Ebstein anomaly (76%), hypoplastic left heart syndrome (85%), vascular rings (77%) and right midventricular stenosis (70%). Female sex predominance was marked for the following specific lesions: Persistent ductus arteriosus (72%), atrioventricular septal defects (62%) supravalvular aortic stenosis (71%) and isolated infundibular pulmonic stenosis (80%). A more balanced sex distribution was confirmed for cases of congenital rubella syndrome with persistent ductus arteriosus as isolated cardiovascular malformation (56%). The Importance to establish the sex dominance is emphasized as predictive of recurrence risk of congenital heart disease.
