Congenital heart disease and its association with other congenital malformations found at autopsy.
The objective was to determine if a study of other malformations found autopsy in patients with congenital heart disease would contribute to an understanding of the mechanisms involved in the formation of these anomalies. In a large general hospital autopsies in children with congenital heart disease were selected, and the different cardiopathies were divided into 3 groups: those with isolated heart lesions, those with single gene mutants, as well as chromosome malformations, and those with idiopathic malformations not associated with a genetic syndrome. Because the cardiopathies most often associated with genetic syndromes were the septal defects in general (p = .001), it was presumed that these are influenced to a considerable extent by genetic factors. The association of left heart hypoplasia and coarctation of the aorta with multiple idiopathic malformations, particularly in the lower half of the body (p = .002), suggests that the latter may be due to vascular disruptions, because of the interruption of the flow of oxygenated blood in the embryo-fetus produced by these heart defects. Cranial defects were not associated with left heart obstruction, and are therefore unlikely to be produced by vascular disruption.
