Fetal echocardiographic findings were compared with autoptic ones in 11 from 22 fetuses and neonates with prenatal diagnosis of a congenital heart malformation. Pregnancy was interrupted on mother's desire in 7 from these 11 cases and completed by delivery in 4 cases. Diagnosed heart anomalies included ectopia (2), double outlet right ventricle with other malformations (2), tetralogy of Fallot (1), complete atrioventricular canal (1), syndrome of visceral symmetry (levoisomerism) with aortic atresia and common atrium as well as ventricle (1) and pulmonary atresia with a dysplastic tricuspid valve (1). Autoptic verification of a broad spectrum of heart malformations diagnosed in utero showed a developing potential of fetal echocardiography. A prenatal diagnosis of malformation enables to interrupt pregnancy in indicated cases. A complete morphological examination has particular demands on pathologist's attitude and training.
