Approaches to the demonstration of congenital heart disease.

Abstract

Advances in antenatal screening techniques have increased the interest in obtaining a detailed pathological correlation with the ultrasonographic findings obtained before death. As a consequence, inadequacies in traditional methods used by pathologists to display congenital malformations have been brought to light. We describe a simple technique of inflation and wax impregnation for the permanent proof of congenital heart defects that can be used in routine perinatal necropsies.
