Post mortem radiology in children with congenital heart disease.

Contrast radiology has valuable applications in routine necropsy practice. Contrast radiology was used to study the vascular anatomy in four normal fetuses, in five children with cardiovascular malformations, and in two hearts prepared by the perfusion fixation method. A contrast radiograph provides permanent documentation of anatomical associations before they are disrupted by dissection and permits a planned approach to the necropsy. While these injection studies are seldom undertaken by pathologists because they are felt to be too difficult and time-consuming, contrast studies should form part of the post mortem investigation of children with congenital heart disease, even when angiography has been performed in life.
