Prenatal diagnosis of pulmonary atresia with ventricular septal defect.

Pulmonary atresia with ventricular septal defect (PA-VSD) is a rare complex congenital heart defect. Major artery-pulmonary collateral arteries (MAPCAs) are characteristic of PA-VSD. Prenatal diagnosis can be achieved in most cases of PA-VSD with recent advances in echocardiography. However, it is extremely rare that all MAPCAs can be observed on the echocardiograph. Here, we report a case of prenatally diagnosed type C PA-VSD in which all the MAPCAs could be seen on the echocardiograph, with the diagnosis supported by autopsy evidence.
