Pulmonary Atresia with Intact Septum



In pulmonary atresia with an intact septum, the right ventricle is unable to eject blood into the pulmonary circulation.  Suprasystemic pressures result in the RV forcing the blood into the primitive venous system draining the right ventricle and the blood then flows retrograde into the coronary arteries which are at a lower pressure.
