Overview

Pulmonary atresia can be classified into two forms: with intact ventricular septum and with ventricular septal defect. Additionally, pulmonary atresia with intact ventricular septum can be further classified into type I or type II depending largely on the complexity of the cardiac lesion as characterized by one of two patterns of pathophysiology.
