Pulmonary atresia with intact ventricular septum and systemic-pulmonary collateral arteries

Pulmonary atresia with intact ventricular septum and major systemic-pulmonary collateral arteries is a very rare congenital heart lesion with dismal natural history. Herein we report on a case of pulmonary atresia with intact ventricular septum with hypoplastic right ventricle, very small confluent pulmonary arteries, absent arterial duct, and pulmonary blood flow exclusively provided by bronchial-type systemic-pulmonary collateral arteries that was successfully treated at our institution.
