Pulmonary atresia with intact ventricular septum (PA/IVS) is a rare congenital heart disease with a poor prognosis. It displays great anatomical diversity with varying degrees of right ventricular (RV) hypoplasia, which determine the therapeutic approach. Ideally, the goal is to establish a biventricular circulation. This may be achieved through surgical ...
