The outcome of pulmonary atresia with an intact ventricular septum (PAIVS) remains inferior compared with other complex congenital heart defects such as transposition of the great arteries. This may reflect partly on the morphologic heterogeneity of this condition and partly on the interpretation of this morphology by different institutions.
The morphologic heterogeneity in PAIVS encompasses a spectrum of lesions, including hypoplasia of the right ventricle (RV) and tricuspid valve, abnormal coronary circulation, and pulmonary atresia itself. Ideally, surgery should optimize the growth of the RV and the tricuspid valve without compromising the coronary circulation and ventricular function. In addition, several physiologically based management protocols and algorithms are not supported by surgical outcome.
A particular challenge in planning a strategy for the
