“…3,4 Because the ductus arteriosus supplies adequate pulmonary blood flow (PBF) in utero, the main pulmonary artery and branch pulmonary arteries are normal in caliber. 8 Intrauterine PV atresia and RVOTO cause substantial "upstream" abnormalities, including maldevelopment of the TV and RV. The RV is hypertrophic with cavity size reduced in 90% of cases and severely hypoplastic in 50% of cases.…”

“…RV and coronary angiography are used to confirm the presence and extent of LV myocardial dependence on the coronary flow from the RV. 4,5,8,20,21 Noninvasive imaging, such as chest computed tomography (CT) may be an alternative to cardiac catheterization in diagnosing coronary artery abnormalities; however, cardiac catheterization remains the preferred diagnostic tool due to the ability to simultaneously preform therapeutic interventions. 3,8,22…”

Pulmonary atresia with intact ventricular septum (PA/IVS) is a rare right-heart obstructive lesion with a wide anatomic and physiologic spectrum of disease, ranging from simple membranous pulmonary valve atresia with a fully developed right ventricle (RV) to a severely hypoplastic RV and ventriculocoronary (RV-coronary) fistulas. Affected neonates are dependent on prostaglandin for adequate pulmonary blood flow. Depending on the severity of disease, treatment options range from transcatheter pulmonary valve perforation and ultimate biventricular repair to staged single-ventricle palliation. Cardiac transplantation is recommended in the most severe cases. This review will discuss the perioperative and anesthetic management of patients with PA/IVS and highlight the challenges in management.
