Abstract:
Pulmonary atresia with intact ventricular septum is a cyanotic congenital heart lesion comprised of complete obstruction of the pulmonary outflow and varying degrees of right heart hypoplasia. There is a wide spectrum of disease from patients requiring minimally invasive transcatheter pulmonary valve perforation/balloon dilation as a neonate and having biventricular circulation, to patients requiring a ductal arterial stent or systemic-to-pulmonary-artery shunt as a neonate and undergoing single ventricle palliation, or even primary heart transplant. Factors determining these pathways include anatomic elements of the right ventricle, and presence, degree and severity of right ventricular-dependent coronary circulation.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Overview of Pulmonary Circulation
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
