Pulmonary Artery

Tricuspid atresia is a congenital anomaly in which the tricuspid valve is absent and the right ventricle is small (hypoplastic).

Pulmonic valve regurgitation occurs when blood leaks abnormally backward from the pulmonary artery through the pulmonic valve into the right ventricle. This can result in right heart failure.

The Bland-White-Garland Syndrome is a congintal coronary anamaly in which the left main coronary artery arises from the pulmonary artery.
