Pulmonic Regurgitation

Pulmonic regurgitation, also known as pulmonary regurgitation, is the backward flow of blood from the pulmonary artery, through the pulmonary valve, and into the right ventricle of the heart during diastole. While a small amount of pulmonic regurgitation may occur in healthy individuals, it is usually detectable only by an echocardiogram and is harmless. More pronounced regurgitation that is noticed through a routine physical examination is a medical sign of disease and warrants further investigation.
