Pulmonary (or pulmonic[4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent[5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole.[6] While a small amount of backflow may occur ordinarily, it is usually only shown on 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.[medical citation needed] If it is secondary to pulmonary hypertension it is referred to as a Graham Steell murmur.[7]
