Pulmonic regurgitation
-
Pulmonic (pulmonary) regurgitation is leakage of blood backward through the pulmonary valve each time the right ventricle relaxes.
Pulmonic regurgitation usually does not cause symptoms.
Doctors make the diagnosis because of physical examination findings, and they use echocardiography to confirm the diagnosis.
The underlying disorder is treated.(See also Overview of Heart Valve Disorders.)
The pulmonic valve is in the opening between the right ventricle and the blood vessels going to the lungs (pulmonary arteries). The pulmonic valve opens as the right ventricle contracts to pump blood into the lungs. When the pulmonic valve does not close completely, some blood leaks backward from the pulmonary arteries into the right ventricle, termed regurgitation.
The most common cause of pulmonic regurgitation isAbnormally high blood pressure in the lungs (pulmonary hypertension)
The high pressure stresses the valve, causing it to leak.
Much less common causes areInfection of the valve (infective endocarditis)
Pulmonary artery enlargement
A birth defect of the valve
Surgery to repair a heart defectPulmonic regurgitation usually causes no symptoms. Sometimes people develop swollen ankles or fatigue.
