Most people with pulmonic regurgitation only have a mild or trace amount of leakage through the valve. For them, the outlook is good, and their lifespan should be the same as people without this condition. Moderate leakage also usually has a good outlook with early treatment and diagnosis.
For mild to moderate pulmonary regurgitation, there is no significant impact to survival rates. In severe pulmonary regurgitation, there tends to be increased strain on the right ventricle, which causes abnormal heart rhythms and right ventricle failure.
Pulmonary regurgitation (PR, also called pulmonic regurgitation) is a leaky pulmonary valve. This valve helps control the flow of blood passing from the right ventricle to the lungs. A leaky pulmonary valve allows blood to flow back into the right ventricle before it gets to the lungs for oxygen.
Physiologic trace to mild pulmonic valve regurgitation (also known as pulmonic regurgitation or PR) commonly occurs in normal individuals. Greater degrees of PR are caused by various disorders and can lead to right ventricular (RV) volume overload and right heart failure.
The continuous wave Doppler signal for mild pulmonary regurgitation appears light with a slow deceleration rate. In cases of moderate pulmonary regurgitation, the continuous wave Doppler signal density is moderate, and the deceleration rate varies.
Types of pulmonary valve disease include: Pulmonary valve stenosis. Narrowing of the pulmonary valve reduces the blood flow from the heart to the pulmonary artery and lungs. Pulmonary valve regurgitation. The flaps of the pulmonary valve don't close tightly. Blood moves backward into the right lower heart chamber, called the right ventricle.
Pulmonic (pulmonary) regurgitation (PR) is incompetency of the pulmonic valve causing blood flow from the pulmonary artery into the right ventricle during diastole. The most common cause is pulmonary hypertension. PR is usually asymptomatic. Signs include a decrescendo diastolic murmur.
If pulmonic regurgitation is mild to moderate, there is no significant reduction in survival. However, severe pulmonic regurgitation and persistently elevated RV volume may lead to RV failure propensity for arrhythmias and increased risk of cardiac death.
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.
Pulmonary regurgitation is the leakage of blood from the pulmonary artery back into the right ventricle. It is rare and is infrequently symptomatic. It gradually develops over many years and results in volume overload and right ventricular (RV) dysfunction.
