Pulmonic Insufficiency

What is Pulmonic Insufficiency?

In pulmonic insufficiency, blood ejected into the pulmonary artery during systole flows back into the right ventricle during diastole, causing fluid overload in the ventricle, ventricular hypertrophy, and eventual right­sided heart failure.

Causes of Pulmonic Insufficiency

Pulmonic insufficiency may be congenital or may result from pulmonary hypertension. The most common acquired cause is dilation of the pulmonic valve ring from severe pulmonary hypertension.

Signs & Symptoms of Pulmonic Insufficiency

• May be tolerated for years without problems
• Dyspnea

Diagnostic Tests

Cardiac catheterization shows pulmonic insufficiency, increased right ventricular pressure, and associated cardiac defects.

Chest X-rays show right ventricular and pulmonary arterial enlargement.

Echocardiography can be used to visualize the pulmonic valve abnormality.

Electrocardiography findings may be normal in mild cases or reveal right ventricular hypertrophy.

Treatment

In pulmonic insufficiency, treatment is based on the patient's symptoms. A low-sodium diet and diuretics help to reduce hepatic congestion before surgery. Valvulotomy or valve replacement may be required in severe cases.

Prevention Tips

There are no guidelines for preventing pulmonic insufficiency. If you think you are at risk for Pulmonic insufficiency, talk to your doctor about how to diagnose and manage your symptoms.
