Pulmonary Stenosis Overview

What is pulmonary stenosis?
A person with pulmonary stenosis has abnormal narrowing of the pulmonic valve in the heart. A normal pulmonic valve allows blood to flow from the right ventricle of the heart, to the lungs, where it picks up oxygen before returning to the left side of the heart. The pulmonic valve closes to prevent the backflow of blood from the lung, back into the right ventricle of the heart. A narrowed pulmonic valve interferes with the normal flow of blood from the right ventricle to the lung. This places stress on the heart, as it tries to keep up with demand.

What are the symptoms of pulmonary stenosis?
Symptoms of pulmonary stenosis include difficulty breathing, fatigue, rapid pulse, abdominal swelling, swollen neck veins, leg swelling, and foot swelling.

How does the doctor treat pulmonary stenosis?
Treatment may not be necessary for mild pulmonary stenosis. Treatment for moderate to severe pulmonary stenosis includes surgery to repair, or replace, the pulmonary valve.
