The pulmonary valve is one of four valves that regulate blood flow through the heart. The pulmonary valve opens so blood can flow out. It then closes to ensure blood is only moving forward. In pulmonary valve disease, the pulmonary valve may not be closing properly (regurgitation), may be narrowed (stenosis), or may be missing (atresia).
To address either condition, pulmonary valve surgery (repair and/or replacement) can be performed. Pulmonary valve surgery is performed through open-heart surgery.
