What is pulmonary vein stenosis?

Also known as: PVS

Your heart pumps blood to your lungs to pick up oxygen. This oxygen-rich blood then travels back to your heart through the pulmonary veins. In pulmonary vein stenosis (PVS), one or more of these veins become narrowed or blocked, making it harder for blood to flow smoothly and increasing pressure in your lungs.

PVS is a rare and often unrecognized yet serious disease that causes a blockage of the blood vessels that bring the blood from the lungs back into the heart. It often affects babies born prematurely or with other cardiac conditions, however, it can also affect otherwise healthy patients.
