Living with Congenital pulmonary veins atresia or stenosis

A condition in which the veins that carry blood from the lungs back to the heart are narrowed or blocked.

Understanding Congenital pulmonary veins atresia or stenosis

Congenital pulmonary veins atresia or stenosis is a condition in which the blood vessels that bring oxygen-rich blood from the lungs to the heart are blocked or narrowed.

It can affect one vein but often affects several. Stenosis means the vein walls thicken and narrow. The condition is progressive, so a vein can become fully blocked over time. Most often all the pulmonary veins of one lung are affected, which can cause high blood pressure in the lungs (pulmonary hypertension). GARD lists onset in childhood.
