A heart defect present from birth in which the mitral valve is completely closed off.

Understanding Mitral atresia disorder

Mitral atresia disorder is a heart defect present from birth in which the mitral valve did not form an opening.

GARD describes this as a congenital heart defect marked by complete atresia of the mitral valve. The mitral valve normally lets blood flow from the upper left heart chamber to the lower left chamber. GARD does not list other details.
