What is Valvar Atresia?
A heart defect that occurs when the heart valve opening does not develop at all, preventing blood from passing from an atria to a ventricle, or from a ventricle to the pulmonary artery or aorta. Blood must find an alternate route, usually through another existing congenital (present at birth) defect such as an atrial septal defect or a ventricular septal defect.
