Clinical Information
- A malformation of the heart in which the embryonic common pulmonary vein was not incorporated into the left atrium leaving behind a perforated fibromuscular membrane bisecting the left atrium, a three-atrium heart. The opening between the two left atrium sections determines the degree of obstruction to pulmonary venous return, pulmonary venous and pulmonary arterial hypertension.
- A rare congenital abnormality of the heart characterized by the presence of three atria. The right or left atrium is divided into two parts by fibromuscular tissue or a membrane. It may be associated with other heart congenital abnormalities.
