Tree Number(s): C14.240.400.200; C14.280.400.200; C16.131.240.400.200
Unique ID: D003310
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D003310
Scope Note: 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.
