HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:A bulging of the interatrial septum towards one side. In adults, atrial septal aneurysm can be defined as a protrusion of the aneurysm of >10 mm beyond the plane of the atrial septum as measured by transesophageal echocardiography.
Comment:Atrial septal aneurysm formation may be secondary to raised interatrial pressure gradients, producing a bulging septal shift toward the low-pressure side. However, it has been also found in patients with normal atrial pressures, suggesting a primary (congenital) malformation.
Synonyms:narrow_synonym: Atrial septal aneurysm
