Ontology: Atrial Septal Defects (C0018817)

Definition (NCI) A congenital disorder characterized by the presence of a defect (opening) in the septum that separates the two atria of the heart. The atrial septal opening that is present in the fetus and normally closes within weeks or months after birth.

Definition (CHV) defect in the wall between the lower chambers of the heart
Definition (MSH) Developmental abnormalities in any portion of the ATRIAL SEPTUM resulting in abnormal communications between the two upper chambers of the heart. Classification of atrial septal defects is based on location of the communication and types of incomplete fusion of atrial septa with the ENDOCARDIAL CUSHIONS in the fetal heart. They include ostium primum, ostium secundum, sinus venosus, and coronary sinus defects.
