Orpha code: 99107OMIM code:

Definition

A rare congenital non-syndromic heart malformation characterized by an abnormal protrusion of the interatrial septum into the right or left atrium, or both, during the cardiorespiratory cycle. The defect may be limited to the fossa ovalis or involve the entire septum. It can present as an isolated finding but is more often associated with interatrial shunts, in particular patent foramen ovale. Clinically it increases the risk of peripheral arterial embolism and stroke.
