Overview
Overview
Although atrial septal defect ostium secundum defects occur sporadically, they are associated with and occur with higher frequency in certain genetic disorders.
Pathophysiology
Pathophysiology
Associated Conditions
Most of ostium secundum ASDs occur sporadically. However, ostium secundum ASD has been found to occur with increased frequency in association with some genetic disorders including:
- Holt-Oram (heart-hand) syndrome
- Down syndrome
- Noonan syndrome
- Treacher Collins syndrome
- Thrombocytopenia-absent radii (TAR) syndrome
- Mitral valve prolapse: 10% to 20 % of individuals with ostium secundum ASDs also have mitral valve prolapse.[1]
