CTICasesPrimum Atrial Septal Defect (ASD)
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
Large pulmonary arteries, a large primum atrial septal defect, and a single valve plane with some irregularity of the anterior leaflet of the mitral valve. Extensive left-to-right shunting across the ASD was observed, with a Qp:Qs ratio of approximately 2.8:1 to 3:1.
Key takeaways
Primum ASDs are a form of congenital heart disease, often associated with a cleft in the anterior leaflet of the mitral valve. Large shunts can lead to significant pulmonary overcirculation. It is notable for a patient to present with an undiagnosed large primum ASD in middle age.
