Imaging description Atrial septal aneurysms (ASA) appear as a thin-walled, round or lobulated outpouching located at the fossa ovalis. They are formed by redundant tissue of the fossa ovalis that protrudes ≥ 10–15 mm beyond the plane of the interatrial septum with a base ≥ 15 mm in width (Figure 18.1). The atrial septum is the membrane that separates the left and the right upper chambers of the heart (the atria). By definition, when the atrial septum travels abnormally into either or both of the atria with each heartbeat, it is considered to have an aneurysm.
