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).

Lipomatous hypertrophy of the interatrial septum (LHIS) is a relatively uncommon disorder of the heart characterized by benign fatty infiltration of the interatrial septum. It is commonly found in elderly and obese patients as an asymptomatic incidentally discovered finding.

interatrial septum (septum interatria´le cor´dis) the partition separating the right and left atria of the heart; called also atrial septum. interradicular septum interalveolar septum (def. 1). The interatrial septum is the wall that separates right from left atrium …a partition known as the interatrial septum; the lower chambers, the ventricles, are separated by the interventricular septum. The atria receive blood from various parts of the body and pass it into the ventricles. The ventricles, in turn, pump blood to the lungs and to the remainder of the body.

The upper chambers, the atria, are separated by a partition known as the interatrial septum; the lower chambers, the ventricles, are separated 

LA = left atrium; IAS = interatrial septum; IVC = inferior vena cava; SVC = superior vena cava; RA = right atrium.) Rotation of the multiplane TEE probe to 123° demonstrated thickening of the upper and lower portions of the IAS, with sparing of the fossa ovalis, a pattern characteristic of lipomatous hypertrophy, and a 2.5-cm mass of similar echogenicity in the RA, adjacent to the IVC. A thin partition or membrane that divides two cavities or soft masses of tissue in an organism: the nasal septum; the atrial septum of the heart.
