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.

A 56-year-old asymptomatic woman with a history of hypertension and hyperlipidemia was referred to echocardiographic examination. Lipomatous hypertrophy of the interatrial septum is a benign cardiac mass that should be considered as part of the differential diagnosis for any atrial cardiac tumour. In the reported case, this lesion was initially suspected to be malignant and the patient was thus referred directly to cardiac surgeons for surgical removal.

The interatrial septum forms during the first and second months of fetal development. Formation of the septum occurs in several stages. The first is the development of the septum primum, a crescent-shaped piece of tissue forming the initial divider between the right and left 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. In all patients the interatrial septum had a bilobed or dumbbell shape that is typical of LHIS (Figs.

Key words: lipomatous hypertrophy of the interatrial septum, atrium, atrial septum, lipomatosis Abstract Lipomatous hypertrophy of the interatrial septum is a benign disorder that is characterized by the fat deposition in the interatrial septum. It typically occurs in elderly, obese patients and may cause arrhythmia.

Lipomatous hypertrophy of the interatrial septum is a rare, but increasingly recognized, anomalous developmental or neoplastic lesion of the heart. This entity was first described in 1964 at autopsy and is identified before death based on its distinctive characteristics on echocardiography, computed tomography, and magnetic resonance imaging.

The division deepens, the septum divides into two lamellæ, and finally two cells are formed. The Elements of Bacteriological Technique | John William Henry Eyre For each myotome there is a single nerve, … 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).
