Key result
Surgical excision of lipomatous interatrial septum hypertrophy prevents atrial flutter recurrence, though AF persists.
Why the study?
Lipomatous hypertrophy of the interatrial septum rarely causes clinical sequelae and arrhythmia is an unusual complication.
Case Report (n=1)
Extreme lipomatous hypertrophy of the interatrial septum can cause difficult-to-treat atrial arrhythmias, which can be diagnosed with multimodal imaging and may require surgical excision.
May warrant surgical excision for refractory atrial flutter in lipomatous hypertrophy of the interatrial septum; hypothesis-generating given single-case evidence.
Lipomatous hypertrophy of the interatrial septum (LHIS) rarely causes clinical sequelae and is often reported as an incidental finding on cardiac imaging. Arrhythmia is an unusual complication of LHIS, although other tumors have been reported to cause arrhythmias by mass effect or tissue invasion.1 We present an unusual case of atrial arrhythmias associated with a large atrial mass that was subsequently confirmed to be LHIS.

Brienesse et al. (2021) conducted a case report in Lipomatous hypertrophy of the interatrial septum (LHIS) with atrial tachycardia (n=1). Surgical excision and biatrial cryoablation was evaluated on Arrhythmia recurrence. Surgical excision of a large lipomatous hypertrophy of the interatrial septum prevented atrial flutter recurrence at 6 months, though paroxysmal atrial fibrillation persisted.
