Abstract
Lipomatous hypertrophy of the interatrial septum is an uncommon condition characterised by the excessive deposition of adipose tissue in the interatrial septum. It is diagnosed by the characteristic thickening of the inter atrial septum with sparing of the formen ovale giving rise to a dumbbell shape appearance. Surgical excision is indicated in patients with intractable symptoms due to severely thickened septum. We report a patient who presented with atrial arrhythmia possible due to lipomatous hypertrophy of interatrial septum.
