Primary cardiac tumors are rare and lipoma at interventricular septum is rarer. Most of the cardiac tumors are diagnosed
incidentally on noninvasive imaging. The clinical manifestations of them depend on its anatomic location. Here we are
discussing about a 35-year-old female, who presented with complaints of palpitation, dyspnoea and occasional dizziness
for 6 months. On transthoracic echocardiography and Magnetic Resonance imaging (MRI) evaluation, a large mass of
5.4x5.9x6.5 cm in size at interventricular septum was detected. The mass was partially obstructing right ventricular
outflow tract (RVOT). As the mass was large, the surgical resection had to be performed via both transtricuspid valve and
transpulmonary artery (PA) approach to avoid residual outflow tract obstruction. Aorta was opened to rule out extension
of the mass to left of septum. Histology confirmed the diagnosis of lipoma.
