Cardiac Lipoma : Introduction

Comments:
Introduction: Cardiac lipomas are rare and make up <0.5% of all cardiac tumors. They originate in the epicardium (more commonly) or endocardium and can arise anywhere in the heart with a predilection for left ventricle, right atrium and atrial septum. Rare intramyocardial lipomas have been reported. Another rare location is cardiac valves. Most cardiac lipomas are solitary. Multiple lesions have been described in tuberous sclerosis.
