IntroductionCardiac lipomas account for about 10% of all primary benign cardiac tumors. Lipomas are composed of mature adipocytes and can form in any part of the heart. Lipomas are encapsulated and well surrounded tumors, and often they are benign and slow growing. Most lipomas occur in the right atrium or left ventricle. Lipomas originating from the sub-endocardium can cause obstruction, and those originating from the myocardium can cause arrhythmias. And in sub-epicardial cases, they can cause pressure on the coronary arteries or the pericardial space. Cardiac lipomas are usually asymptomatic and are therefore often found incidentally. In symptomatic cases, the patient’s symptoms depend on the location of the mass and obstruction in the cavities or valves of the heart.(1, 2)
