Cardiac Lipoma : Clinical Features
Clinical Features: Small cardiac lipomas are asymptomatic and discovered incidentally at autopsy. Larger subepicardial tumors grow into pericardial cavity causing effusions and constrictive pericarditis. Larger subendocardial tumors can bulge into cardiac chambers and interfere with the blood flow leading to heart failure. Rare cases are associated with arrhythmias and can cause sudden death. Cardiac CT and MRI are the best diagnostic tools as they can identify fat with high accuracy. The image shows a resected right atrial lipoma along with a portion of the atrial septum.
