title: Intractable ventricular tachycardia in a patient with left ventricular epicardial lipoma.
abstract: Primary cardiac lipomas are rare and are often reported as incidental findings during operations or autopsies. Lipoma-induced arrhythmia, especially ventricular tachycardia (VT), is an unusual complication of primary cardiac lipoma. We describe the case of a 43-year-old woman who presented with VT without any cardiac abnormality except for a left ventricular tumor. Electrophysiologic study (EPS) failed to detect the origin of the arrhythmia, although VT could be induced by EPS preoperatively. Due to suspicion of a relationship between the tumor and the VT, wide tumor resection was performed using cardiopulmonary bypass support. The excised lipoma measured about 10 x 8 x 3 cm and weighed 120 g, and was without pathohistologic evidence of malignant change. The patient was well without further postoperative need for antiarrhythmic drugs at 36 months' follow-up, and VT was no longer inducible on subsequent EPS mappings.
