Repetitive ventricular tachycardia triggered by a giant benign cardiac lipomyoma.

Cardiac lipomyomas are tumors that may produce various signs and symptoms, including life threatening ventricular tachycardia (VT), often requiring surgical resection and/or catheter ablation. Here we report on a 35-year-old female patient with longstanding repetitive VT in the setting of a large cardiac lipomyoma. Diagnostic testing included non-invasive approaches including ECG, echocardiography and CMR. She then underwent electroanatomic mapping, which provided additional information. The patient ultimately underwent partial resection of the tumor. Postoperatively, long term ambulatory ECG showed VT suppression without anti-arrhythmic or catheter ablation for VT.
