A Rare Case of a Primary Cardiac Tumor Presenting as Fatal Ventricular Tachycardia

Abstract

Primary cardiac tumors are extremely uncommon. Here, we report the case of a patient with a primary left ventricular interstitial tumor presenting with hemodynamically unstable ventricular tachycardia. In response to hemodynamically unstable ventricular tachycardia, an implantable cardioverter-defibrillator was inserted. One month after defibrillator implantation, the patient developed episodes of high ventricular tachycardia that could not be effectively terminated by catheter radiofrequency ablation, thus further confirming that the ventricular tachycardia was induced by the left ventricular interstitial tumor. The patient is doing well on medical therapy to date.
