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

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