Approximately 15,000 cases of superior vena cava (SVC) obstruction are diagnosed in the United States annually. Malignancies (primarily lung cancer) are the underlying cause of 80-85% of cases, leaving 15-20% caused by various benign conditions, including sclerosing mediastinitis (the diagnosis in our case).

Superior Vena Cava Electrode

Background A unipolar defibrillation system using a single right ventricular (RV) electrode and the active shell or "CAN" of the implantable cardioverter-defibrillator itself situated in a left infraclavicular pocket has been shown to be as efficient in defibrillation as an epicardial lead system. The purpose of this study was to determine whether defibrillation efficacy can be improved further...
