IMPLANTATION OF A SUBCUTANEOUS LEAD ARRAY IN COMBINATION WITH A TRANSVENOUS DEFIBRILLATION ELECTRODE VIA A SINGLE INFRACLAVICULAR INCISION

Occasional patients have excessive defibrillation energy requirements despite appropriate transvenous defibrillation lead position and modif ication of defibrillation waveform and configuration. Preliminary data suggest that use of subcutaneous defibrillation electrode arrays with nonthoracotomy systems is associated with a substantial reduction in defibrillation threshold. The current operative approach to subcutaneo us lead array implantation involves the use of a separate left chest i ncision. We present two cases in which implantation of a subcutaneous lead array in combination with a transvenous defibrillation electrode was performed via a single infraclavicular incision and associated wit h a reduction in defibrillation threshold. Such an approach simplities implantation and avoids the potential morbidity of the additional inc ision required of a left interal chest approach.
