“…These leads are usually implanted subcutaneously, from the lower margin of the ICD pocket along the chest wall, and were reported to give a mean DFT reduction of 20% to 60%. [9][10][11] Juchem et al 16 reported two cases of transvenous coil lead being placed as a subcutaneous array electrode. There is no difference in implantation technique, but the coil portion of the transvenous leads is smaller (8 cm vs 25 cm length) than the coil of an array electrode and is therefore easier to position correctly.…”

Among the implantable cardioverter defibrillator recipients, there is still a subgroup of patients in whom the defibrillation threshold is too high and the maximal shock output of the implantable cardioverter defibrillator can fail to terminate a ventricular arrhythmia. We report a new thoracoscopic minimally invasive approach to place a standard array electrode in the transverse pericardial sinus of a patient implanted with a cardiac resynchronization and defibrillation therapy device with persistent high defibrillation threshold. This approach was developed to achieve very low shock impedance with a consequent increase in the current flow and reduction of defibrillation threshold.
