Right parasternal electrode placement for an S-ICD may be a feasible alternative in specific patients based on thoracic anatomy, although standard left-sided placement should generally not be outweighed.
The totally subcutaneous implantable cardioverter-defibrillator (S-ICD) is an entirely novel defibrillation device that avoids the direct contact of device electrodes with the heart and the cardiovascular system. Here, we present a particular case of a young woman with congenital long-QT syndrome in which we implanted the electrode alternatively, right parasternally. This decision was based on the thoracic anatomy of the patient and on findings of a model of S-ICD electrodes in an adult torso. In conclusion, in some patients an alternative subcutaneous electrode position may be carefully considered but should not be taken to outweigh the standard left-sided placement.

Zumhagen et al. (2011) conducted a case report in Congenital long-QT syndrome (n=1). Totally subcutaneous implantable cardioverter-defibrillator (S-ICD) with right parasternal electrode placement was evaluated. An alternative right parasternal subcutaneous electrode position for an S-ICD was successfully used in a young woman with congenital long-QT syndrome based on her thoracic anatomy.
