ABSTRACT
Subcutaneous-to-extravascular implantable cardioverter-defibrillator exchange can create a practical challenge: the existing subcutaneous generator pocket lies posteriorly, whereas the new extravascular generator site is planned more anteriorly. In this case, fluoroscopic planning showed adjacent generator sites, allowing a single intervening pocket incision. Bidirectional dissection enabled subcutaneous generator removal and extravascular pocket creation, while separate deep-layer closure avoided a large continuous pocket and preserved standard extravascular generator positioning.
