S-ICD Extraction Procedure
All S-ICD extraction procedures were performed in an electrophysiology
lab under general anesthesia, monitored anesthesia care, or conscious
sedation. The patient was positioned in the same fashion as for S-ICD
implantation. The generator was accessed by making an incision over the
existing scar, and sharp or blunt dissection was performed until the
generator was visualized. After the generator was disconnected from the
lead, another incision was made over the subxiphoid scar to release the
suture sleeve. If a three-incision technique was used for S-ICD
implantation, a third incision was made over the superior sternum to
release the distal lead suture. After all lead tie-down sutures were
cut, the S-ICD was removed with manual traction. No transvenous lead
extraction tools were required for successful removal. All incisions
were closed in three layers following system extraction.
