A 52-year-old man experienced a subcutaneous implantable cardioverter-defibrillator (S-ICD) inappropriate shock due to electrode tip decubitus. The device, implanted two years before with a three-incision technique, was extracted, and a new electrode was implanted along the contralateral parasternal line with a two-incision technique, in a one-stage procedure. One-year follow-up was eventless. Early S-ICD electrode extraction and reimplantation during the same procedure is effective and should be considered as soon as initial signs of decubitus appear to avoid inappropriate shocks. A two-incision technique should be preferred to reduce the risk of electrode tip decubitus.
