To the Editor To ensure defibrillation effectiveness with the subcutaneous implantable cardioverter defibrillator (S-ICD), the system must be adequately positioned. The widely adopted two-incision intermuscular implantation technique avoids the superior parasternal incision, and uses an intermuscular pocket for the generator between the serratus anterior and the latissimus dorsi muscles. The aims of this study were to assess the mid-term adequacy of the S-ICD system position in patients in whom an SICD was implanted by means of the two-incision intermuscular technique, and to evaluate the stability of the system by comparing chest radiographs taken immediately after implantation and on 12-month followup examination.

Bisignani et al. (2022) conducted a letter in Subcutaneous implantable cardioverter defibrillator (S-ICD) implantation. Two-incision intermuscular implantation technique for S-ICD vs. Baseline (radiographs immediately after implantation) was evaluated on Adequacy of the S-ICD system position and stability comparing chest radiographs immediately after implantation and at 12 months. The 1-year stability and position adequacy of the subcutaneous defibrillator implanted with the intermuscular two-incision technique was evaluated, though no quantitative results are provided in the abstract.
