The selection of an appropriate implantable cardioverter-defibrillator (ICD) type and implantation strategy involves a myriad of considerations. While transvenous ICDs are standard, the rise of non-transvenous options like subcutaneous ICDs and extravascular ICDs is notable for their lower complication rates. Historical preferences for dual chamber ICDs have shifted to single-chamber ICDs. Single-coil ICDs are preferred for easier extraction, and the use of the DF-4 connector is generally recommended. Cephalic cutdown is the preferred venous access technique, while axillary vein puncture is a viable alternative. The right ventricular apex remains the preferred lead position until further evidence on conduction system pacing emerges. Left-sided, subcutaneous ICD implantation is considered reliable, contingent on specific cases. A meticulous perioperative plan, including antibiotic prophylaxis and an antithrombotic regimen, is crucial for successful implantation.
