ABSTRACT BACKGROUND: Three incisions in the chest are necessary for the implantation of the entirely subcutaneous implantable defibrillator (S-ICD). The superior parasternal incision is a possible risk for infection and a potential source of discomfort. A less invasive alternative technique of implanting the S-ICD electrode avoids the superior parasternal incision: The two incision technique. OBJECTIVE: In this prospective cohort study, we sought to evaluate the safety and efficacy of the two incision technique for the implantation of the S-ICD. METHODS: Consecutive patients who received a S-ICD between October 2010 and December 2011 were implanted using the two incision technique, which positions the parasternal part of the S-ICD electrode using a standard 11 French peel-away sheath. All patients were routinely evaluated for at least one year for complications and device interrogation at the outpatient clinic. RESULTS: Thirty-nine patients (46% male, mean age 44±15 years) were implanted with a S-ICD using the two incision techniques. During a mean follow-up of 18 months (range 14-27) no dislocations were observed and there was no need for repositioning of either the ICD or the electrode. No serious infections occurred during follow-up except for two superficial wound infections of the pocket incision site. Device function was normal in all patients and no inappropriate sensing occurred related to the implantation technique. CONCLUSION: The two incision technique is a safe and efficacious alternative for S-ICD implantations and may help to reduce complications. The two incision technique offers physicians a less invasive and simplified implantation procedure of the S-ICD.
