Simultaneous subcutaneous implantable cardioverter-defibrillator and leadless pacemaker implantation for patients at high risk of infection: a retrospective case series report

Wireless Device Therapy in Hypertrophic Cardiomyopathy Using the Combination of a Leadless Pacemaker and a Subcutaneous Defibrillator: A Report with 2-year Follow-up of Two Patients

Cardiac implantable electronic devices (CIEDs) are essential tools in cardiology for tackling rhythm disturbances and have come a long way over the last decades. Technology is shifting toward leadless devices that spare the complications and limitations of traditional intravascular CIEDs. Herein, we report the simultaneous implantation of a leadless pacemaker (LP) and a subcutaneous implantable cardioverter-defibrillator (S-ICD) in two patients with hypertrophic cardiomyopathy, as well as their 2-year follow-up results, while explaining the preventive measures taken to steer around unwanted device interaction. Implantation of an S-ICD with an LP is reserved for unique cases but is a feasible approach when there is a contraindication for intravascular CIED implantation. Furthermore, this technique may be used in younger patients with cardiomyopathies in whom multiple generator replacements are expected, along with their known adverse effects.
