A. Initial ICD-DR system consisted of defibrillator lead Medtronic Sprint 6935M62 (RV) and Medtronic 3830-74cm lumenless lead designed for His bundle pacing (His) connected to atrial channel and fixed in intraventricular septum; B. Medtronic 3830-74cm lumenless lead (His) grasped (lock) in the right atrium with Needle Eye Snare (NES), (COOK MEDICAL LLC Bloomington, USA) introduced via femoral approach; C. The new CRT-D + HBP system at discharge; LV : left ventricular lead.

Present ICD-DR system consisted of defibrillator lead and lumenless lead designed for His bundle pacing fixed in the intraventricular septum (Fig. 1A). Given the relatively short lead dwell time, its position was secured by gripping the lead in the right atrium with a Needle Eye Snare, introduced via the femoral approach (Fig. 1B). Finally, the ICD lead was extracted and a new CRT-D + HBP system was implanted (Fig. 1C).
