Objectives

Narrative objectives1

We will conduct a multicenter collaborative study to evaluate the safety and efficacy of implanting the Durata ICD lead (Abbott) in the interventricular septum using a delivery catheter-guided approach. The study will assess the imaging-based success rate of septal placement, lead parameters, and defibrillation thresholds. In addition, outcomes will be compared with those of non-septal lead placements. Furthermore, cases in which the same lead was previously implanted using the conventional stylet-delivery technique will serve as a control group, allowing comparative analysis of the proportion of successful septal placements, procedural safety, subsequent clinical management, and long-term prognosis.

Assessment

Primary outcomes

Prevalence of true septal ICD lead implantation based on an imaging modality.

Key secondary outcomes

Lead parameters (threshold, sensing, and impedance) at six months postoperatively, shock impedance, defibrillation threshold, paced QRS duration, incidence of lead-related complications, antitachycardia pacing and defibrillation success rates for ventricular arrhythmias, occurrence of atrial fibrillation, and all-cause mortality and heart failure hospitalization during two years after implantation.

Key inclusion criteria

- Patients at participating institutions who underwent transvenous implantation of an ICD or CRT-D (cardiac resynchronization therapy defibrillator) using the Abbott Durata ICD lead between January 2020 and the date of study approval, and who either have a prior history of chest CT imaging or newly provided informed consent for additional CT imaging at the time of data access after study approval (retrospective cohort).
- Patients at participating institutions who will undergo ICD or CRT-D implantation using the Abbott Durata ICD lead and have provided informed consent for CT imaging (prospective cohort).
- Newly implanted device cases.
- Patients aged 18 years or older, regardless of sex.
- The type of ICD lead shall be limited to active-fixation (screw-in) leads.
- Patients who have provided written informed consent to participate in this study.

Key exclusion criteria

- Patients who did not provide informed consent to participate in this study.
- Cases in which a tined lead was used.
- Cases in which the implanted ICD lead was not an Abbott Durata ICD lead.
- Patients with a previous history of defibrillation lead implantation, in whom the lead was extracted and subsequently reimplanted.
- Upgrade cases from a conventional pacemaker system.
- Cases in which a subcutaneous defibrillation lead system was used.
- In the retrospective cohort, cases without prior CT imaging or without additional consent for new CT imaging.
- Cases in which the Abbott Durata ICD lead was used, but the ICD or CRT-D pulse generator was manufactured by another company.
- Any other cases deemed inappropriate for inclusion in the study at the discretion of the principal investigator.
