Safety and performance of the Medtronic 3830 lead in His-bundle and Left bundle branch area pacing: A single-center experience

Area of Science:

• Cardiology
• Electrophysiology
• Medical Devices

Background:

• Conduction system pacing (CSP) offers physiological advantages over traditional right ventricular pacing (RVP).
• His Bundle Pacing (HBP) and Left Bundle Branch Area Pacing (LBAP) are emerging CSP techniques.
• Evaluation of Medtronic SelectSecure 3830 leads in CSP is crucial.

Purpose of the Study:

• To assess the safety, feasibility, and performance of HBP and LBAP.
• To compare outcomes between HBP and LBAP using specific lead models.
• To analyze pacing thresholds, device longevity, and complication rates.

Main Methods:

• Single-center retrospective analysis of 490 patients.
• Inclusion of patients undergoing HBP or LBAP.
• Follow-up averaging 28 months for HBP and 14 months for LBAP.

Main Results:

• Implantation success rates: 85% for HBP, 97.4% for LBAP.
• LBAP exhibited lower, more stable pacing thresholds and fewer revisions than HBP.
• Complications were minimal and comparable; LVEF remained stable.

Conclusions:

• HBP and LBAP are safe and feasible CSP methods with similar safety profiles.
• LBAP demonstrates potential advantages in pacing stability, revision rates, and device longevity.
• Further research is needed for optimal lead placement and long-term CSP outcomes.
