Summary
Probe-Left Bundle Branch Area Pacing (p-LBBAP) reduces procedure time and fluoroscopy exposure compared to conventional LBBAP. This novel technique offers a reliable physiological pacing approach without compromising lead performance or patient outcomes.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Left Bundle Branch Area Pacing (LBBAP) is an advanced physiological pacing method.
- The complexity of conventional LBBAP (c-LBBAP) hinders its widespread clinical adoption.
- A novel technique, probe-LBBAP (p-LBBAP), aims to simplify LBBAP implantation.
Purpose of the Study:
- To compare the clinical efficacy of p-LBBAP versus c-LBBAP.
- To evaluate procedural efficiency and lead performance in physiological cardiac pacing.
Main Methods:
- Retrospective analysis of 20 patients undergoing physiological pacing.
- Patients divided into p-LBBAP (n=10) and c-LBBAP (n=10) groups.
- Comparison of intraoperative times, lead parameters, QRS duration, and echocardiographic outcomes.
Main Results:
- p-LBBAP significantly reduced LBBAP lead implantation time and fluoroscopy time versus c-LBBAP.
- No significant differences in postoperative QRS duration, lead thresholds, or impedance between groups.
- Stable lead parameters and no increase in complications observed at 6-month follow-up.
Conclusions:
- The p-LBBAP technique is a reliable and efficient approach for physiological pacing.
- p-LBBAP shortens procedure duration and radiation exposure while maintaining pacing efficacy.
- This method demonstrates potential for broader clinical application of LBBAP.
