Summary
This summary is machine-generated.

A simplified 9-partition method for Left bundle branch area pacing (LBBaP) significantly reduces procedure and fluoroscopy times. This technique offers a faster, cost-effective alternative to conventional LBBaP without compromising long-term pacing outcomes.

Area of Science:

  • Cardiology
  • Medical Devices
  • Electrophysiology

Background:

  • Left bundle branch area pacing (LBBaP) is a physiological pacing method.
  • Conventional LBBaP often requires complex procedures and expensive equipment.

Purpose of the Study:

  • To evaluate a simplified
  • 9-partition method
  • for performing LBBaP.
  • To compare the efficacy and efficiency of the simplified method versus conventional LBBaP.

Main Methods:

  • A
  • 9-partition method
  • was developed using a 3x3 grid on a right anterior oblique fluoroscopic view.
  • 51 patients were allocated to either conventional LBBaP (c-LBBaP) or simplified LBBaP (s-LBBaP).

Main Results:

  • The simplified LBBaP group showed significantly shorter total procedure duration (70.68 ± 13.26 min vs 91.57 ± 19.51 min) and fluoroscopy time (10.54 ± 3.13 min vs 16.52 ± 5.34 min).
  • Time to lead implantation was also significantly reduced in the s-LBBaP group.
  • No significant differences in pacing parameters were observed between groups after 3 months.

Conclusions:

  • The simplified
  • 9-partition method
  • is a faster and potentially more cost-effective approach for LBBaP.
  • This method eliminates the need for expensive electrophysiological recording systems.
