NCT05722379

Brief Summary

Although emerging evidence demonstrated that left bundle branch pacing (LBBP) is a promising alternative for patients with either a bradycardia or a heart failure pacing indication. However, a direct comparison of the safety, efficacy and LV systolic synchrony between LBBP and RVP regimens was rare. In this study, the investigators aim to conduct a comparison of the safety and effectiveness performance between these two pacing methods for patients with atrioventricular block (AVB). The investigators focused on AVB patients undergoing permanent pacemaker implantations from the 1st of January 2018 to the 18th of November 2021 at West China Hospital.

Outcome Measures

Primary Outcomes (3)

  • composed of all-cause mortality, lead failure and heart failure hospitalization (HFH) during the follow-ups

    composed of all-cause mortality, lead failure and heart failure hospitalization (HFH) during the follow-ups

    through study completion, an average of 2.45 year

  • Lead failure

    reintervention for increased pacing thresholds, lead dislocation or ventricular perforation after the initial implantation procedure

    through study completion, an average of 2.45 year

  • HFH

    HFH was defined as the admission to hospital for \>24 hours with worsening symptoms and signs of heart failure and requiring one or more intravenous diuretics or intravenous inotropic medications

    through study completion, an average of 2.45 year

Secondary Outcomes (3)

  • peri-procedure complication

    through study completion, an average of 2.45 year

  • cardiac death

    through study completion, an average of 2.45 year

  • recurrent unexplained syncope

    through study completion, an average of 2.45 year

Study Arms (1)

high-grade AVB patients undergoing permanent pacemaker implantations

Procedure: left bundle branch pacing (LBBP)Procedure: Right ventricular pacing (RVP)

Interventions

After recording the His potential, the 3830-69 lead (Medtronic Inc., Minneapolis, MN USA) was sent 1-2 cm forward and downward to find the insertion point of the right side of intra-ventricular septum combined with the pre-rotation impedance and ECG changes. Ultimately, the tip was perpendicularly straightforward posited against the septum to the left septal side .

Right ventricular pacing (RVP) is the standard treatment for patients with continuous ventricular pacing needs.
