September 3, 2023 updated by: Peking Union Medical College Hospital

The Impact of Left Bundle Branch Area Pacing Versus Right Ventricular Pacing on the Incidence of New-onset Atrial Fibrillation in Patients With Atrioventricular Block: a Randomized Controlled Trial

This is a single-center, randomized controlled study. The aim of this study is to compare the impact of left bundle branch area pacing versus traditional right ventricular pacing on the incidence of atrial fibrillation in patients with atrioventricular block.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Adult patients aged 18-85;
  • AV block patients with ventricular pacing indications and the expected rate of ventricular pacing(VP)> 40%, including (a) third-degree AV block; (b) second degree AV block (type II); (c) intermittent advanced AV block with expected VP>40%; (d) symptomatic first degree AV block and PR interval on ECG > 300ms;
  • Signed informed consent;

Exclusion Criteria:

  • Baseline echocardiographic assessment of patients with impaired LV function (LVEF<50%);
  • Patients with the history of atrial fibrillation;
  • Having difficulties in follow-up: Those who cannot accept 2-year follow-up on time due to physical condition or other reasons;
  • Pacemaker replacement without new implanted ventricular electrodes;
  • Surgery is required within 1 year due to severe structural heart disease;
  • Patients with tricuspid mechanical valve replacement, or congenital heart disease (including transposition of the great arteries, or permanent left superior vena cava, etc);
  • AV block resulting from: (a) Hypertrophic cardiomyopathy(HCM), (b) ventricular septal defect repair, and those who are unlikely to achieve successful LBBAP procedure.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: left bundle branch area pacing
Procedure: left bundle branch area pacing
Left bundle branch area pacing(LBBAP) is a novel physiological pacing form for ventricular pacing. In patients received LBBAP, the pacing lead will be placed at left bundle branch area to achieve narrow paced QRS duration.
Active Comparator: right ventricular pacing
Procedure: right ventricular pacing
Right ventricular pacing is the traditional pacing modality for ventricular pacing. The pacing lead was placed in the apex or septum of right ventricle.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame

Time Frame: within two years after device implantation
within two years after device implantation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
