Who may be able to join

  • Adult patients aged more than 18 years old
  • Patients diagnosed with heart failure (LVEF<50%) and have received optimal medical therapy for at least 3 months
  • Patients with permanent atrial fibrillation (QRS duration <130ms) which need ventricular pacing, including:
  • LVEF<50%, NYHA II-IV, drug-refractory atrial fibrillation with the fast ventricular rate, planned atrioventricular nodal ablation due to 1). anticipated low success rate of atrial fibrillation catheter ablation or 2). patients refused to receive catheter ablation or 3). refused to receive another catheter ablation after a previous history of failed procedures
  • LVEF<50%, NYHA II-IV, atrial fibrillation with slow ventricular rate, anticipated ventricular pacing burden ≥ 40%
  • Written informed consent was provided

Who cannot join

  • expected survival time is less than 12 months
  • Prior history of mechanical tricuspid valve replacement and/or congenital heart disease (including dextrocardia, transposition of the great arteries, single left persistent left superior vena cava, etc.)
  • Plan for PCI or CABG due to unstable angina or myocardial infarction in 3 months
  • Surgery is required within 1 year due to severe structural heart disease
  • Pregnancy, planned pregnancy or heart transplant
  • Prior history of HCM and/or ventricular septal defect repair, who are unlikely to achieve successful LBBAP procedure.
  • Failure of lead placement due to abnormal anatomy of the coronary sinus or enlarged right atrium, which makes it unable to switch from one pacing modality to another

About this study

Official title: Clinical Efficacy of Left Bundle Branch Area Pacing for Patients With Permanent Atrial Fibrillation and Heart Failure :A Multi-center Randomized Controlled Trial

This is a multicenter, randomized controlled study. This study aims to compare the clinical efficacy of LBBAP with traditional biventricular pacing in patients with permanent atrial fibrillation and heart Failure

Read the detailed description

LBBAP-AFHF is a prospective, multicenter, randomized controlled trial that is designed to determine whether left bundle branch area pacing (LBBAP) may show superiority of improved LV function as compared with traditional biventricular pacing (BiVP) in patients with permanent atrial fibrillation and heart failure (LVEF<50%) who receive atrioventricular nodal ablation due to fast ventricular rate or require high percentage of ventricular pacing due to slow ventricular rate. The primary endpoint of this trial is the change in the LVEF at 6 months after device implantation from baseline. A CRT-P/D device would be implanted and LBBAP lead would be connected to the RA port and LV lead to the LV port. Patients who receive successful LBBAP and BiVP simultaneously during the procedure would be 1:1 randomized to LBBAP or BiVP group after the procedure by device programming. Patients will be followed at 3 and 6 months post-discharge for LVEF and other echographic parameters (including LVESV, response rate), and rehospitalization for heart failure or all-cause death.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Left bundle branch area pacingDevice

    Left bundle branch area pacing is a novel physiological pacing modality and is reported to be feasible and safe in patients with heart failure and left bundle branch block.

  • Biventricular pacingDevice

    Biventricular pacing is a widely-established modality to treat heart failure in patients with heart failure

Study groups in NCT05549544
Study groupRoleWhat they receive
LBBAP groupExperimentalDevice: Left bundle branch area pacing(LBBAP) LBBAP is a novel physiological pacing form for ventricular pacing. In patients who received LBBAP, the pacing lead will be placed at the left bundle branch area to achieve a narrow-paced QRS duration.
Receives: Device: Left bundle branch area pacing
BiVP groupActive comparatorDevice: Biventricular pacing (BiVP) Biventricular pacing is the traditional pacing modality for patients with heart failure. For BiVP, one pacing lead was placed in the coronary sinus, named LV lead, and another lead was placed in the right ventricule.
Receives: Device: Biventricular pacing

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. ΔLVEF between baseline and six months post-discharge

    ΔLVEF:change in LVEF between baseline and six months after procedure

    Measured: Six months after device implantation

Secondary outcomes (9)
  1. The immediate success rate of the LBBAP procedure

    Successful LBBAP procedure is identified according to ECG and intracardiac ECG electrogram (IEGM) during the procedure. All LBBAP procedures will be categorized as selective left bundle branch pacing (S-LBBP), non-selective left bundle branch pacing(NS-LBBP), or left ventricular septal pacing (LVSP).

    Measured: 1 weeks

  2. The rate of procedure and Device related complications

    Procedure complications include pneumothorax, hemothorax, and air embolism. Device related complications include lead and pocket complications

    Measured: 6 months

  3. ΔLVEDD between baseline and six months post-discharge

    ΔLVEDD:change in LVEDD between baseline and six months after procedure between two groups

    Measured: 6 months

  4. ΔLVEDV between baseline and six months post-discharge

    ΔLVEDV:change in LVEDV between baseline and six months after procedure between two groups

    Measured: 6 months

  5. The echocardiographic response rate of LVEF increase ≥5%

    the percentage of patients with change of LVEF ≥5% at 6 month from baseline

    Measured: 6 months

  6. The changes of NT-proBNP betwen baseline and 6 months post-discharge

    The changes of NT-proBNP betwen baseline and 6 months post-discharge

    Measured: 6 months

  7. Composite incidence rate of all-cause mortality and/or hospitalization for heart failure

    All-cause death: including cardiovascular and non-cardiovascular deaths. Hospitalization for heart failure: an unplanned outpatient or emergency department visit or inpatient hospitalization in which the patient presented with signs and symptoms consistent with heart failure and required medication therapy.

    Measured: 6 months

  8. The echocardiographic response rate of LVEF increase ≥15%

    an increase in LVESV ≥15% during follow-up at 6 month compared with baseline

    Measured: 6 months

  9. The rate of ΔLVESV ≥15% between baseline and six months post-discharge

    the percentage of patients with change of ΔLVESV ≥15% at 6 month from baseline

    Measured: 6 months

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 10 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Haojie Zhu, M.D (+8613167310573, 13167310573@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

ΔLVEF between baseline and six months post-discharge (time frame: Six months after device implantation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jan 2024; AzTrials last refreshed its copy on 7 Nov 2026.
