Trial summary

Multicenter randomized controlled trial which will include patients with left ventricular ejection fraction >50% requiring a first implant of a cardiac pacemaker with expected high pacing percentages. Patients will be randomized 1:1 to right ventricular apical pacing vs left septal or deep septal pacing. Read more about this study

About this study

Multicenter randomized controlled trial which will include patients with left ventricular ejection fraction >50% requiring a first implant of a cardiac pacemaker with expected high pacing percentages.

Patients will be randomized 1:1 to right ventricular apical pacing vs left septal or deep septal pacing. The primary endpoint will be pacing-induced cardiomyopathy during the first year of follow-up.

Being tested
Pacemaker implant

What participants receive

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

  • Pacemaker implantDevice

    All patients in the study will have a clear indication for a permanent pacemaker. The type of device (single or dual chamber) will be chosen as per clinical practice. The only difference between the two groups of the study will be the position of the ventricular lead.

Study groups in NCT06474819
Study groupRoleWhat they receive
deepExperimentalThe ventricular lead will be penetrated into the basal interventricular septum aiming at left septal pacing and, if not possible, at least deep septal pacing with a paced QRS duration <=140ms.
Receives: Device: Pacemaker implant
ApexActive comparatorThe ventricular lead will be placed in the right ventricular apex.
Receives: Device: Pacemaker implant

What is being measured

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

  1. Pacing-induced cardiomyopathy

    Decrease in the left ventricular ejection fraction (LVEF) by >10% as compared to the LVEF before pacemaker implant and final LVEF<45%.

    Measured: 12 months

Secondary outcomes (5)
  1. LVEF during follow-up

    To compare the mean or median (depending on distribution) LVEF before and one year after pacemaker implant in the two groups.

    Measured: 12 months

  2. Mitral and tricuspid regurgitation

    To compare the degree of mitral and tricuspid regurgitation before and one year after pacemaker implant in the two groups.

    Measured: 12 months

  3. New York Heart Association (NYHA) class

    To compare the NYHA class one year after pacemaker implant in the two groups.

    Measured: 12 months

  4. Brain Natriuretic Peptide levels

    To compare the N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels one year after pacemaker implant in the two groups.

    Measured: 12 months

  5. heart failure

    Comparison of heart failure (HF) events in the first year after pacemaker implant in the two groups. HF events will be: hospitalizations for heart failure, emergency department or day-hospital visits for heart failure, heart failure symptoms requiring the initiation of diuretic therapy.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Pacemaker implant in people with Complete Heart Block and Second Degree Atrioventricular Block Möbitz Type II, run by Institut d'Investigació Biomèdica de Bellvitge at 6 sites in Spain.

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 3 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 15 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Spain. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Andrea Di Marco, MD, PhD (+34932 60 75 00 ext. 8385, adimarco@bellvitgehospital.cat), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pacing-induced cardiomyopathy (time frame: 12 months). 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 15 Jul 2024.
