Trial summary
Study objective is to assess whether stimulation of the conduction system reduces cardiac decompensation events in patient follow-up, and how applicable this is in clinical practice and also to determine the impact of the studied interventions in terms of quality of life and cost-effectiveness for the treatment of… Read more about this study

About this study
Official title: RandomIsed sTudy of Physiologic cArdiac stimuLation in patIents With Atrio-ventricular Conduction Disease: the ITALIA Study
Study objective is to assess whether stimulation of the conduction system reduces cardiac decompensation events in patient follow-up, and how applicable this is in clinical practice and also to determine the impact of the studied interventions in terms of quality of life and cost-effectiveness for the treatment of patients with atrioventricular block. 1260 adult patients who are candidates for pacemaker implantation for the treatment of atrioventricular conduction disease will be randomised to stimulation of the conduction system or to the conventional stimulation.
- Conditions
- Atrioventricular Block
- Being tested
- Conduction System Pacing (CSP), Right Ventricular (RV) Pacing
- Medical subject headings
- Atrioventricular Block
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Conduction System Pacing (CSP)Procedure or surgery
CSP occurs at the left endocardic surface of the interventricular septum hence specifically designed delivery catheters are used to advance the ventricular lead across the septum until its left-sided edge, where the Left Bundle is located. To determine whether CSP has been achieved, a standard 12-lead electrocardiogram (ECG) is continuously recorded.
Right Ventricular (RV) PacingProcedure or surgery
RV pacing delivered either at the RV apex or RV septum. RV pacing is delivered by single chamber or dual chamber pacemakers depending on patients' rhythm (sinus or AT/AF) according to well-established clinical practice as described in the EHRA recommendtions
| Study group | Role | What they receive |
|---|---|---|
| Conduction System Pacing (CSP) | Experimental | CSP occurs at the left endocardic surface of the interventricular septum hence specifically designed delivery catheters are used to advance the ventricular lead across the septum until its left-sided edge, where the Left Bundle is located.

| Conventional System Pacing/Right Ventricular (RV) Pacing | Active comparator | RV pacing delivered either at the RV apex or RV septum. RV pacing is delivered by single chamber or dual chamber pacemakers depending on patients' rhythm (sinus or AT/AF) according to well-established clinical practice as described in the EHRA recommendtions Receives: Procedure: Right Ventricular (RV) Pacing |

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 5 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 27 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 14 sites in Italy. 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 Mauro Biffi, MD (+390512149034, mauro.biffi@aosp.bo.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Heart failure (time frame: 36 months after the PM implant). 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 27 May 2026.
