RandomIsed sTudy of Physiologic cArdiac stimuLation in patIents With Atrio-ventricular Conduction Disease

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 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.

Eligibility

Inclusion Criteria:

* Adult patients with AV block in either sinus rhythm (SR) or permanent atrial tachycardia/atrial fibrillation (AT/AF), or with slow AV conduction during AT/AF, or undergoing AV node ablation + ventricular stimulation
* male and female
* acquired informed consent

Exclusion Criteria:

* Class I indication to Implantable Cardioverter Defibrillator (ICD) or to Cardiac Resynchronization Therapy (CRT)
* Ejection Fraction \< 35%
* Life expectancy \< 2 years
* Participation in another clinical trial which might impact on the study outcome
* Pregnancy, except as "In the event of an ongoing pregnancy, the doctor and patient will jointly assess, on a case-by-case basis and in the best interests of the patient, whether to propose participation in the study (random assignment to one of the two stimulation techniques) or to proceed as per clinical practice (assignment to one of the two stimulation techniques by the doctor). A screening log file of all eligible patients will be recorded, detailing the reason/s for non-randomization."
