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

Condition(s) studied

Investigational drug(s) / intervention(s)

Conduction System Pacing (CSP): 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) Pacing: 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 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

Primary outcome measure(s)

• Heart failure — 36 months after the PM implant
  composite endponit of: number of HF events, HF hospitalizations and HF non-pharmacological interventions
