NCT ID: NCT06241651 Recruiting - Heart Failure Clinical Trials

CSP Versus BiVP for Heart Failure Patients With RVP Upgraded to Cardiac Resynchronization Therapy

CSP-UPGRADE
Start date: January 1, 2024
Phase: N/A
Study type: Interventional

The present study is a prospective, multicenter, non-inferiority, randomized controlled trail. It aims to investigate whether the efficacy of conduction system pacing (CSP) is non-inferior to biventricular pacing (BiVP) in patients with heart failure and right ventricular pacing (RVP) requiring upgrading to cardiac resynchronization therapy (CRT).

Long-term Outcomes of Conduction System Pacing: a National Multicenter Observational Study - NORMAND'HIS / STIMU'HIS

STIMU'HIS
Start date: March 1, 2023
Phase:
Study type: Observational [Patient Registry]

This prospective multicenter registry will evaluate the long-term electrical, echocardiographic, and clinical outcomes of conduction system pacing (CSP). There is currently limited data in the literature regarding the long-term results and benefits of CSP. The long-term maintenance of conduction system (His bundle or Left Bundle Branch) capture and physiological ventricular activation is an essential prerequisite for the expected benefits of this technique. There is currently no prospective study evaluating the preservation of CSP during long-term follow-up. The design of the present study will allow reliable evaluation of CSP maintenance at 2 years follow-up. The prospective collection of electrical data (pacing thresholds, impedance, R wave sensing) during pacemaker follow-up visits will confirm thresholds stability over the long term. The incidence of atrial fibrillation episodes will also be precisely evaluated and will provide new information. Although pathophysiological studies have demonstrated less impairment of left atrial function with conduction system pacing, there is currently no data on the incidence of atrial fibrillation in patients implanted with a CSP pacemaker. Echocardiographic data will be prospectively collected in order to analyse the evolution of left ventricular ejection fraction (LVEF) after CSP. This systematic follow-up is rarely found in CSP studies, often retrospective, with significant missing echocardiographic data. The hypothesis is that patients benefiting from CSP will not develop the deleterious effects demonstrated with conventional right ventricular pacing, such as left ventricular dilation and LVEF impairment. Inter- and intraventricular asynchrony criteria will also be systematically evaluated during follow-up echocardiography.Finally, this prospective cohort will also systematically collect clinical follow-up data (hospitalizations for heart failure and NYHA stage).

Conduction System Pacing Versus Biventricular Resynchronization in Patients With Chronic Heart Failure

PhysioSync-HF
Start date: November 7, 2022
Phase: Phase 3
Study type: Interventional

The purpose of this study is to evaluate the effect of conduction system pacing versus biventricular pacing on death, worsening heart failure, and left ventricular ejection fraction in patients with chronic heart failure with reduced ejection fraction and left bundle branch block.

Physiological Pacing for AV Block to Prevent Pacemaker-induced Cardiomyopathy

PHYSPAVB
Start date: February 1, 2022
Phase: N/A
Study type: Interventional

The implantation of a pacemaker and conventional cardiac pacing from the right ventricle (apex or septum) is an effective and safe therapy for the treatment of patients with atrioventricular block and bradycardia.

Conduction System Pacing vs Biventricular Resynchronization Therapy in Systolic Dysfunction and Wide QRS: CONSYST-CRT.

CONSYST-CRT
Start date: January 17, 2022
Phase: N/A
Study type: Interventional

Conduction system pacing vs biventricular resynchronization therapy in systolic dysfunction and wide QRS (CONSYST-CRT randomized clinical trial) is a non-inferiority trial that aims to study the composite endpoint consisting of all-cause mortality, cardiac transplant, heart failure hospitalizations, and left ventricular ejection fraction (LVEF) improvement <5 points.

LVSP vs RVP in Patients With AV Conduction Disorders

LEAP
Start date: May 1, 2021
Phase: N/A
Study type: Interventional

Rationale: Permanent cardiac pacing is the only available therapy in patients with atrioventricular (AV) conduction disorders and can be life-saving. Right ventricular pacing (RVP), the routine clinical practice for decades in these patients, is non-physiologic, leads to dyssynchronous electrical and mechanical activation of the ventricles, and may cause pacing-induced cardiomyopathy and heart failure. Left ventricular septal pacing (LVSP) is an emerging form of physiologic pacing that can possibly overcome the adverse effects of RVP. Study design and hypotheses: The LEAP trial is a multi-center investigator-initiated, prospective, randomized controlled, open label, blinded endpoint evaluation (PROBE) study that compares LVSP with conventional RVP. A total of four hundred seventy patients with a class I or IIa indication for pacemaker implantation due to AV conduction disorders and an expected ventricular pacing percentage >20% will be randomized 1:1 to LVSP or RVP. The primary endpoint is a composite endpoint of all-cause mortality, hospitalization for heart failure and a more than 10% decrease in left ventricular ejection fraction (LVEF) in absolute terms leading to a LVEF below 50% at one year follow-up. LVSP is anticipated to result in improved outcomes. Secondary objectives are to evaluate whether LVSP is cost-effective and associated with an improved quality of life (QOL) as compared to RVP. Quality of life is expected to improve with LVSP and reduced healthcare resource utilizations are expected to ensure lower costs in the LVSP group during follow-up, despite initial higher costs of the implantation. Study design: Multi-center investigator-initiated, prospective, randomized controlled, open label, blinded endpoint evaluation (PROBE) study. Study population: Adult patients with a bradycardia-pacing indication because of AV conduction disorders with an expected ventricular pacing percentage of ≥ 20% and a left ventricular ejection fraction (LVEF) > 35%. Four hundred seventy patients will be randomized 1:1 to LVSP or RVP. Intervention: LVSP vs RVP. Main study parameters/endpoints: The primary endpoint is a composite of all-cause mortality, hospitalization for heart failure, and a more than 10% decrease in left ventricular ejection fraction (LVEF) in absolute terms leading to a LVEF below 50%, which as a binary combined endpoint will be determined at one year follow-up. Secondary endpoints are: - Time to first occurrence of all cause mortality or hospitalization for heart failure. - Time to first occurrence of all cause mortality. - Time to first occurrence of hospitalization for heart failure. - Time to first occurrence of atrial fibrillation (AF) de novo. - The echocardiographic changes in LVEF at one year. - The echocardiographic changes in diastolic (dys-)function at one year. - The occurrence of pacemaker related complications. - Quality of life (QOL), cost-effectiveness analyses (CEA) and budget impact analysis (BIA). The secondary endpoints (other than echocardiographic LVEF change) will be determined at the end of the follow-up period, when the last included patient has reached one year follow-up. The individual follow-up time for patients at this time point will vary with a minimum of one year.
