Summary

This trialwill compare two treatments for heart failure with RBBB to see which one works best.

Who is the study for?
This trial is for heart failure patients with right bundle branch block who meet specific criteria: they have certain levels of heart function and symptoms, are at least 18 years old, and follow optimal medical therapy. It's not for those with left bundle branch block, other ECG issues, or a life expectancy under one year.
What is being tested?
The study compares two types of pacemaker implantations in heart failure patients: His-bundle pacing (His-CRT) versus traditional cardiac resynchronization therapy (BIV-CRT). The goal is to see which method works better for correcting the heartbeat.
What are the potential side effects?
While the description doesn't list side effects explicitly, typical risks may include infection at the implant site, bleeding or bruising, lead displacement requiring repositioning, and rarely device malfunction.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Change in Left Ventricular Ejection Fraction at 6 months with His-CRT vs. BIV-CRT, in heart failure patients with Right bundle branch block (RBBB)
Secondary study objectives
Assess the mechanism of benefit with His-CRT vs. BIV-CRT by evaluating changes in ECG biomarkers
Assess the mechanism of benefit with His-CRT vs. BIV-CRT by evaluating changes in NT-proBNP
Assess the mechanism of benefit with His-CRT vs. BIV-CRT by evaluating changes in echocardiographic left ventricular end-diastolic volume (LVEDV)
+1 more
Other study objectives
Ascertain the mechanism of benefit on ventricular depolarization (QRS duration) over time, at 6 months, 12 months, and 24 months.
Heart failure (HF) or death events

Trial Design

2Treatment groups
Active Control
Group I: BIV-CRT implantationActive Control1 Intervention
BIV-CRT implantation includes implantation of three leads, an endocardial right atrial lead, an endocardial right ventricular lead, and an epicardial left ventricular lead implanted in a branch of the coronary sinus.
Group II: His-CRT implantationActive Control1 Intervention
His-CRT implantation includes implantation of three leads, an endocardial right atrial lead, an endocardial right ventricular lead, and an endocardial His-bundle pacing leads directly pacing the intrinsic conduction system.
