Clinical Trial Summary

The investigators aim to prospectively evaluate the efficacy and mechanism of benefit of His-bundle pacing enhanced cardiac resynchronization therapy (His-CRT) vs. cardiac resynchronization therapy (BIV-CRT) in patients with heart failure and right bundle branch block (RBBB).


Clinical Trial Description

In this prospective, randomized, multi-center clinical trial, the investigators aim to prospectively evaluate the efficacy and mechanism of benefit of His-bundle pacing enhanced cardiac resynchronization therapy (His-CRT) vs. cardiac resynchronization therapy (BIV-CRT) in patients with Right Bundle Branch Block (RBBB) Electrocardiogram (ECG) Pattern by assessing the improvement in left ventricular ejection fraction (LVEF) in the His-CRT vs. BIV-CRT arm at 6 months, and by evaluating changes in ECG biomarkers, NT-pro-brain natriuretic peptide (NT-proBNP) levels, and echocardiography biomarkers (left ventricular volumes, strain contractility, and dyssynchrony), as well as temporal changes in functional status and quality of life in the His-CRT vs. BIV-CRT arm at 6, 12, and 24 months. ;
