The Valley Hospital is now open at 4 Valley Health Plaza in Paramus. (You may need to use 650 Winters Avenue for GPS.) All emergency care is now being provided at this location. Emergency care is no longer available at our Ridgewood campus.
His Bundle Corrective Pacing in Heart Failure (HIS-CRT)
Objective
The objective of this study is 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.
Study Arms
- Active Comparator: HIS-CRT implantation
- Active Comparator: BIV-CRT Implantation
Eligibility
- Age 18 years or older (no upper age limit)
- Optimal medical therapy for heart failure by current guidelines
- Class IIa or IIb guideline-based indication for CRT-D implant in RBBB patients, including one of the following:
- New York Heart Association (NYHA) class II HF symptoms, LVEF ≤ 30% and QRS≥ 150 ms (IIb); OR
- NYHA class III-IV a HF, LVEF ≤ 35%, and QRS duration ≥ 150 ms (IIa); OR
- NYHA class III-IV a HF, LVEF ≤ 35%, and QRS duration 120-149 ms (IIb)
