Improving Pacing for Heart Failure with Bundle Branch Block

His-Bundle Corrective Pacing in Heart Failure

NIH-funded research University of Rochester · NIH-11129774

This research compares a new type of heart pacing called His-bundle corrective pacing with standard treatment for people living with heart failure and a specific electrical issue called right bundle branch block.

What this research studies

For individuals with heart failure and a specific heart rhythm problem called right bundle branch block, standard cardiac resynchronization therapy (BIV-CRT) may not be as effective. This project explores a newer approach, His-bundle corrective pacing (His-CRT), which targets the heart's natural electrical system more directly. We are conducting a clinical trial to see if His-CRT can improve heart function better than BIV-CRT in these patients. The goal is to understand how His-CRT works and if it leads to better outcomes for heart failure patients with this particular condition.

Who could benefit from this research

Good fit: Ideal candidates are individuals with heart failure, severely reduced left ventricular function, a wide QRS on their ECG, and a right bundle branch block ECG pattern.

Not a fit: Patients without heart failure, or those with heart failure but without a right bundle branch block, would likely not benefit from this specific pacing approach.

Why it matters

Potential benefit: If successful, this new pacing method could offer a more effective treatment option for heart failure patients who currently do not respond well to standard therapy due to right bundle branch block.

How similar studies have performed: His-bundle pacing is an emerging technology, and while some preliminary data exist, this randomized trial aims to provide more definitive evidence on its efficacy compared to established methods.
