Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Patients with heart failure and left bundle branch block benefit from Cardiac Resynchronization Therapy (CRT) that delivers pacing from right ventricle (RV) and left ventricle (LV) synchronously, resulting in electrical ventricular resynchrony followed by revere structural cardiac remodeling and thereby reduced heart failure symptoms, hospitalizations and death. It is not known if programming an individually optimized RV-LV pacing offset to maximize electrical resynchrony can improve benefit from CRT. The proposed study is a randomized controlled trial in patients undergoing implant of a CRT pacemaker/defibrillator device for clinical indications to evaluate benefit of RV-LV offset programming using electrocardiogram (ECG) vs. standard nominal CRT programming without RV-LV offset. Patients receiving CRT devices will be randomized to either (A) active intervention of programming RV-LV pacing offset to optimize ECG or to (B) active control of nominally programming CRT device without RV- LV offset. The patients will be followed to evaluate change in echocardiogram, quality of life, functional evaluation and a blood marker for heart failure.
