Summary

This trial tests if placing a new electrode in a different part of the heart may improve heart function & reduce heart failure symptoms in patients who haven't improved after cardiac resynchronization therapy.

Who is the study for?
This trial is for veterans with heart failure who didn't get better after cardiac resynchronization therapy (CRT) at least a year ago. They should not have improved in symptoms, heart pumping function, or heart size reduction. It's not for those with weak immune systems, cancer patients on chemo, pregnant women, or anyone unable to follow the study plan.
What is being tested?
The study tests if placing a new pacing lead in a different part of the heart can help people whose hearts haven't responded to CRT. Participants will undergo an MRI and receive left bundle branch area pacing to see if it improves their heart function and reduces symptoms.
What are the potential side effects?
Possible side effects include discomfort from the new pacemaker placement procedure, risks associated with undergoing an MRI like claustrophobia or reactions to metal implants, and potential infection risk from the surgery.

Trial Design

2Treatment groups
Experimental Treatment
Group I: LBBAPExperimental Treatment1 Intervention
This arm will investigate improvement in cardiac function following placement of the LBBA pacing electrode in half the patients.
Group II: Cardiac MRI with devicesExperimental Treatment1 Intervention
This arm will investigate the feasibility of cardiac MRI to be used to measure cardiac function in patients with cardiac devices.
