This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial compares two ways of implanting a cardiac resynchronization therapy (CRT) device—a type of pacemaker that helps a weakened heart pump more effectively. One approach uses standard surgical techniques, while the other uses advanced MRI heart imaging to guide exactly where the device leads are placed. The goal is to see whether the imaging-guided approach helps more patients experience meaningful improvement in their heart function.
Not all patients respond equally well to CRT devices, even when they meet the medical criteria for implant. Researchers believe that using detailed heart imaging during the procedure could help doctors place the device leads in the most effective locations, potentially improving outcomes for more patients.

If you join this trial, you will be randomly assigned to receive either standard CRT device implant surgery or the same surgery using advanced MRI imaging to guide placement. You'll have study visits at the time of implant, before you leave the hospital, at 6 weeks, and at 6 months. At these visits, you'll receive heart imaging tests (like ultrasounds) to measure whether your heart function has improved. The entire trial lasts 6 months from implant to final assessment.
