Summary
This study planned to test a new way to program cardiac resynchronization therapy (CRT) devices for heart failure patients who didn't get enough benefit from standard settings. Researchers would use ECG and cardiac MRI to find the best device settings and measure changes in heart function. However, the study was withdrawn before any participants were enrolled.

CRT device programming optimization
What this could lead to
If successful, this could lead to better ways to program CRT devices for heart failure patients who don't respond to standard settings.
What could go wrong
The study was withdrawn before enrolling any participants, so no results are available. It's unclear if the approach would work in practice.
