Study Details

Brief summary:

This study is evaluating how MRI after CRT can provide key insights regarding LV function, structure, and mechanics resulting from CRT in patients with or without LV scar and inform optimal pacing strategies. The expected accurate and reproducible response assessment with cardiac MRI has important implications for evaluating CRT outcomes in clinical trials, and the insights from the post-CRT MRI promise to improve implementation of CRT.
