This is a mechanistic clinical trial with randomization to guidance for the CRT procedure using cardiac magnetic resonance (CMR) and computed tomography angiography (CTA) versus a standard procedure.
At baseline, patients will have CMR, CTA, echocardiography, blood testing, and cardiopulmonary exercise testing. They will also complete a heart failure questionnaire. In patients randomized to CMR guidance for the CRT procedure, LV lead placement will be guided by the MRI information related to scar, activation and anatomy. Patients will have follow-up assessments at 6 and 12 months. There will also be clinical follow-up for survival free of appropriate ICD therapies over 3 years.
