Technologist Track Session 04: Nonischemic Cardiomyopathy (2018)-The non ischemic dilated heart

Video Transcription

Video Summary

The speaker introduces dilated cardiomyopathy (DCM) and its classification, then focuses on the role of cardiac MRI (CMR) in diagnosis and risk stratification. They explain how CMR assesses ventricular size and function and helps distinguish ischemic from non-ischemic injury using late gadolinium enhancement (LGE) and T1 mapping. The main clinical value is identifying myocardial scar, which strongly predicts higher risk of arrhythmias, ICD therapies, and worse prognosis. Several studies are cited showing LGE’s association with adverse outcomes in DCM, and newer data suggest fibrosis patterns may further refine patient management and guide decisions about ICD implantation.
