Technologist Track Session 04: Nonischemic Cardiomyopathy (2018)-Hypertrophic cardiomyopathy

Video Transcription

Video Summary

The speaker reviews hypertrophic cardiomyopathy (HCM) and the role of cardiac MRI (CMR), especially gadolinium-based imaging. HCM is a common genetic heart disease with diverse morphologies, increased risk of sudden death, and myocardial fibrosis. CMR is highlighted as superior for detecting atypical hypertrophy, assessing left ventricular mass, function, and especially fibrosis through late gadolinium enhancement (LGE) and T1 mapping. LGE presence and extent predict worse outcomes, including sudden cardiac death. The talk concludes with an update on the NIH-supported HCMR study, which is following 2,773 patients to improve risk prediction using imaging, biomarkers, and genetics.
