Technologist Track Session 4: Heart Failure I (2019)-Hypertrophic cardiomyopathy

Video Transcription

Video Summary

The speaker explains the role of cardiac MRI (CMR) in evaluating hypertrophic cardiomyopathy, especially when echocardiography is limited or when apical hypertrophy, aneurysm, thrombus, or LV outflow obstruction is suspected. CMR helps assess anatomy, function, fibrosis, and alternative causes of hypertrophy such as amyloidosis, Fabry disease, and sarcoidosis. Key sequences include cine SSFP, LGE, velocity encoding, and tagging. Important reporting points are maximal wall thickness and LGE extent. LGE and morphology aid diagnosis and risk assessment, though LGE is not definitive for sudden cardiac death prediction.
