Technologist Track Session 3: How I Do It: Patients with Cardiomyopathies-Hypertrophic Cardiomyopathy

Video Transcription

Video Summary

The talk reviewed practical cardiac MRI imaging of hypertrophic cardiomyopathy (HCM) at OSU. HCM is a genetic disorder causing unexplained left ventricular hypertrophy, with varied patterns and important complications like LVOT obstruction, mitral regurgitation, ischemia, arrhythmias, and sudden cardiac death. The speaker emphasized MRI sequences such as cine imaging, phase contrast flow, and late gadolinium enhancement (LGE), plus optional T1/T2 mapping and stress perfusion. MRI helps diagnose atypical HCM, quantify obstruction and regurgitation, detect fibrosis, and improve risk stratification, especially because greater LGE predicts worse outcomes and guides ICD decisions.
