Figure S2E-60-year-old woman with symmetric hypertrophic cardiomyopathy who underwent cardiac MRI before surgical intervention for mitral valve regurgitation and left ventricle (LV) outflow tract obliteration. Cine two-chamber long-axis loop shows moderate to severe mitral valve insufficiency and regurgitant jet (signal void). Note global hyperkinesia of hypertrophic LV (ejection fraction: 85%).

Figure S3G-44-year-old man with asymmetric hypertrophic cardiomyopathy and chest pain on minor exertion. Cine short-axis loop shows hypokinesia of interventricular septum and of midbasal anterior left ventricle (LV) wall, where hypertrophy is located. Note regular contraction and systolic thickening of remaining LV walls (ejection fraction: 70%).

Figures S5E and S5F-51-year-old woman who was admitted to coronary unit for repeated episodes of syncope of unknown origin. Final diagnosis was arrhythmogenic right ventricular cardiomyopathy. E and F, Cine short-axis (E) and two-chamber long-axis (F) loops show marked hypokinesia of right ventricle (ejection fraction, 15%) with diffuse and gross end-systolic bulging in right ventricle outflow tract and free wall. Note regular systolic function of left ventricle (ejection fraction: 60%).
