58 year-old man with a history of diabetes and hypertension and recurrent syncope/palpitations. MRI ordered to assess for hypertrophic cardiomyopathy. Left VentricleThe left ventricle is normal in size with hyperdynamic function. The overall LV ejection fraction is 68%, the LV end diastolic volume index is 72 ml/m2 (normal range: 74+/-15), the LVEDV is 179 ml (normal range 142+/-34), the LV end systolic volume index is 23 ml/m2 (normal range 25+/-9), the LVESV is 57 ml (normal range 47+/-19), the LV mass index is 76 g/m2 (normal range 85+/-15), and the LV mass is 189 g (normal range 164+/-36). Maximum thickness of the myocardial wall on short-axis views 13 mm. There are no regional wall motion abnormalities present. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process. Myocardial T1 is 943 -1060 ms (normal range).Left AtriumThe left atrium is mild-moderately dilated. Right VentricleThe right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 65%, the RV end diastolic volume index is 76 ml/m2 (normal range 82+/-16), the RVEDV is 190 ml (normal range 142+/-31), the RV end systolic volume index is 27 ml/m2 (normal range 31+/-9), and the RVESV is 67 ml (normal range 54+/-17). Right AtriumThe right atrium is normal in size.Aortic ValveThe aortic valve opens widely and there is no significant aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is no significant mitral regurgitation.Pulmonic ValveThe pulmonic valve opens widely. There is no significant pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is no significant tricuspid regurgitation.AortaThere is a left sided aortic arch with a normal brachiocephalic branching pattern. The aortic root is normal in size.Pulmonary VeinsAll four pulmonary veins drain normally into the left atrium.Pulmonary ArteryThe main pulmonary artery is normal in size (26 mm)Venous AnatomyThe SVC and IVC drain normally into the right atrium.PericardiumThere is no obvious pericardial disease.Extracardiac FindingsThis study is not designed for the specific evaluation of extra-cardiac findings; therefore, the differentiation between artifacts and real extracardiac pathology may be difficult. If clinically indicated, a separate dedicated evaluation should be considered.
1. The left ventricle is normal in size with hyperdynamic function. The overall LV ejection fraction is 68%. Maximum thickness of the myocardial wall on short-axis views 13 mm2. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process.3. The right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 65%.
