54 year old woman with AL amyloid who presents for cardiac MRI to evaluate for cardiac involvement. Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 61%, the LV end diastolic volume index is 64 ml/m2 (normal range: 65+/-11), the LVEDV is 133 ml (normal range 109+/-23), the LV end systolic volume index is 25 ml/m2 (normal range 18+/-5), the LVESV is 51 ml (normal range 31+/-10), the LV mass index is 53 g/m2 (normal range 67+/-11), and the LV mass is 110 g (normal range 114+/-24). There are no regional wall motion abnormalities present. Measured T1 value of myocardium 1150msLeft AtriumThe left atrium is mildly dilated. There is lipomatous hypertrophy of the interatrial septumRight VentricleThe right ventricle is normal in size and systolic function. The overall RV ejection fraction is 67%, the RV end diastolic volume index is 42 ml/m2 (normal range 69+/-14), the RVEDV is 124 ml (normal range 110+/-24), the RV end systolic volume index is 21 ml/m2 (normal range 22+/-8), and the RVESV is 43 ml (normal range 35+/-13). Right AtriumThe right atrium is mildly dilated. 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 trace pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is mild 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. Venous AnatomyThe SVC and IVC are normal in size and drain normally into the right atrium. PericardiumThere is a small pericardial effusion.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 normal systolic function[LVEF 61%]2. Measured T1 value of myocardium 1150ms3. The right ventricle is normal in size and systolic function [RVEF 67%]4. Mild biatrial enlargement5. Lipomatous hypertrophy of interatrial septumI personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
