72 year old man with history of AL amyloidosis, referred for cardiac MRI to evaluate for cardiac involvement. Left VentricleThe left ventricle is normal in size with normal systolic function. There is moderate left ventricular hypertrophy. The overall LV ejection fraction is 63%, the LV end diastolic volume index is 81 ml/m2 (normal range: 74+/-15), the LVEDV is 162 ml (normal range 142+/-34), the LV end systolic volume index is 30 ml/m2 (normal range 25+/-9), the LVESV is 60 ml (normal range 47+/-19). There are no regional wall motion abnormalities present. Non-contrast T1 time of the IVS was 1017 msec which is not consistent with cardiac amyloid.Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 52%, the RV end diastolic volume index is 66 ml/m2 (normal range 82+/-16), the RVEDV is 137 ml (normal range 142+/-31), the RV end systolic volume index is 32 ml/m2 (normal range 31+/-9), and the RVESV is 66 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 trace 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.Venous AnatomyThe SVC and IVC are normal in size and 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 normal systolic function. The overall LV ejection fraction is 63%2. There is moderate left ventricular hypertrophy. 3. The T1 mapping demonstrates a T1 of the IVS of 1017 msec which is in the normal range.4. The right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 52%I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
