38 year old male with non-ischemic cardiomyopathy referred for further evaluation with cardiac MRI. Left VentricleThe left ventricle is severely dilated with severely reduced systolic function. The LV is hyper-trabeculated. The overall LV ejection fraction is 19%, the LV end diastolic volume index is 141 ml/m2 (normal range: 74+/-15), the LVEDV is 283 ml (normal range 142+/-34), the LV end systolic volume index is 114 ml/m2 (normal range 25+/-9), the LVESV is 230 ml (normal range 47+/-19), the LV mass index is 35 g/m2 (normal range 85+/-15), and the LV mass is 71 g (normal range 164+/-36). There is global hypokinesis with regional variation. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process. There is no evidence of myocardial iron overload. No LV thrombus is noted. Left AtriumThe left atrium is severely dilated. Right VentricleThe right ventricle is normal in size and systolic function. The overall RV ejection fraction is 50%, the RV end diastolic volume index is 67 ml/m2 (normal range 82+/-16), the RVEDV is 135 ml (normal range 142+/-31), the RV end systolic volume index is 34 ml/m2 (normal range 31+/-9), and the RVESV is 68 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 mild 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.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 severely dilated with severely reduced systolic function (LVEF 19%). The LV is hyper-trabeculated. There is no evidence of underlying myocardial fibrosis, inflammation, or infiltration. 2. The right ventricle is normal in size and systolic function (RVEF 50%).3. Severe left atrial dilation. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
