34 year old man with non-ischemic cardiomyopathy and palpitations and wide-complex tachycardia. Left VentricleThe left ventricle is normal in size with mildly reduced systolic function. The overall LV ejection fraction is 50%, the LV end diastolic volume index is 103 ml/m2 (normal range: 74+/-15), the LVEDV is 223 ml (normal range 142+/-34), the LV end systolic volume index is 52 ml/m2 (normal range 25+/-9), the LVESV is 112 ml (normal range 47+/-19), the LV mass index is 66 g/m2 (normal range 85+/-15), and the LV mass is 142 g (normal range 164+/-36). 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. No evidence of myocardial iron overload.Left AtriumThe left atrium is mildly dilated. Right VentricleThe right ventricle is normal in size and systolic function. The overall RV ejection fraction is 52%, the RV end diastolic volume index is 115 ml/m2 (normal range 82+/-16), the RVEDV is 248 ml (normal range 142+/-31), the RV end systolic volume index is 55 ml/m2 (normal range 31+/-9), and the RVESV is 119 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 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 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. Normal LV size with mildly reduced systolic function (LVEF 50%) without evidence of underlying myocardial fibrosis, inflammation, or infiltration.2 Normal RV size and systolic function (RVEF 52%).3. Mild left atrial dilation.
