32 year old male with history of asymptomatic left ventricular dysfunction thought to be secondary to chemotherapy for Stage IV neuroblastoma at the age of 4 (treated with chemotherapy, radiation and BMT). Left VentricleThe left ventricle is normal in size with mildly reduced left ventricular systolic function. The overall LV ejection fraction is 51%, the LV end diastolic volume index is 63 ml/m2 (normal range: 74+/-15), the LVEDV is 107 ml (normal range 142+/-34), the LV end systolic volume index is 31 ml/m2 (normal range 25+/-9), the LVESV is 53 ml (normal range 47+/-19), the LV mass index is 34 g/m2 (normal range 85+/-15), and the LV mass is 58 g (normal range 164+/-36). The left ventricular dysfunction is global with regional variation. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process.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 60%, the RV end diastolic volume index is 62 ml/m2 (normal range 82+/-16), the RVEDV is 104 ml (normal range 142+/-31), the RV end systolic volume index is 24 ml/m2 (normal range 31+/-9), and the RVESV is 42 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 trace significant mitral regurgitation.Pulmonic ValveThe pulmonic valve opens widely. There is no significant pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is mild 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. Normal left ventricular size with mildly reduced systolic function (LVEF 51%). The systolic dysfunction is global and there is no evidence of late gadolinium enhancement to suggest scar or fibrosis. 2. Normal right ventricular size with normal systolic function (RVEF 60%).
