25 year old with history of chest pain and newly diagnosed left ventricular systolic dysfunction. Left VentricleSevere LV dilation when adjusted for body surface area (mildly dilated based on absolute volume) with mildly reduced systolic function. The overall LV ejection fraction is 51%, the LV end diastolic volume index is 109 ml/m2 (normal range: 65+/-11), the LVEDV is 166 ml (normal range 109+/-23), the LV end systolic volume index is 54 ml/m2 (normal range 18+/-5), the LVESV is 82 ml (normal range 31+/-10), the LV mass index is 59 g/m2 (normal range 67+/-11), and the LV mass is 90 g (normal range 114+/-24). The systolic dysfunction is global. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process.Left AtriumThe left atrium is mildly enlarged. 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 91 ml/m2 (normal range 69+/-14), the RVEDV is 139 ml (normal range 110+/-24), the RV end systolic volume index is 36 ml/m2 (normal range 22+/-8), and the RVESV is 55 ml (normal range 35+/-13). 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 with evidence of mitral valve prolapse and bileaflet billowing. Trace 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. Normal origin of the coronary arteries.Shunts No evidence of atrial septal defect or ventricular septal defect.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 trace 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. Severe LV dilation when adjusted for body surface area (mildly dilated based on absolute volume) with mildly reduced systolic function (LVEF 51%). No evidence of underlying myocardial fibrosis, infiltration, and inflammation.2. Normal RV size and systolic function (RVEF 60%).3. Mild left atrial dilation.4. Mitral valve prolapse with bileaflet billowing.5. No evidence of cardiac shunt. Normal coronary origins.
