21 year old woman with history of Lupus and tachycardia who presents for cardiac MRI to evaluate for LV function and structure and to rule out myocarditis Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 64%, the LV end diastolic volume index is 61 ml/m2 (normal range: 65+/-11), the LVEDV is 111 ml (normal range 109+/-23), the LV end systolic volume index is 22 ml/m2 (normal range 18+/-5), the LVESV is 40 ml (normal range 31+/-10), the LV mass index is 32 g/m2 (normal range 67+/-11), and the LV mass is 58 g (normal range 114+/-24). 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. Left AtriumThe left atrium is normal in sizeRight VentricleThe right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 61%, the RV end diastolic volume index is 66 ml/m2 (normal range 69+/-14), the RVEDV is 121 ml (normal range 110+/-24), the RV end systolic volume index is 26 ml/m2 (normal range 22+/-8), and the RVESV is 48 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 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 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. PericardiumThe pericardium along the basal anterior border of the heart has evidence of increased T2-signal, early gadolinium enhancement, and late gadolinium enhancement, which suggests the diagnosis of acute focal pericarditis.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 and systolic function (LVEF 64%) without evidence an underlying myocardial fibrosing, infiltrative, or inflammatory process. 2. Normal right ventricular size and systolic function (RVEF 61%).3. There is evidence of acute focal pericarditis along the basal anterior border of the heart.
