43 year old female with history of breast cancer, LV dysfunction on prechemotherapy echo (mildly reduced LV systolic function noted on echo, but MRI 2 days later showed normal function). Referred for cardiac MRI to reassess LV function. Left VentricleThe left ventricle is normal in size with mildly reduced systolic function. The overall LV ejection fraction is 49%. The LVEDV is 147 ml (normal range 109+/-23), LV end diastolic volume index is 78 ml/m2 (normal range: 65+/-11), LVESV is 76 ml (normal range 31+/-10), and LV end systolic volume index is 40 ml/m2 (normal range 18+/-5). The LV mass is 72 g (normal range 114+/-24) and the LV mass index is 39 g/m2 (normal range 67+/-11). There are no regional wall motion abnormalities present. Persistent indeterminate small focus of late gadolinium enhancement at the inferior septal wall of the left ventricle, at the insertion site of the right ventricle. There are no findings to suggest the presence of a diffuse underlying fibrosing, infiltrative, or inflammatory process.The native T1 myocardial relaxation time is 982 ms in the lateral LV wall and 1017 ms in the septum. These values are not suggestive of underlying diffuse fibrosis or infiltration.There is no myocardial iron overload. There is no LV thrombus. Left AtriumThe left atrium is normal in size.Right VentricleThe right ventricle is normal in size with mildly reduced systolic function. The overall RV ejection fraction is 46%, the RVEDV is 137 ml (normal range 110+/-24), the RV end diastolic volume index is 72 ml/m2 (normal range 69+/-14), the RVESV is 74 ml (normal range 35+/-13), and the RV end systolic volume index is 40 ml/m2 (normal range 22+/-8).Right AtriumThe right atrium is normal in size. Aortic ValveThe aortic valve is trileaflet, 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. 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 normal in size with mildly reduced systolic function. The overall LV ejection fraction is 49%. 2.The right ventricle is normal in size with mildly reduced systolic function. The overall RV ejection fraction is 46%3.There is no late gadolinium enhancement to suggest the presence of a diffuse underlying fibrosing, infiltrative, or inflammatory process.4.The native T1 myocardial relaxation times are within normal limits, suggesting the absence of an underlying fibrosing, infiltrative, or inflammatory process.
