48 year old woman with recent URI and elevated troponins without significant coronary disease, referred for cardiac MR to evaluate for possible myocarditis. Left VentricleThe left ventricle is normal in size with hyperdynamic systolic function. The overall LV ejection fraction is 69%, the LV end diastolic volume index is 81 ml/m2 (normal range: 65+/-11), the LVEDV is 172 ml (normal range 109+/-23), the LV end systolic volume index is 25 ml/m2 (normal range 18+/-5), the LVESV is 53 ml (normal range 31+/-10), the LV mass index is 70 g/m2 (normal range 67+/-11), and the LV mass is 149 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. Her myocardial T2-times are within normal limits, as was her global relative enhancement ratio.The native T1 myocardial relaxation time is mildly elevated, with an overall ECV of 36% which is also mildly elevated. This suggest diffuse mild underlying interstitial fibrosis. There is no myocardial iron overload. Left AtriumThe left atrium is mildly dilated. Right VentricleThe right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 51%, the RV end diastolic volume index is 76 ml/m2 (normal range 69+/-14), the RVEDV is 123 ml (normal range 110+/-24), the RV end systolic volume index is 37 ml/m2 (normal range 22+/-8), and the RVESV is 79 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 mild mitral regurgitation which is eccentric. There is mild thickening of the leaflet tips.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 a small pericardial effusion.Extracardiac FindingsThere is hilar lymphadenopathy. This 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 size left ventricle with hyperdynamic systolic function (EF 69%).2. No There is no late gadolinium enhancement to suggest the presence of an underlying focal/ replacement fibrosing, infiltrative, or inflammatory process. The native T1 myocardial relaxation time and extra-cellular volume fraction (ECV) are both mildly elevated suggesting the presence of mild diffuse interstitial fibrosis. 3. Normal size right ventricle with normal systolic function (EF 51%).4. Mild eccentric mitral regurgitation. 5. Small pericardial effusion. 6. See extra-cardiac findings. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
