31 year old woman with history of Crohn's disease and palpitations with previous episodes of ventricular bigeminy and childhood non-sustained VT, referred for cardiac MRI to evaluate for scar. Left VentricleThe left ventricle is mildly dilated with normal systolic function. The overall LV ejection fraction is 56%, the LV end diastolic volume index is 92 ml/m2 (normal range: 65+/-11), the LVEDV is 160 ml (normal range 109+/-23), the LV end systolic volume index is 41 ml/m2 (normal range 18+/-5), the LVESV is 71 ml (normal range 31+/-10), the LV mass index is 37 g/m2 (normal range 67+/-11), and the LV mass is 63 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. The native T1 myocardial relaxation time is 1070ms which is borderline elevated.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 51%, the RV end diastolic volume index is 96 ml/m2 (normal range 69+/-14), the RVEDV is 167 ml (normal range 110+/-24), the RV end systolic volume index is 47 ml/m2 (normal range 22+/-8), and the RVESV is 82 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. PericardiumThere is trivial pericardial effusion without evidence of pericardial inflammation. 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 mildly dilated with normal systolic function (EF 56%). 2. The right ventricle is normal in size with normal systolic function (EF 51%). 3. There is no evidence of myocardial late gadolinium enhancement to suggest underlying infiltrative, inflammatory or major fibrotic process. 4. The native myocardial T1 relaxation time is borderline elevated, which could represent subtle interstitial myocardial fibrosis. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
