35 year old woman with significant family history of non-ischemic cardiomyopathy and VT, referred for cardiac MRI to evaluate for structural heart disease. Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 57%, the LV end diastolic volume index is 74 ml/m2 (normal range: 65+/-11), the LVEDV is 177 ml (normal range 109+/-23), the LV end systolic volume index is 32 ml/m2 (normal range 18+/-5), the LVESV is 75 ml (normal range 31+/-10), the LV mass index is 41 g/m2 (normal range 67+/-11), and the LV mass is 97 g (normal range 114+/-24). There are no regional wall motion abnormalities present. There is no evidence of myocardial edema. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process.The a borderline increase in native T1 myocardial relaxation time in the basal inferior and basal septum (1090-1100ms); the native T1 relaxation time is completely normal throughout the remainder of the myocardium. The clinical significance of this borderline finding is unclear. There is no evidence of 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 81 ml/m2 (normal range 69+/-14), the RVEDV is 192 ml (normal range 110+/-24), the RV end systolic volume index is 39 ml/m2 (normal range 22+/-8), and the RVESV is 94 ml (normal range 35+/-13). There are no regional wall motion abnormalities noted.Right AtriumThe right atrium is normal in size. Aortic ValveThe aortic valve opens widely and there is mild aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is no significant mitral regurgitation.Pulmonic ValveThe pulmonic valve opens widely. There is trace 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 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. Normal size left ventricle with normal systolic function (EF 57%). There is no late gadolinium enhancement, nor is there evidence of myocardial edema. However, the native T1 myocardial time is borderline elevated in the basal septum and inferior wall. The remainder of the myocardium has completely normal native myocardial T1. The clinical significance of this borderline finding in the setting of a family history of dilated cardiomyopathy is not clear.2. Normal size right ventricle with normal systolic function (EF 51%). No regional wall motion abnormalities.3. Mild aortic regurgitation. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
