38 year old woman with non-ischemic cardiomyopathy referred for interval assessment. Left VentricleThe left ventricle is severely dilated with mild to moderately reduced systolic function. The overall LV ejection fraction is 40%, the LV end diastolic volume index is 122 ml/m2 (normal range: 65+/-11), the LVEDV is 230 ml (normal range 109+/-23), the LV end systolic volume index is 73 ml/m2 (normal range 18+/-5), the LVESV is 139 ml (normal range 31+/-10), the LV mass index is 64 g/m2 (normal range 67+/-11), and the LV mass is 120 g (normal range 114+/-24). Abnormal septal wall motion and dyssynchrony consistent with left bundle branch block. LV dysfunction is global with regional variation. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process. There is no evidence of acute inflammation or edema on T1 or T2 imaging. The native myocardial T1 time was mildly elevated in the interventricular septum (1,116msec) and borderline in the inferolateral wall (1,077msec).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 64%, the RV end diastolic volume index is 76 ml/m2 (normal range 69+/-14), the RVEDV is 144 ml (normal range 110+/-24), the RV end systolic volume index is 28 ml/m2 (normal range 22+/-8), and the RVESV is 52 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.Pulmonic ValveThe pulmonic valve opens widely. There is no significant pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is trace 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 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. The left ventricle is severely dilated with mild to moderately reduced systolic function. The overall LV ejection fraction is 40%. Abnormal septal wall motion and dyssynchrony consistent with left bundle branch block. LV dysfunction is global with regional variation. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process. There is no evidence of acute inflammation or edema on T1 or T2 imaging. The native myocardial T1 time was mildly elevated in the interventricular septum.2. The right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 64%.3. Compared to prior cardiac MRI on 3/10/2011, the LVEF is slightly lower. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
