39 year old woman with cardiomyopathy and echo suggesting 10% decrease in LVEF. Patient referred for reassessment of LVEF. Left VentricleThe left ventricle is severely dilated with mildly reduced systolic function. The overall LV ejection fraction is 42%, the LV end diastolic volume index is 113 ml/m2 (normal range: 65+/-11), the LVEDV is 216 ml (normal range 109+/-23), the LV end systolic volume index is 66 ml/m2 (normal range 18+/-5), the LVESV is 126 ml (normal range 31+/-10), the LV mass index is 43 g/m2 (normal range 67+/-11), and the LV mass is 81 g (normal range 114+/-24). There is abnormal septal motion consistent with bundle branch block. Native myocardial T1 times are within normal limits.Left AtriumThe left atrium is dilated.Right VentricleThe right ventricle is normal in size and systolic function. The overall RV ejection fraction is 62%, the RV end diastolic volume index is 83 ml/m2 (normal range 69+/-14), the RVEDV is 158 ml (normal range 110+/-24), the RV end systolic volume index is 32 ml/m2 (normal range 22+/-8), and the RVESV is 60 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 no obvious pericardial disease.Extracardiac FindingsRenal cysts are noted (also present on prior study). 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. Severe left ventricular dilation with mildly reduced systolic function (LVEF 42%) with normal native myocardial T1 relaxation times suggesting the absence of significant underlying myocardial fibrosis or inflammation. 2. Normal right ventricular size and systolic function (RVEF 62%). 3. When compared to prior study from 1/26/2016, no change in LVEF.
