27 year old female with history of PVC, now with mildly reduced LVEF, eval for PVC induced cardiomyopathy Left VentricleThe left ventricle is mildly dilated with normal global systolic function. The overall LV ejection fraction is 56%. The LVEDV is 164 ml (normal range 109+/-23), LV end diastolic volume index is 89 ml/m2 (normal range: 65+/-11), LVESV is 71 ml (normal range 31+/-10), and LV end systolic volume index is 39 ml/m2 (normal range 18+/-5). The LV mass is 103 g (normal range 114+/-24) and the LV mass index is 56 g/m2 (normal range 67+/-11). 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. Native T1-mapping is not interpretable due to arrhythmia or gating error. Left AtriumThe left atrium is normal in size.Right VentricleThe right ventricle is mildly dilated with normal function. The overall RV ejection fraction is 64%, the RV end diastolic volume index is 104 ml/m2 (normal range 69+/-14), the RVEDV is 193 ml (normal range 110+/-24), the RV end systolic volume index is 38 ml/m2 (normal range 22+/-8), and the RVESV is 69 ml (normal range 35+/-13). No focal wall motion abnormality or aneurysm. Right AtriumThe right atrium is normal in size. Aortic ValveThe aortic valve is trileaflet, 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 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. Mild left ventricular dilation with normal systolic function (LVEF 56%) without evidence of underlying myocardial fibrosis, inflammation, or infiltration. 2. Mild right ventricular dilation with normal systolic function (RVEF 64%). No CMR evidence of arrhythmogenic right ventricular dysplasia. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
