20 year old with history of suspicion for median arcuate ligament syndrome and syncope presenting for cardiac evaluation. Left VentricleThe left ventricle is normal in size and systolic function. The overall LV ejection fraction is 63%, the LV end diastolic volume index is 79 ml/m2 (normal range: 65+/-11), the LVEDV is 114 ml (normal range 109+/-23), the LV end systolic volume index is 29 ml/m2 (normal range 18+/-5), the LVESV is 42 ml (normal range 31+/-10), the LV mass index is 33 g/m2 (normal range 67+/-11), and the LV mass is 48 g (normal range 114+/-24). There are no regional wall motion abnormalities present. Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is normal in size and systolic function. The overall RV ejection fraction is 58%, the RV end diastolic volume index is 80 ml/m2 (normal range 69+/-14), the RVEDV is 115 ml (normal range 110+/-24), the RV end systolic volume index is 32 ml/m2 (normal range 22+/-8), and the RVESV is 49 ml (normal range 35+/-13). No regional wall motion abnormalities or aneurysms in the RV free wall.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 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 normal in size and systolic function. The overall LV ejection fraction is 63%. 2. The right ventricle is normal in size and systolic function. The overall RV ejection fraction is 58%. No regional wall motion abnormalities or aneurysms in the RV free wall. No cardiac MRI evidence for right ventricular arrhythmogenic cardiomyopathy.3. The presence of myocardial fibrosis can not be determined on this scan because patient refused contrast administration.
