23 year old with history of recurrent syncope Left VentricleThe left ventricle is upper normal in size with lower normal systolic function. The overall LV ejection fraction is 54%, the LV end diastolic volume index is 86 ml/m2 (normal range: 65+/-11), the LVEDV is 163 ml (normal range 109+/-23), the LV end systolic volume index is 75 ml/m2 (normal range 18+/-5), the LVESV is 39 ml (normal range 31+/-10). 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. LGE imaging was limited by motion artifact. There are prominent trabeculations in the LV apex.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 54%, the RV end diastolic volume index is 82 ml/m2 (normal range 69+/-14), the RVEDV is 156 ml (normal range 110+/-24), the RV end systolic volume index is 38 ml/m2 (normal range 22+/-8), and the RVESV is 73 ml (normal range 35+/-13). There are no focal regional wall motion abnormalities to suggest arrhythmogenic right ventricular cardiomyopathy. 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 trace 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 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. Upper normal left ventricular size with lower normal systolic function (LVEF 54%). There are prominent trabeculations in the LV apex, however the quantitative compaction ratio criteria are not met for the MRI diagnosis of non-compaction.2. Normal right ventricular size and systolic function (RVEF 54%)3. No MRI evidence of arrhythmogenic right ventricular dysplasia. 4. Late gadolinium imaging limited by motion artifact, however, no obvious scar, inflammation or infarction seen on LGE imaging.
