25 year old with history of syncope and premature ventricular contractions presenting for cardiac assessment after syncopal episode. Left VentricleThe left ventricle is mildly enlarged with low normal LV systolic function. The overall LV ejection fraction is 54 %, the LV end diastolic volume index is 118 ml/m2 (normal range: 74+/-15), the LVEDV is 227 ml (normal range 142+/-34), the LV end systolic volume index is 56 ml/m2 (normal range 25+/-9), the LVESV is 105 ml (normal range 47+/-19). 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.Left AtriumThe left atrium is is normal in size. Right VentricleThe right ventricle is in the upper limit of normal in size with normal systolic function. The overall RV ejection fraction is 51 %, the RV end diastolic volume index is 118 ml/m2 (normal range 82+/-16), the RVEDV is 108 ml (normal range 142+/-31), the RV end systolic volume index is 58 ml/m2 (normal range 31+/-9), and the RVESV is 108 ml (normal range 54+/-17). No regional wall motion abnormalities are noted.Right AtriumThe right atrium is mildly enlarged.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 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 mildly enlarged with low normal systolic function (LVEF 54%). 2. The right ventricle is in the upper limit of normal in size with normal systolic function (RVEF 51%). 3. There are no regional RV wall motion abnormalities.4. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process.5. Based on this CMR, this does not meet any major MRI criteria for ARVC.
