18 year old male with a history of palpitations and tachycardia, and family history of RV dysplasia (cousin). Referred for cardiovascular MRI to evaluate for right ventricular dysplasia. Left VentricleThe left ventricle is normal in size and systolic function. The overall LV ejection fraction is 59%, the LV end diastolic volume index is 89 ml/m2 (normal range: 74+/-15), the LVEDV is 180 ml (normal range 142+/-34), the LV end systolic volume index is 38 ml/m2 (normal range 25+/-9), the LVESV is 77 ml (normal range 47+/-19), the LV mass index is 75 g/m2 (normal range 85+/-15), and the LV mass is 152 g (normal range 164+/-36). 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 normal in size. Right VentricleThe right ventricle is normal in size and systolic function without focal wall motion abnormality. The overall RV ejection fraction is 57%, the RV end diastolic volume index is 79 ml/m2 (normal range 82+/-16), the RVEDV is 191 ml (normal range 142+/-31), the RV end systolic volume index is 34 ml/m2 (normal range 31+/-9), and the RVESV is 69 ml (normal range 54+/-17).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. Left ventricle is normal in size and systolic function (LVEF 59%) without evidence of underlying myocardial fibrosis, inflammation, or infiltration. 2. Right ventricle is normal in size and systolic function (RVEF 57%) without cardiac MRI evidence of arrhythmogenic right ventricular dysplasia. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
