20 year old woman with history of near syncope and precordial T-wave inversions on ECG who presents for cardiac MRI to evaluate for possible ARVC. Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 59%, the LV end diastolic volume index is 78 ml/m2 (normal range: 65+/-11), the LVEDV is 152 ml (normal range 109+/-23), the LV end systolic volume index is 32 ml/m2 (normal range 18+/-5), the LVESV is 62 ml (normal range 31+/-10), the LV mass index is 31 g/m2 (normal range 67+/-11), and the LV mass is 61 g (normal range 114+/-24). 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 with normal systolic function. The overall RV ejection fraction is 61%, the RV end diastolic volume index is 77 ml/m2 (normal range 69+/-14), the RVEDV is 149 ml (normal range 110+/-24), the RV end systolic volume index is 30 ml/m2 (normal range 22+/-8), and the RVESV is 59 ml (normal range 35+/-13). There are no regional wall abnormalities. Right AtriumThe right atrium is normal in size. Aortic ValveThe aortic valve opens widely and there is no significant aortic regurgitation. Coronary Arteries:The ostium of the left main coronary arises normally from the left cusp. The ostium of the right coronary artery arises normally from the right cusp. 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 trivial 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. Normal size left ventricle with normal systolic function (LVEF 59%) without evidence of underlying myocardial fibrosis, inflammation, or infiltration.2. Normal size right ventricle with normal systolic function (RVEF 61%). No regional wall motion abnormalities. No MRI evidence of arrhythmogenic right ventricular cardiomyopathy. 3. Normal origin of the coronary arteries.4. No evidence of structural heart disease. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
