19 year old man with history of frequent palpitations and mildly reduced LV function on transthoracic echocardiogram, referred for cardiac MRI. Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 56%, the LV end diastolic volume index is 96 ml/m2 (normal range: 74+/-15), the LVEDV is 186 ml (normal range 142+/-34), the LV end systolic volume index is 42 ml/m2 (normal range 25+/-9), the LVESV is 82 ml (normal range 47+/-19), the LV mass index is 51 g/m2 (normal range 85+/-15), and the LV mass is 99 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.The native T1 myocardial relaxation time is 944ms which is normal.There is no myocardial iron overload. 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 52%, the RV end diastolic volume index is 104 ml/m2 (normal range 82+/-16), the RVEDV is 203 ml (normal range 142+/-31), the RV end systolic volume index is 50 ml/m2 (normal range 31+/-9), and the RVESV is 98 ml (normal range 54+/-17). There are no regional RV wall motion abnormalities noted.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 mild pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is mild tricuspid regurgitation.AortaThere is a left sided aortic arch with a normal brachiocephalic branching pattern. The aortic root is normal in size.Coronary Arteries:The left main coronary artery arises normally and gives rise to the left anterior descending and left circumflex arteries. The right coronary artery arises normally.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. Normal LV size with normal systolic function (EF 56%) without evidence of underlying myocardial fibrosis, inflammation, or infiltration.2. Normal RV size with normal systolic function (EF 52%). There are no regional wall motion abnormalities in the right ventricle without MRI evidence of arrhythmogenic right ventricular dysplasia.3. Normal origins of the coronary arteries. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
