19 year old man with history of palpitations, referred for cardiac MRI to evaluate for structural heart disease. Left VentricleThe left ventricle is mildly dilated with low normal systolic function. The overall LV ejection fraction is 56%, the LV end diastolic volume index is 109 ml/m2 (normal range: 74+/-15), the LVEDV is 210 ml (normal range 142+/-34), the LV end systolic volume index is 45 ml/m2 (normal range 25+/-9), the LVESV is 87 ml (normal range 47+/-19), the LV mass index is 45 g/m2 (normal range 85+/-15), and the LV mass is 86 g (normal range 164+/-36). There are no regional wall motion abnormalities present. Wall thickness is normal without evidence of asymmetric hypertrophy. 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 1025 ms in the basal septum, which is within normal limits. There is no myocardial iron overload.Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is mildly dilated with normal systolic function. The overall RV ejection fraction is 50%, the RV end diastolic volume index is 124 ml/m2 (normal range 82+/-16), the RVEDV is 238 ml (normal range 142+/-31), the RV end systolic volume index is 62 ml/m2 (normal range 31+/-9), and the RVESV is 119 ml (normal range 54+/-17).Right AtriumThe right atrium is normal in size.Aortic ValveThe aortic valve opens widely, and there is mild aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is trivial 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. The sinus of Valsalva measures 26 x 26mm. The ascending aorta is 22 x 23mm. There is no evidence of coarctation or aneurysmal disease of the aorta.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. Mild biventricular dilation with low normal systolic function. (LVEF 56%, RVEF 50%). 2. No evidence of late gadolinium enhancement to suggest underlying myocardial fibrosis, infiltration or inflammation. 3. Mild aortic regurgitation.4. Normal dimensions of the aortic root and ascending aorta. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
