60 year old man with history of paroxysmal atrial fibrillation who is referred for cardiac MRI prior to planned atrial fibrillation ablation procedure. Left VentricleThe left ventricle is mild-moderately dilated with normal systolic function. The overall LV ejection fraction is 60%, the LV end diastolic volume index is 117 ml/m2 (normal range: 74+/-15), the LVEDV is 250 ml (normal range 142+/-34), the LV end systolic volume index is 47 ml/m2 (normal range 25+/-9), the LVESV is 101 ml (normal range 47+/-19), the LV mass index is 53 g/m2 (normal range 85+/-15), and the LV mass is 113 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 moderately dilated. The left atrial volume is 151mL (left atrial volume index 72mL/m2). There is no left atrial appendage thrombus.Right VentricleThe right ventricle is moderately dilated with normal systolic function. The overall RV ejection fraction is 50%, the RV end diastolic volume index is 133 ml/m2 (normal range 82+/-16), the RVEDV is 283 ml (normal range 142+/-31), the RV end systolic volume index is 66 ml/m2 (normal range 31+/-9), and the RVESV is 141 ml (normal range 54+/-17).Right AtriumThe right atrium is moderately dilated. The right atrial volume is 99mL (right atrial volume index 47mL/m2).Aortic ValveThe aortic valve opens widely and there is no significant aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is trivial 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 sinus of Valsalva measures 35mm. The ascending aorta is mildly dilated (41x42mm).Pulmonary VeinsAll four pulmonary veins drain normally into the left atrium.The dimensions of the individual pulmonary veins are as follows:RUPV : 20 x 19mmRLPV: 16 x 19mmLUPV: 16 x 16mmLLPV: 15 x 17mmPulmonary ArteryThe main pulmonary artery is upper 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-moderately dilated left ventricle with normal systolic function (EF 62%).2. Moderately dilated right ventricle with normal systolic function (EF 50%). 3. Moderate biatrial dilatation. 4. Mild ascending aorta dilation. 5. Pulmonary vein anatomy and dimensions as noted above. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
