36 year old woman with recent of chest pain, intermittent first degree AV block, referred for cardiac MRI for further evaluation.MEDICATIONS: 75 mg Aminophyllin, 0.4 mg Regadenoson First Pass PerfusionDuring hyperemia, no perfusion defects were present. Viability/ Myocardial ScarThere was no late gadolinium enhancement noted suggesting that there is no prior myocardial infarction, fibrosis, inflammation, or infiltration. The entire myocardium is viable. Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 68%, the LV end diastolic volume index is 84 ml/m2 (normal range: 65+/-11), the LVEDV is 165 ml (normal range 109+/-23), the LV end systolic volume index is 27 ml/m2 (normal range 18+/-5), the LVESV is 53 ml (normal range 31+/-10), the LV mass index is 36 g/m2, and the LV mass is 70 g. There are no regional wall motion abnormalities present. No intracardiac thrombus. 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 68%, the RV end diastolic volume index is 77 ml/m2 (normal range 69+/-14), the RVEDV is 151 ml (normal range 110+/-24), the RV end systolic volume index is 25 ml/m2 (normal range 22+/-8), and the RVESV is 48 ml (normal range 35+/-13). 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.AortaThe aortic root is normal in size. There is a left sided aortic arch with a common origin of the innominate and left common carotid arteries.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 pericardial effusion.
1. No perfusion defects/ "ischemia" present during hyperemia.2. No prior myocardial infarction. The entire myocardium is viable.3. Normal LV size and systolic function (LVEF 68%).4. Normal RV size and systolic function (RVEF 68%).I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
