A 44 year old female with history of heart surgery as an infant ?ASD repair. ECG showed WPW. Referred to cardiac MRI for further evaluation and to rule out ASD. Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 55%, the LV end diastolic volume index is 83 ml/m2 (normal range: 65+/-11), the LVEDV is 190 ml (normal range 109+/-23), the LV end systolic volume index is 37 ml/m2 (normal range 18+/-5), the LVESV is 86 ml (normal range 31+/-10), the LV mass index is 43 g/m2 (normal range 67+/-11), and the LV mass is 99 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.No intracavitary thrombus was seen.AtriaThe left atrium is normal in size. The LA volume is 71 ml.The right atrium is normal in size. The RA volume is 69 ml. No shunt was noted, no atrial septal defect.Qp:Qs normal (1.08).Right VentricleThe right ventricle is mildly dilated with mildly reduced systolic function. The overall RV ejection fraction is 48%, the RV end diastolic volume index is 106 ml/m2 (normal range 69+/-14), the RVEDV is 243 ml (normal range 110+/-24), the RV end systolic volume index is 54 ml/m2 (normal range 22+/-8), and the RVESV is 125 ml (normal range 35+/-13). Aortic ValveThe aortic valve is trileaflet, 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 pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is at least mild to moderate tricuspid regurgitation.AortaThere is a left sided aortic arch with a normal brachiocephalic branching pattern. The aortic root is normal in size (32 mm).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.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. The left ventricle is normal in size with normal systolic function, the LVEF is 55%. There is no late gadolinium enhancement.2. The right ventricle is mildly dilated with mildly reduced systolic function, the RVEF is 48%. 3. The left and right atria are normal in size.4. No hemodynamically significant atrial septal defect appreciated on this study. Qp:Qs normal (1.08).5. There is mild to moderate tricuspid regurgitation.
