33-year-old female with Gitelman's Syndrome, hypomagnesemia, sinus tachycardia, palpitations, and PVC's s/p ablation 4/2014 (RVOT focus). MRI for further evaluation of possible RV dilation on TTE. Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 58%. The LVEDV is 111 ml (normal range 109+/-23), LV end diastolic volume index is 56 ml/m2 (normal range: 65+/-11), LVESV is 46 ml (normal range 31+/-10), and LV end systolic volume index is 23 ml/m2 (normal range 18+/-5). The LV mass is 88 g (normal range 114+/-24) and the LV mass index is 44 g/m2 (normal range 67+/-11). 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 normal in size.Right VentricleThe right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 50%, the RVEDV is 148 ml (normal range 110+/-24), the RV end diastolic volume index is 74 ml/m2 (normal range 69+/-14), the RVESV is 74 ml (normal range 35+/-13), and the RV end systolic volume index is 37 ml/m2 (normal range 22+/-8). No focal right ventricular wall motion abnormalities or aneurysms. No evidence of fatty or fibrous infiltration into the RV.Right AtriumThe right atrium is normal in size. Aortic ValveThe aortic valve is trileaflet, opens widely and there is no significant aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is mild 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.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-sized left ventricle with normal systolic function (LVEF 58%).2. Normal-sized right ventricle with normal systolic function (RVEF 50%) without any cardiac MRI features of arrhythmogenic right ventricular dysplasia.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
