12 year old female with congenital dysplastic tricuspid valve and tricuspid regurgitation referred for cardiovascular MRI as part of a research study Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 56%, the LV end diastolic volume index is 77 ml/m2, the LVEDV is 118 ml, the LV end systolic volume index is 34 ml/m2, the LVESV is 52 ml, the LV mass index is 63 g/m2, and the LV mass is 56 g. Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is moderately dilated with mildly reduced systolic function. The overall RV ejection fraction is 46%, the RV end diastolic volume index is 111 ml/m2, the RVEDV is 170 ml, the RV end systolic volume index is 60 ml/m2, and the RVESV is 91 ml. Right AtriumThe right atrium is severely dilated. 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 is thickened with elongated leaflets, and mild prolapse of the anterior and posterior leaflets. The coaptation point and the septal leaflet a mildly apically displaced. There is severe 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 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 left ventricular size and systolic function (LVEF 56%)2. Moderately dilated right ventricle with mildly reduced systolic function (RVEF 46%, RVEDVi 111 mL/m2)3. The tricuspid valve is thickened with elongated leaflets, mild prolapse of the anterior and posterior leaflets, The coaptation point and the septal leaflet a mildly apically displaced. There severe tricuspid regurgitation4. Severe right atrial enlargement.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
