8 year old male with pulmonic valve stenosis s/p balloon valvuloplasty. He also has a dysplastic tricuspid valve. Patient is participating in a clinical trial. Left VentricleThe left ventricle is normal in size and systolic function. The overall LV ejection fraction is 66%, the LV end diastolic volume index is 79 ml/m2 (normal range: 74+/-15), the LVEDV is 75 ml, the LV end systolic volume index is 27 ml/m2 (normal range 25+/-9), the LVESV is 26 ml, the LV mass index is 49 g/m2 (normal range 85+/-15), and the LV mass is 46 g. There are no regional wall motion abnormalities present.Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is severely dilated with normal systolic function. The overall RV ejection fraction is 57%, the RV end diastolic volume index is 148 ml/m2 (normal range 82+/-16), the RVEDV is 140 ml, the RV end systolic volume index is 63 ml/m2 (normal range 31+/-9), and the RVESV is 59 mlRight AtriumThe right atrium is significantly 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 severe pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely; however, the leaflets are thickened and possibly calcified. 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 dilated and significantly pulsatile. During diastole it is 24mm in diameter and during systole it is 31mm in diameter. Venous AnatomyThe SVC and IVC are normal in size and drain normally into the right atrium.PericardiumThere is no obvious pericardial disease.Extracardiac FindingsThymus tissue is noted. This 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 LV size and systolic function (LVEF 66%).2. Severe RV dilation (RVEDVi 148ml/m2) with normal systolic function (RVEF 57%).3. Severe tricuspid valve regurgitation.4. Severe pulmonic valve regurgitation. 5. Dilated main pulmonary artery.
