94 year old male with incidentally noted right atrial vs. pericardial mass Left VentricleThe left ventricle is normal in size with hyperdynamic systolic function. The overall LV ejection fraction is 77%, the LV end diastolic volume index is 49 ml/m2 (normal range: 74+/-15), the LVEDV is 85 ml (normal range 142+/-34), the LV end systolic volume index is 11 ml/m2 (normal range 25+/-9), the LVESV is 19 ml (normal range 47+/-19), the LV mass index is 27 g/m2 (normal range 85+/-15), and the LV mass is 46 g (normal range 164+/-36). 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 mildly enlarged. Right VentricleThe right ventricle is normal in size with hyperdynamic systolic function. The overall RV ejection fraction is 73%, the RV end diastolic volume index is 68 ml/m2 (normal range 82+/-16), the RVEDV is 117 ml (normal range 142+/-31), the RV end systolic volume index is 19 ml/m2 (normal range 31+/-9), and the RVESV is 32 ml (normal range 54+/-17).Right AtriumThe right atrium is normal in size. There is lipomatous hypertrophy of the interatrial septum. The interatrial septum is aneurysmal. No atrial mass is seen.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.AortaThere is a left sided aortic arch with a normal brachiocephalic branching pattern. The aortic root is normal in size. The thoracic aorta is tortuous.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 FindingsMultiple hemangiomas and/or cysts in the liver. There are bilateral cysts in the kidneys. There is cholelithiasis and gallbladder sludge; mild gallbladder wall thickening . 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 size LV with hyperdynamic systolic function (EF 77%).2. Normal size RV with hyperdynamic systolic function (EF 71%).3. Aneurysmal interatrial septum with lipomatous hypertrophy. 4. No right atrial mass visualized. 5. Extra-cardiac findings as above.
