Pancreatic tumors frequently metastasize widely, though it is rare to diagn
ose pancreatic cardiac metastases in the antemortem state. We report an unu
sual case of metastatic pancreatic adenocarcinoma to the fight atrium. Tran
sesophageal echocardiography showed that the tumor was attached to the supe
rior aspect of the right atrium, prolapsing through and obstructing the tri
cuspid valve In diastole and retracting back into the right atrium during s
ystole. The tumor was excised, and histologic examination confirmed the pre
sence of moderately differentiated adenocarcinoma with a papillary architec
tural pattern and with desmoplastic stroma, features comparable to the orig
inal primary pancreatic neoplasm.
