Atrial appendage aneurysm is a rare cardiac disease and may be complic
ated by embolic events and rhythm disturbances. We describe a case of
a congenital left atrial aneurysm, presenting with ct cerebrovascular
accident in a 57-year-old female. The diagnosis was made by transesoph
ageal echocardiography, which revealed the presence of intraaneurysmal
thrombi. The patient initially received anticoagulant therapy and the
thrombi were resolved. Subsequently, she was successfully operated on
and the aneurysm was removed. This is tile first report of thrombi re
solution. in a left atrial appendage aneurysm.
