Abstract
Our case was initially admitted with presumptive diagnosis of Non-ST
elevated myocardial infarction in congestive heart failure and was later
found to have large left atrial (LA) mass. Apart from complete
echocardiography study, we took help of multimodality imaging to better
characterise this LA mass.However we did not have a confirmed diagnosis.
Cardiac surgery was performed and surprisingly revealed large LA mass
with pockets of fresh blood inside LA. Pathological specimen confirmed
the presence of hematoma ruling out other atrial neoplasms. Though
contrast echocardiography and cardiac magnetic resonance imaging were
closest to intra-operative diagnoses, In the absence of any
pre-disposing factors, final diagnosis was made at surgery and
histopathological diagnosis.
