Filling defect in the left atrial appendage. This is not the typical site of myxoma (the major differential diagnosis). The patient is chronically fibrillating (atrial) thus thrombus is most likely.
Case Discussion
Clot in the left atrial appendage is a potential source of embolism producing ischemic stroke and infarction of other organs including the spleen, bowel and kidneys.
