Histopathological examination of the surgical specimens confirmed
fragments of organized thrombus and adjacent normal myocardial wall.
There was no evidence of active inflammation, hydaditosis, endocarditis,
amyloidosis, tumor, vascular malformation and cultures of the specimen
were negative for bacteria and fungus. Postoperative course was
uneventful. Predischarge TTE showed no residual hematoma and an intact-
patched LA wall with no mitral insufficency (Figure 4).
