title: Isolated papillary endothelial hyperplasia in the left atrial appendage.
abstract: Papillary endothelial hyperplasia (PEH) of the heart is extremely rare. This report describes a case of left atrial appendage PEH discovered by intraoperative palpation during mitral valve repair in a 69-year-old woman. The lesion was treated successfully by surgical excision of the left atrial appendage. Immunohistochemistry analysis confirmed the diagnosis and the patient was discharged without any complications.
