[A giant left atrial myxoma as a cause of a low cardiac output syndrome: a case report].
ABSTRACT A case of a 75-year-old female with a giant left atrial myxoma (54 x 42 mm in transthoracic echocardiography) is presented. She remained in a stable condition, however, developed a low cardiac output syndrome shortly after echocardiographic examination. This was caused by tumour displacement from the atrial wall into the left ventricle. The patient underwent urgent surgery during which the tumour was successfully removed. Histopathological examination confirmed the diagnosis of myxoma. Six months after surgery the patient is doing well.
