Between 1978 and 1986, atrial heart tumors were found in 21 of our patients, all of them subsequently underwent surgery. Pathological-histological examination in 20 patients confirmed the diagnosis of a myxoma; the one remaining case was a female patient with primary cardiogenic osteosarcoma. Of the 20 patients, 15 (75%) were females; in four female patients (20%) the tumor was localized in the right atrium. The main symptoms and findings were elevated erythrocyte sedimentation rates (80%), stress-induced dyspnea or paroxysmal dyspnea (71% resp.), and diastolic mitral or tricuspid murmurs (62%). The patient with osteosarcoma died of cachexia on the basis of generalized diffuse metastases. One female patient with a preoperative history of severe left ventricular impairment on the basis of dilative cardiomyopathy died 5 weeks after surgery. Relapse of atrial myxoma has not yet occurred during follow-up since 1978.
