In agreement with classical data from the Institute of Pathology of the Armed Forces (Washington, DC), primary tumors of the heart, benign or malign, are found in 0.001% -0.28% of all of autopsies, and the myxomas represent 50% of the benign tumors of the heart 1 . Clinical experiences at two of the largest Brazilian institutions (InCor-USP and Dante Pazzanese Institute of Cardiology) demonstrate the wide prevalence of the heart myxomas as primary heart tumors. At InCor-USP, in a series of 50 patients treated over a period of 18 years, 84% of the myxomas were of the histological type 2 . At the Dante Pazzanese Institute of Cardiology, the experience was similar. Over a period of 28 years, with a series of 52 patients with heart tumors, 82.7% of the tumors were myxomas 3 . At the Ribeirão Preto Heart Hospital, over a period of 23 years, surgeons at the CECORP -Ribeirão Preto Specialized Heart and Lung Center operated on 7 patients for removal of heart tumors, 6 patients with myxomas and 1 patient with leiomyosarcoma metastasis. Among the 6 patients with heart myxomas, the age varied from 14 to 78 years, 4 were females, and all tumors were located at the left atrium. Although syncope is a symptom thoroughly described, resulting from myxoma left ventricular inflow obstruction, its incidence in the adolescent is rare, creating difficulties for the clinical evaluation of syncope in this age group. A unique case was reported in the literature of syncope as a consequence of left ventricle outflow obstruction, caused by a myxoma localized in this cardiac chamber 4 . A case of ischemic stroke in an 8-year-old female child has been reported in the Brazilian literature 5 . These data justify this case report of syncope in an adolescent caused by the presence of a left atrial heart myxoma that intermittently obstructed the mitral valve. Case ReportA 14-year-old female, resident of São Simão (SP), had a clinical cardiology appointment in April 2000 because of 3 episodes of syncope over the previous 3 months. During this interval of time, she was evaluated by a neurologist, without any diagnostic conclusion about the syncope. She was then directed to the cardiologist due to the presence of palpitations experienced at rest.During the first cardiology consultation, a syncope diagnosis was the main focus of the investigation. The clinical anamnesis revealed palpitations, a heart rate of 130 bpm, and low corporal weight with accentuated loss in the prior 3 months. The heart auscultation, by this time, did not show evidence of a heart murmur. With the clinical hypothesis of hyperthyroidism, thyroid hormone dosages and an electrocardiogram were requested. The hormonal function was normal. The electrocardiogram identified a sinus tachycardia and a possible left atrium enlargement. The diagnostic

Papillary fibroelastomas of the heart valves are benign, slow-growing, rare tumors of the heart. This tumor represents a potential cause of systemic embolism, stroke, myocardial infarction and sudden death. Early diagnosis is very important, as surgical excision of these tumors can prevent cerebrovascular and cardiovascular complications. Diagnosis is usually made by transesophageal echocardiogram. We describe two cases of patients with papillary fibroelastomas causing cardioembolic cerebral events, which underwent successful surgical treatment. The authors present a brief review of the literature. Keywords
