title: [Left atrial extension of bronchial cancer diagnosed by echocardiography. Report of 2 cases].
abstract: The authors report 2 cases of left atrial extension of bronchial carcinoma detected by echocardiography. There have only been ten previous reports of echocardiography. There have only been ten previous reports of echocardiography detection of this complication as echocardiography is not requested systematically in patients with bronchial carcinoma. Left atrial metastasis is not uncommon at autopsy and the diagnostic value of echocardiography is excellent : the tumour appears as a hyperdense mass invading the roof of the left atrium through the pulmonary veins. Echocardiographic detection of left atrial extension of bronchial carcinoma is important because it implies a poor prognosis and because it may lead to a different therapeutic approach.
