[Left atrial myxoma revealed by saddle occlusion of the aortic carrefour (author's transl)].

A case of a left atrial myxoma revealed a saddle occlusion of aortic carrefour is reported. The embolus has been surgically removed and histology allowed to recognise its myxomatous nature, suggesting source for left atrial cavity. Cardiac catheterisation and angiocardiography confirmed the presence of atrial tumor, which has been successfully excised. Embolisation is referred to villous, friable surface of the neoplasm. Employment of echocardiography in patients with arterial emboli from unknown etiology is highly recommended.
