[Thromboses of the right cardiac cavities: echocardiographic diagnosis and therapeutic indications apropos of 2 cases and review of the literature].

Two cases of pulmonary emboli are reported: a thrombus was detected by echocardiography in the right atrium in the first case and in the right ventricle in the second. Following a review of the 28 cases published to date, criteria are given for distinguishing between those thrombi embolizing from the peripheral veins and those arising in the right cavities of the heart. Therapeutic recommendations are also given.
