  • Title: [Floating thrombus of the right atrium in acute pulmonary embolism. Clinical, echocardiographic aspects and therapeutic sequelae].
    Author: Taupin JM, Chapoutot L, Metz D, Ouzan J, Pollet E, Elaerts J, Bajolet A.

    Abstract:
    The performance of a systematic sonocardiography in all our patients hospitalized since January 1985 for pulmonary embolism, has enabled to discover five cases of floating thrombus of the right atrium. Three patients presented an abnormal auscultation, with one of them presenting a tricuspid wedge syndrome. On the sonogram, the aspect of the thrombus, "coil or ball-shaped", floating in the atrial cavity, sometimes prolapsed through the tricuspid valve, associated with the signs of a pulmonary heart, enables to rule out other right intraatrial masses. Pulmonary angiography seems contra-indicated because of the risk of embolus of this thrombus, the migration of which may be fatal. Embolectomy, under extra-corporeal circulation (heart-lung pump) with examination of the right cavities appears to be the treatment of choice.
