title: [Detection by echocardiography of a thrombus of the right cavities in acute pulmonary embolism].
abstract: Echocardiography evaluates the severity of acute pulmonary embolism from its repercussions on haemodynamics. However, many authors have reported the discovery of thrombosis in the right heart cavities of patients with acute pulmonary embolism. In order to assess the frequency of intracavitary thrombosis and to evaluate the practical problems it raises, we have systematically examined by echocardiography 84 patients hospitalized for severe, acute pulmonary embolism (mean Miller's score: 21). In this series of 39 men and 45 women (mean age 62 years), 9 thrombi were detected, i.e. an incidence of 11%. Depending on the ultrasonographic images they presented, these patients were divided into two groups: 1. Six patients with low mobility thrombi attached to the cardiac wall. All benefited from a medical treatment consisting of heparin in 4 cases and a thrombolytic drug in 2 cases. There was no clinical evidence of recurrent embolism. Echocardiography showed complete disappearance of the thrombi in 5 of these 6 patients and partial regression under heparin therapy in one. 2. Three patients with a large and mobile thrombus threatening to prolapse through the tricuspid valve during atrial systole. It seemed rational to regard such thrombi as carrying a high risk of embolism with recurrences, especially since they had formed in patients already with severe pulmonary embolism. This view was confirmed by a search in the literature which yielded a 40% death rate figure when these thrombi were associated with pulmonary embolism. This high mortality, however, can be reduced by diagnostic and therapeutic measures.(ABSTRACT TRUNCATED AT 250 WORDS)
