title: [Posttraumatic infarction with a surgically treated floating thrombus of the left ventricle. Apropos of a case].
abstract: Forty-two days after severe thoracic trauma which had led to thrombosis of the left renal artery and to nephrectomy, a 22 year old patient developed anterior wall infarction. Echocardiography and coronary and left ventricular angiography showed distal occlusion of the left anterior descending artery and the presence of a large, mobile thrombus at the left ventricular apex. The thrombus was removed surgically without any complications but a small thrombus adherent to the ventricular scar was observed postoperatively. After a discussion on the different possible physiopathological mechanisms, the authors conclude that the patient probably suffered primary myocardial contusion which led to secondary occlusion of the LAD artery, late myocardial infarction and extension of the initial intraventricular thrombus. This case illustrates the value of two-dimensional echocardiography in the detection and follow-up of ventricular thrombosis.
