Myocardial infarction with thrombus formation during prolonged intense exercise

We present the case of a healthy young white man, who suddenly complained of strong pain in the lower extremities while he was cycling. An emergency bilateral femoral thromboembolectomy was carried out and thrombotic material was obtained. A two-dimensional echocardiogram showed a mobile mass adhered to the apex. Pathological study of the mass revealed a small myocardial infarction with thrombus.
