Acute myocardial infarction caused by coronary tumor embolism from uterine leiomyosarcoma: a case report

While most AMI events result from thrombotic occlusion and respond to anticoagulation, tumor emboli require mechanical intervention. Aspiration thrombectomy proved effective in this case. Clinicians should recognize that tumor embolism can induce AMI even in previously unreported cancer types, as pulmonary metastases may invade the pulmonary veins enabling tumor fragments to enter systemic circulation. Early recognition and intervention are critical for survival in these patients. Tumor embolism should be considered in the differential diagnosis of patients with cancer presenting with unexplained chest pain or dyspnea.
