Acute myocardial infarction caused by tumor embolus originating from upper tract urothelial carcinoma: a case report

Abstract

Abstract Coronary emboli from malignant tumors rarely cause acute myocardial infarction. We report the case of a patient with tumor embolism from an upper tract urothelial carcinoma that caused acute myocardial infarction via a patent foramen ovale. Coronary blood flow was restored by embolus aspiration without stenting. Clinicians must consider malignant tumor embolism as a possible cause of acute myocardial infarction.
