Myocardial infarction resulting from coronary embolism is a rare type of acute coronary syndrome, often going unnoticed. Distinguishing it from acute coronary syndromes arising from atherosclerosis is important, as it significantly influences the treatment approach. It is frequently associated with conditions that increase the risk of thromboembolism, such as infective endocarditis, atrial fibrillation, mitral valve disease, neoplasia and cardiac surgeries. We would like to present a case of coronary embolism involving a 42-year-old male with a history of rheumatic valve disease and atrial fibrillation who was admitted for acute chest pain. The diagnosis was confirmed through coronary angiography.
