Infective endocarditis presenting as ST-elevation myocardial infarction: an angiographic diagnosis

Abstract

While systemic embolic events occur with relative frequency in infective endocarditis (IE), coronary embolization remains an uncommon cause of ST elevation myocardial infarction. Herein we report a case of ventricular fibrillation and anterior ST elevation myocardial infarction occurring in a patient initially presenting with septic shock. Angiography proved diagnostic for IE of a native bicuspid aortic valve complicated by root abscess and left anterior descending artery occlusion. Histologic examination of the embolectomy specimen from the left anterior descending artery confirmed the presence of thrombus and bacteria. The present case highlights difficulties in identifying and managing patients with coronary embolism of vegetations from IE.
