Infective endocarditis presenting with ST segment elevation.

Despite diagnostic and therapeutic advances, mortality and morbidity associated with infective endocarditis (IE) remains high. Congestive heart failure and complications such as septic embolization and aortic root abscess are the main causes. Although aortic root abscess is a common complication of IE involving the aortic valve, acute myocardial infarction (AMI) is a rare complication in patients with endocarditis, whether in the acute or later phase of infection. In most cases, the infarction is either anterior or anterolateral. To the best of the present authors' knowledge, only one case of infarction at a purely inferior site has been reported previously. In the present case, IE with an aortic root abscess presented clinically as an acute inferior wall myocardial infarction.
