This report describes an uncommon and fatal case of myocardial infarction due to coronary embolus arising from vegetation in the aortic valve with a background of infective endocarditis (IE). There are various causes of fatal IE. Myocardial infarction due to septic emboli is rare. We report a case of sudden death in a 69-year-old woman with hyperlipidemia and no known cardiac disease. She had severe general weakness and was hospitalized for colonoscopy. The patient unexpectedly presented with cardiac arrest and died. The autopsy showed total occlusion of the left anterior descending artery by an embolus, which originated from the septic vegetation of the aortic valve. Myocardial infarction from septic emboli associated with IE can be fatal and manifested as the first presentation. In autopsy practice of deceased patients with IE, careful examination of the coronary arteries is required.

This article showcases a young patient who presented with STEMI secondary to septic emboli due to endocarditis with Abiotrophia Defectiva in the setting of a congenital bicuspid aortic valve. We aim to discuss current considerations for STEMI in young individuals including embolism due to IE, especially in patients with known or suspected congenital heart valve disease.

Infective endocarditis is a bacterial or fungal infection of the heart valves or endocardial surface, and it frequently forms vegetation and can lead to systemic embolism. Dislodged vegetation rarely results in coronary artery embolism (CAE) and subsequent acute myocardial infarction. A 43-year-old male patient was emergently brought to our hospital for suspected acute myocardial infarction. Coronary angiography was performed and it showed embolism in the left circumflex artery. Thrombus aspiration was performed during coronary angiography. Echocardiography showed formation of vegetation in the posterior leaflet of the mitral valve and multiple blood cultures showed Listeria monocytogenes. Infective endocarditis was diagnosed. Three weeks later, debridement of subacute bacterial endocarditis, mitral valve replacement, and tricuspid valvuloplasty were successfully conducted. Our findings suggest that CAE should be considered in the differential diagnosis of acute myocardial infarction. Aspiration of coronary embolus during coronary angiography followed by surgical intervention of diseased heart valves is a plausible strategy for managing CAE in infective endocarditis.

ST-elevation myocardial infarction (STEMI) is a rare and potentially fatal complication of infective endocarditis. We report the ninth case of embolic native aortic valve infective endocarditis causing STEMI and the first case to describe consecutive embolisms leading to infarctions of separate coronary territories. Through examination of this case in the context of the previous eight similar documented cases in the past, we find that infective endocarditis of the aortic valve can and frequently affect more than a single myocardial territory and can occur consecutively. Further, current treatment modalities for embolic infective endocarditis causing acute myocardial infarction are limited and unproven. This index case illustrates the potential severity of complications and the challenges in developing standardized management for such patients.

Coronary Embolism

Previous cases of coronary embolism as a cause of myocardial infarction (MI) in association with prosthetic mechanical valves have been reported, but the fact that the patient was not aware of the importance of maintaining anticoagulation therapy is relevant in this case. A 16-year-old female was referred for primary coronary intervention due to subacute anterolateral ST elevation MI, after she decided to discontinue warfarin therapy three weeks before. Coronary angiography showed distal occlusion of the left anterior descending coronary artery with an image suggesting embolic material. Conventional echocardiography demonstrated akinesia of anteroseptal, inferior, and posterior segments of the left ventricle, with severe systolic dysfunction, beyond the intraventricular thrombus. The presence of mechanic aortic prosthesis and no anticoagulation therapy are highly suggestive of coronary embolism as the cause of MI. This case report confirms that patient education is vital in our struggle to prevent this complication in high-risk patients.

The coronary angiographic (CAG) findings of ST elevation myocardial infarction (STEMI) in patients of coronavirus disease 2019 (COVID-19) range from increased coronary artery thrombus burden to normal coronaries due to STEMI mimics. Here we report the case of a 45-year-old gentleman who presented with evolved inferior wall myocardial infarction with ongoing angina along with mild COVID-19. CAG showed normal epicardial coronaries except for distal right posterior descending coronary artery (RPDA) 100% occlusion on careful examination. He was treated for the myocardial infarction with medical management along with treatment of COVID-19. The importance of our case is to highlight the possibility of distal total occlusion of small coronary branches which may be missed if not carefully looked for as a normal CAG in COVID-19 patient will require only supportive therapy, while the finding of distal 100% occlusion of RPDA deemed us to prescribe optimal medical therapy as per acute myocardial infarction protocol along with treatment for COVID-19.
