William Heberden (1710--1801), in 1768, described angina pectoris, the classic symptom of ischemic heart disease, 150 years after the discovery of the coronary circulation by William Harvey (1578-1657). Another 110 years had elapsed before the first antemortem diagnosis (confirmed at autopsy) of coronary thrombosis was reported by Adam Hammer in 1878. The patient was a 34 year old man who died some 19 hours after a sudden collapse. Although the patient's clinical features were atypical (such as the absence of angina and the presence of complete heart block) and the autopsy showed vegetative aortic endocarditis that appeared to be causally related to the thrombotic coronary occlusion, Hammer's astute and carefully reasoned bedside diagnosis was history-making and deserves to be so recognized.

Four cases of purulent complications in the heart following acute myocardial infarction are described. Fever occurred during the first week after coronary occlusion. In one case thrombophlebitis at an infusion site was followed by purulent pericarditis. One patient had an infected mural thrombus with peripheral septic embolic, and two suffered from streptococcal endocarditis. The association between these infections and recent acute myocardial infarction could be related to tissue necrosis and local thrombosis, but the increasing risk of bacteremia following invasive monitoring procedures in these patients is a risk factor that should not be ignored.

A ruptured myocardial infarct secondary to total coronary occlusion by a fragment of nonbacterial thrombotic endocarditis produced sudden, unexpected death in a nearly asymptomatic 82-year-old man who harbored two malignant neoplasms.

Acute coronary syndromes in the setting of infective endocarditis may be the result of coronary compression secondary to periannular aortic valve complications, coronary embolism, obstruction of the coronary ostium due to a large vegetation, coronary atherosclerosis, and severe aortic insufficiency. External coronary artery compression as a result of infective endocarditis is a rare and lethal finding with few reported cases available in the medical literature. We present a rare occurrence of an acute coronary syndrome occurring in the setting of a bioprosthetic aortic valve abscess in which there was no complete coronary occlusion visualized and given the patient's recent unremarkable catheterization and findings of diffuse tapering of the proximal left coronary system, the most likely etiology was external compression secondary to the known aortic root abscess, which caused myocardial ischemia, and was confirmed during surgery. Although uncommon, external compression should be considered in the differential diagnosis of acute coronary syndrome in this setting and coronary angiography can be diagnostic of this entity.

Coronary artery septic embolization is a rare, but severe complication of infective endocarditis involving the leftside of the valves. The first case mentioned in the literature was a postmortem finding of a left anterior descending coronary artery occlusion by a vegetation fragment. Since this case, there have been several therapeutic strategies published with this clinical setting including medical treatment, percutaneous coronary angioplasty addressing coronary occlusion, surgical intervention for both the infected valve and coronary embolization, and hybrid procedures with transcatheter septic embolus aspiration followed by surgical valvular interventions. Out of the three interventions mentioned, the latter provided the best results and was in concordance with results observed in a case of mitral valve infected endocarditis complicated with acute occlusion of the left anterior descending coronary artery in patient whose comorbidities included hypertrophic obstructive cardiomyopathy. A transcatheter left anterior descending coronary artery embolus aspiration was performed , followed by a surgical mitral valve replacement and septal myectomy with an uneventful postoperative course. Although rare, this severe complication of infective endocarditis has a specific clinical course and therapeutic strategy, and in our opinion, it could be mentioned as a separate entity among embolic complications of infective endocarditis in future guidelines. Previously published cases suggest that the hybrid intervention might be the therapy of choice for this clinical setting; however, larger studies are necessary for confirmation.
