Atrial fibrillation with mitral valve disease has long been considered a stroke risk factor. Recurrent embolism occurs in 30-65% of patients with rheumatic mitral valve disease who have a history of a previous embolic event. Most of these recurrences (around 60%) develop within the first year. Mechanical prosthetic valves are a prime site for thrombus formation and patients with these valves require anticoagulation [7, 38]. Bacterial endocarditis can cause stroke as well as intracerebral mycotic aneurysms. Because mycotic aneurysms are inflammatory defects in the vessel wall, treatment with systemic thrombolysis or anticoagulation can lead to rupture with subsequent lobar hemorrhage. Nonbacterial, or marantic, endocarditis is also associated with multiple embolic strokes. This condition is most common in patients with mucinous carcinoma and may be associated with a low-grade disseminated intravascular coagulation. A nonbacterial endocarditis, called Libman-Sacks endocarditis, occurs in patients with systemic lupus erythematosus (SLE) [42],...
