Introduction In recent decades, the incidence of atrial fibrillation (AF) has increased exponentially worldwide., This comorbidity is directly related to cardioembolic events, and oral anticoagulation is considered the gold standard treatment for its prevention. Although oral anticoagulation is effective in preventing ischemic stroke, warfarin is contraindicated in 14% to 44% of patients at risk for cardioembolic stroke; nevertheless, even in eligible patients, only 54% are anticoagulated. Currently, direct-acting oral anticoagulants (DOAC) are preferable as preventive therapy for ischemic stroke; however, […]

The recent use of specific CT-angio protocols to evaluate thrombi and late imaging capture has significantly improved its sensitivity and specificity, which reaches near 100% in some series,, […]
