Coronary embolism (CE) is the underlying cause of 3% acute coronary syndromes but frequently overlooked in differential diagnoses syndromes. The CE may be direct (left sided from native or prosthetic heart valve, left atrium, atrial appendage pulmonary venous bed), paradoxical (from circulation through a patent foramen ovale, septal defect, ventricular defects, cyanotic congenital defects arteriovenous malformations), iatrogenic (following cardiac interventions. In patients with fibrillation (AF), (LAA) ligation during mitral valve surgery has long been recommended to decrease future risk embolic events such as myocardial infarction ischemic stroke. Recently, Aryana et al reported that AF who underwent surgical LAA, presence incomplete was associated significantly higher stroke/systemic embolization than complete (24% vs 2%).
