Paradoxical embolism in Ebstein’s anomaly

Abstract

A 26-year-old man with Ebstein’s anomaly had cerebellar infarction due to paradoxical embolism. Ebstein’s anomaly is characterized by a downward displacement of the tricuspid valve into the right ventricle due to anomalous attachment of the tricuspid leaflets. Echocardiography is the method of choice to diagnose Ebstein’s anomaly on its own or in association with other heart defects. Paradoxical embolism is a potential complication whenever a right to left shunt exists (for example, atrial septal defect). Ebstein’s anomaly diagnosed in adult life is a benign and stable disease, particularly if the patient is asymptomatic; surgical correction must be performed if the patient becomes symptomatic because of either paradoxical embolism or worsening of the tricuspid regurgitation
