Paradoxical embolization occurs when an embolus formed in the systemic venous circulation enters the systemic arterial circulation via an intracardiac shunt. The most common intracardiac shunt is a patent foramen ovale (PFO) present in approximately 25% of adults [1]. Other shunts which could allow for paradoxical embolization to occur include atrial septal defect, ventricular septal defect or extracardiac communications such as a pulmonary arteriovenous malformation [2].
