Although rare, paradoxic emboli can occur in patients with cardiac defects (usually atrial septal defect), who are at risk for the passage of emboli to the arterial circulation and resultant stroke or embolization of a peripheral artery. Patients can present after cardiac failure occurs late in life, with resultant bedrest that increases the risk for deep venous thrombosis.
