A quarter of patients with implanted cardiac devices have a patent foramen ovale (PFO). Thrombus is frequently noted on intravascular leads that in the presence of a PFO could result in cerebral vascular embolic events. However, whether thismechanism of stroke occurs is not clearly known. We report three patients with PFO, implanted leads with thrombus, and stroke, including a patient where thrombus partially attached to the lead was seen traversing the PFO.
