Left atrial thrombus formation on a CardioSeal Septal Occlusion device in a patient with elevated factor VIII: resolution with medical therapy.
We describe a case of thrombus formation on the left atrial disc of a CardioSeal Septal Occlusion device 14 days after transcatheter closure of a patent foramen ovale in a patient with a history of multiple cryptogenic strokes. Work-up to rule out the presence of a hypercoagulable state prior to device closure demonstrated an elevated factor VIII level. Medical therapy with heparin and aspirin was initiated, with subsequent clot resolution.
