A novel technique to remove a right atrial thrombotic mass attached to a patent foramen ovale (PFO) closure device.

Any percutaneously implanted foreign device carries the potential risk of thrombus formation. If a thrombus is detected after device implantation during follow-up, in most cases anticoagulation therapy is sufficient to resolve the thrombus. If the anticoagulation concept fails, surgery has been the only alternative option to remove thrombotic masses. This case of a patient with a large thrombus formation attached to a PFO closure device who denied surgery demonstrates that mechanical percutaneous clot retrieval is feasible with the AngioVac aspiration system (Vortex Medical, Inc., Norwell, MA). © 2013 Wiley Periodicals, Inc.
