[Thrombus formation in the locking wire of a Nit Occlud PFO device. Advantage of the “reverse reconfiguration” of the left atrial disc].

We describe the case of a 42-year-old female patient who suffered a cryptogenic ischemic stroke associated with a patent foramen ovale (PFO). During occlusion treatment with PFO devices, a thrombus was identified in the delivery system distal to the left atrial disc. Based on the reverse reconfiguration design, in which the left disc folds around its center, the device was recaptured, absorbing the thrombus protected by the folded disc, preventing embolization.
