The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot.Based on the information reviewed, a definitive cause for the reported thrombosis and embolism could not be determined in this event.The reported patient effects of embolism and thrombus as listed in the mitraclip system instructions for use are a known possible complication associated with mitraclip procedures.Although a conclusive cause for the reported patient effects and the relationship to the device, if any, cannot be determined, there is no indication of a product quality issue with respect to manufacture, design or labeling.

This is being filed to report thrombosis and medical intervention.It was reported that this was a mitraclip procedure to treat mixed mitral regurgitation (mr) with a grade of 4+.A steerable guide catheter (sgc) was advanced to the mitral valve, and the first clip was deployed, reducing mr.Then when inserting the second clip delivery system (cds), a clot was observed on the sgc, in the left and right atrium.The cds was removed and aspirations were performed.The patient was given medication.Then when the sgc was removed, the thrombus was gone.It was suspected that the thrombus embolized, but this could not be confirmed.The procedure was aborted.The patient is stable.One clip was implanted, reducing mr to 2-3.There were no adverse patient effects and no clinically significant delay in the procedure.
