This is filed to report the large atrial septal defect (asd).It was reported that this was a mitraclip procedure to treat degenerative mitral regurgitation (mr) with a grade of 4+.During the procedure, the steerable guide catheter (sgc) slipped from the left atrium (la) to the right atrium (ra) two times.The sgc was re-advanced to the la without issue.Three clips were implanted, reducing the mr to 2.After the sgc was removed, a large atrial septal defect was noted, which was treated with an asd occluder.The patient had a good outcome.No additional information was provided.

(b)(4).The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot.Additionally, a review of the complaint history identified no other incidents reported from this lot.The reported patient effect of atrial septal defect (asd), as listed in the mitraclip system instructions for use, is a known possible complication associated with mitraclip procedures.All available information was investigated and the reported steerable guide catheter (sgc) slipping back into the right atrium (ra) appears to be related to user technique, as the device was inadvertently moved.The reported patient effect of asd is likely procedurally related, as the sgc is advanced through the septum in order to gain access to the left atrium (la) for positioning over the valve.There is no indication of a product quality issue with respect to manufacture, design or labeling.
