This is filed to report the single leaflet device attachment (slda).It was reported that this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 3.The first clip delivery system (cds)(70629u143) was advanced to the mitral valve and after several attempts to grasp the leaflets, the clip was deployed.The mr was reduced to 2.While preparing the second cds(70629u145), it was noted the first clip detached from the posterior leaflet and remained attached to the anterior leaflet (slda).The mr returned to 3.The second clip was implanted medial of the first implanted clip to treat the mr and stabilize the first clip, reducing the mr to 2.A third clip was implanted lateral, reducing the mr to 1.The patient left cath lab stable.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 that would have contributed to the reported event.Additionally, a review of the complaint history did not indicate a lot-specific quality issue.All available information was investigated and the reported failure to adhere/ bond (difficult grasping the leaflet) and single leaflet device attachment (slda) in this incident appears to be related to patient morphology/challenging anatomy (pre- existing thin posterior mitral leaflet).The reported poor image resolution is related to the difficulty in visualization during the procedure as it was not possible to show both leaflets on the clip arms at one time.It was needed to rotate the echo probe to show them one by one.There is no indication of a product quality issue with respect to manufacture, design or labeling.
