This is filed to report clip movement and single leaflet device attachment (slda).It was reported that this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 4.The first mitraclip delivery system (cds) was successfully implanted medial.A second cds was advanced to the mitral valve, however, when going from the left atrium to the left ventricle, the clip got caught in the chordae, troubleshooting maneuvers were performed to free the clip from the chordae and the leaflets were successfully grasped.During clip deployment, when the clip released from the mandrel, there was tension on the clip, resulting in partial clip movement but the clip remained on both leaflets.Mr was reduced to 2-3.Fifteen minutes after clip deployment of the second clip, it was noted that the second clip detached from the posterior leaflet, and remained attached to the anterior leaflet (slda).Mr increased to 3-4.A third clip was implanted to further reduce mr and to stabilize the second clip; reducing mr to 2.The patient is stable.There were no adverse patient effects and there was no clinically significant delay in the procedure.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 partial clip movement, single leaflet device attachment (slda) and physical resistance appear to be related to user technique/procedural circumstances.Based on the information reviewed, there is no indication of a product quality issue with respect to design, manufacturing, or labeling of the device.
