The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities that would have contributed to the reported event that would have contributed to the reported event.Additionally, a review of the complaint history did not indicate a lot-specific product issue.All available information was investigated, and the difficult or delayed positioning associated with leaflet grasping and capture per the account is due to dense subvalvular structures, short, restricted leaflet, shadowing over clip and leaflet, and is therefore relate to patient conditions and procedural conditions.The reported device damaged by another device (caused damage) appears to be related to procedural conditions, and due to this second clip interacting with the first implanted clip, causing slda of the first implanted clip.A cause for difficult or delayed positioning with anatomy, however, could not be determined.There is no indication of a product issue with respect to manufacture, design or labeling.

It was reported that on (b)(6) 2024, a mitraclip procedure was performed to treat mitral regurgitation (mr) grade x.Imaging was challenging due to patient anatomy.A ntw was implanted first successfully, although insertion was difficult due to the restricted posterior leaflet.A second ntw clip was then attempted to be implanted.During manuevering, this second clip interacted with the first clip eventually causing the first ntw clip to detach from the posterior leaflet (single leaflet device attachment (slda)).The second ntw was then placed to stabilize the slda.To further reduce mr, a third nt clip was implanted reducing mr to grade 2.There were no patient effects.The patient is reported to be stable.
