It was reported this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 4 and a restricted posterior leaflet.An xtw clip was prepared per the instructions for use (ifu) and inserted without issues.However, while positioning the clip, the anterior gripper became caught on the anterior leaflet.Troubleshooting was performed and the clip was removed from the leaflet without causing damage.It was then observed the gripper no longer lowered.Therefore, the clip was removed and replaced.One clip was then deployed, reducing mr to a grade of 1.There were no adverse patient effects and no clinically significant delay in the procedure.

All information was investigated, and the returned device analysis confirmed the reported single gripper actuation issue.Additionally, it was noted that the gripper line was broken.The reported difficult or delayed positioning anatomy could not be replicated in a testing environment.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 identified no similar complaints from the lot.All available information was investigated, and while the reported single gripper actuation issue appears to be related to the observed gripper line break, a cause for how the gripper line broke could not be determined.Additionally, a cause for the reported difficult or delayed positioning associated with the clip interacting with the anatomy cannot be determined.There is no indication of a product issue with respect to manufacture, design or labeling.
