This is filed to report that returned device analysis found that the hemostasis valve of the steerable guiding catheter (sgc) was torn, and if were to reoccur, has the potential to cause or contribute to patient injury.It was reported that this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 4+.There was a large jet located along the a2-p2 and a1-p1 scallop.The clip delivery system (cds) was advanced to the leaflets and the mr was reduced to 3+ with grasping.Deployment steps were started, but after the gripper line was retracted a few millimeters, it could not be properly removed.It was confirmed that the gripper line moved freely during the gripper line removability test.Troubleshooting maneuvers were performed without success.The cds was removed, leaving the gripper line in place.After removing the cds, the two ends of the gripper line were visible outside the hemostatic valve of the steerable guiding catheter (sgc).Another attempt was made to remove the gripper line, but was unsuccessful.The sgc was then removed, leaving the gripper line in place attached to the deployed clip.A new sgc was advanced and a second clip was deployed lateral to the first clip, reducing the mr to 1-2.The patient was confirmed to be stable post procedure.The sgc was returned, and it was found that the hemostasis valve was torn.No additional information was provided.
