This is filed to report difficult to remove and tissue damage.It was reported that this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 4+.It was noted enlarged atrium and ventricle.The first clip delivery system (cds 00305u117) was advanced to the mitral valve, and the clip was deployed, reducing mr.Then a second cds (00603u189) was advanced to further reduce mr.However, during an attempt to grasp, the leaflets became entangled with the grippers.Using maneuvers to free the clip, the clip was then inverted and retracted back into the left atrium.The clip was then advanced into the left ventricle and grasping was performed.However, a sudden big jet was observed and a possible lesion between the a1-a2 scallops was detected.A decision was made to remove the cds with the clip attached.One clip was implanted, and mr is 4+.There was no clinically significant delay in the procedure.No additional information was provided.
