Event or Problem Description
It was reported that on (b)(6) 2026, a patient presented with degenerative mitral regurgitation (mr), myxomatous posterior leaflet 2, wide prolapse of more than 15mm and flail gap of 10mm for a mitraclip procedure.During the procedure, first mitraclip was implanted.During implantation of second mitraclip, first grasp was difficult and there was interaction with chords.Second mitraclip was placed on the central side of anterior and posterior leaflet 2 (a2p2), as there was no change in the mr, the clip was moved to the medial side of the first clip and there was no significant mr reduction.It was decided to move closer to the first clip, grasping was obtained without significant mr reduction and increase in the gradient to above 6 mmhg.It was decided to invert the clip and come into the left atrium.Clip was closed and was moved lateral to the first clip.First clip appeared to be stable from the initial release.Paralax was removed from the second clip to match the first clip.Second clip was opened and it was determined that the clip interacted with the posterior mitral leaflet and the flail segment.Clip was inverted and retracted.Clip was initially thought to be freed from the interaction with the leaflet.On closing the clip, it was observed that there was motion in the first clip.On echo, it was determined that the first clip had single leaflet device attachment (slda) has occurred and clip was no longer attached to the posterior leaflet.Second clip was inverted and retracted into the left atrium released the interaction and the clip was removed from the patient.Procedure was discontinued.The final mr was grade 4.There were no adverse patient effects or clinically significant delays reported.
Additional Manufacturer Narrative
The device was not returned for analysis.A review of the lot history record revealed no manufacturing nonconformities issued to the reported lot that would have contributed to the reported incomplete coaptation, device damaged by another device, or poor imaging.Additionally, a review of the complaint history identified no similar complaints reported from this lot.Based on available information, the reported incomplete coaptation and device damaged by another device appear to be related to procedural conditions (interaction between another clip and posterior leaflet).The reported mitral regurgitation is a cascading event of the incomplete coaptation.The reported poor imaging is related to procedural conditions (shadowing due to sgc).The reported patient effect of mitral regurgitation, as listed in the mitraclip system instructions for use, is a known possible complication associated with mitraclip procedures.The reported hospitalization was a result of case-specific circumstances.There is no indication of a product quality issue with respect to manufacture, design, or labeling.Codes removed: medical device problem code.
