It was reported that on (b)(6) 2024, a mitraclip procedure was performed to treat functional mitral regurgitation (mr) with a grade of 4, a restricted posterior leaflet, an enlarged atrium, and posterior cleft.It was noted imaging was challenging.One clip was implanted, reducing mr to a grade of 2.Shortly after the procedure, echocardiography showed the implanted clip had detached from the posterior leaflet and remained attached to the anterior leaflet (single leaflet device attachment/slda), causing mr to increase to a grade of 4.On (b)(6) 2024, an additional mitraclip was performed.One clip was implanted, stabilizing the slda and reducing mr to a grade of 2.

The device was not returned for analysis.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 the reported slda associated with clip detaching from the posterior leaflet per the account is related to patient conditions (thin leaflets).Image resolution poor is related to patient and procedural conditions associated with difficulties visualizing the clip due to shadow mostly due to anatomy.Mitral valve insufficiency/ regurgitation appears to be due to the slda.Mitral regurgitation is listed in the instructions for use (ifu) as a known possible complication associated with mitraclip procedures.Unexpected medical intervention and hospitalization were a result of case-specific circumstances.There is no indication of a product issue with respect to manufacture, design or labeling.
