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 per the physician is related to friable and tethered leaflets and is therefore, related to patient conditions.Unspecified tissue injury appears to be due to the slda.Tissue injury/damage is listed in the instructions for use (ifu) as a known possible complication associated with mitraclip procedures.Serious injury/ illness/ impairment was a result of case-specific circumstances.There is no indication of a product issue with respect to manufacture, design or labeling.

It was reported this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 4, restricted posterior, and thick leaflets.An xtw clip (31024a2072) was inserted, but upon closing the clip, a tear on the posterior leaflet was suspected.The clip was then repositioned and deployed.To further reduce mr, an additional xtw clip (31107r1082) was inserted and deployed.However, after deployment, the clip detached from posterior leaflet and remained attached to the anterior leaflet (single leaflet device attachment/slda).It was observed that there was damage to the posterior leaflet.Upon further review, the first clip had detached from the anterior leaflet and remained attached to the posterior leaflet (slda).No additional clips were implanted, and mr remained at a grade of 4.There was no clinically significant delay in the procedure.
