Event Description
|
It was reported that on (b)(6) 2024, a mitaclip procedure was performed to treat degenerative mitral regurgitation (mr).A mitral xtw (lot: ) was chosen for implantation.Three grasp attempts were performed but posterior leaflet could not be grasped or captured.Mr rose slightly, thought to be due to leaflet damage.Clip was placed in a new location successfully, reducing mr to grade 2.A ntw mitraclip (lot: 30814r3057) was then implanted lateral to the first clip.After deployment the ntw detached from the posterior leaflet but was stable on anterior leaflet.Third clip was not attempted to be implanted due to the weakness of the leaflet.After five minuties the ntw clip also detached from the anterior leaflet and embolized into the lower left pulmonary vein.A snare was advanced through the steerable guide catheter (sgc) and the clip was snared to the tip of sgc.The sgc was then pulled back to the right atrium but the clip then became stuck in the intra-atrial septum.The clip was stable at this position so it was decided to deploy.There was reportedly a clinically significant delay.Patient was reported to be stable.

Manufacturer Narrative

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 based on the information reviewed, a cause for the reported slda and ultimately expulsion (clip detaching from both the leaflets) cannot be determined.Entrapment of device appears to be related to procedural conditions and due to the way the embolized clip was being removed from the anatomy.Image resolution poor was related to procedural conditions of suboptimal imaging.Embolism and foreign body in patient appear to be related the complete clip detachment (expulsion).Unspecified tissue injury to the septal area appears to be related to procedural conditions associated with the way the clip was being removed from the anatomy.Embolism and tissue damage are listed in the instructions for use (ifu) as known possible complications associated with mitraclip procedures.Unexpected medical intervention and delay to treatment / therapy were a result of case-specific circumstances.There is no indication of a product issue with respect to manufacture, design or labeling.
