Event Description

It was reported that on (b)(6) 2023, a mitraclip procedure was performed to treat degenerative mitral regurgitation (mr) with grade 4, with a large posterior mitral leaflet flail.A mitraclip xtw (30801r1039) was advanced to the mitral valve but became caught in chordae.While attempting to remove the clip, the chordae appeared to be damaged.The clip was implanted with a good central tissue bridge and deployed on both leaflets.However, a large flail was still visible.The flail had worsened as it had appeared that the papillary muscle, which was part of the flail, was damaged.A mitraclip xtw (30620r1070) was then advanced to mitral valve and implanted.The procedure was completed with two clips implanted.The clips were stable on the leaflets.The mr remained at grade 4.On (b)(6) 2023, one day post procedure, the patient died due to being hemodynamically unstable.The patient had very low blood pressure.In the physician's opinion, the mitraclips did not cause or contribute to the patient death, but the pre-existing mr, which could not be improved, caused or contributed to the patient's death.The documented cause of death was due to multi organ failure due to septic and cardiogenic shock despite a non-abbott heart pump treatment.No additional information was provided.

Manufacturer Narrative

Investigation is not yet complete.A follow-up report will be submitted with all additional relevant information.

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 this event.The investigation determined the reported unchanged mr appears to be related to patient conditions in conjunction with the tissue injury.The reported multiple organ dysfunction syndrome and cardiogenic shock appear to be related to pre-existing patient conditions.The reported hypotension, hypoxia, arrhythmia, and subsequent death appear to be due to multiple organ dysfunction syndrome and cardiogenic shock.Mr, multiple organ dysfunction syndrome, hypotension, cardiogenic shock, hypoxia, arrhythmia, and death are listed in the instructions for use as known possible complications associated with mitraclip procedures.The reported unexpected medical interventions were results of case specific circumstances as an additional clip was implanted due to the unchanged mr and a non-abbott heart pump was used for treatment.There is no indication of a product issue with respect to manufacture, design or labeling.H6: code 2072 removed.
