Event Description

This is filed to report a patient death.It was reported that on (b)(6) 2023, a mitraclip procedure was performed to treat functional mitral regurgitation (mr) with grade 4+ and enlarged atrium.During steerable guide catheter (sgc) insertion, a loose connection between the stabilizer and the steerable guide catheter (sgc) occurred.The plastic sgc handle was rotating independently.When rotating the plastic handle, the sgc shaft rotated as well, but at a different speed, and not synchronized.The stabilizer was exchanged for another to continue with the procedure.To ensure stability, the physician held the plastic handle to the sgc throughout the procedure.A mitraclip ntr was implanted on a2/p2 and the mr decreased to grade 2+.The final angle of the first clip was approximately 20 degrees.A second clip mitraclip ntr was prepared and while establishing final arm angle (efaa) the first time, the clip opened to about ten degrees.The second time the efaa worked.The clip was implanted 2mm from the first clip and the mr decreased to grade 1+.The final angle of the second clip was approximately 20 degrees.The procedure was completed with two clips implanted.The mr was reduced to grade 1+.There was no clinically significant delay in the procedure.Following the procedure, during patient monitoring, the mr had increased to grade 4+, the patient had no improvement, with symptoms of fatigue, dyspnea, limb edema, and shortage of liberties.On (b)(6) 2023, the patient passed away due to aggravated heart failure.In the physician¿s opinion the patient death was related to the implanted clips.Echo imaging revealed that clip distance between clip apexes changed from 2mm to 4mm between the two mitraclips.The clip apexes had shifted apart from each other.The documented cause of death was due to multiple organ dysfunction syndrome (mods) and worsening heart failure.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.Additionally, a review of the complaint history identified no similar complaints reported from this lot.The investigation was unable to determine a cause for the reported unintended movement of clip open while establishing final arm angle (efaa) and migration.The reported recurrent mitral regurgitation (mr) and subsequent heart failure appear to be related to the reported clip migration.Death appears to be related to acute chronic chf.Death, heart failure and mr are listed in the instructions for use (ifu) as known possible complications associated with the mitraclip procedures.There is no indication of a product issue with respect to manufacture, design, or labeling.H6: codes 1816, 1849, and 4577 removed.
