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 the reported event.Additionally, a review of the complaint history identified no similar complaints from the lot.Based on information provided and without the device to analyze, a cause for the reported leak/splash (loss of fluid column during device preparation) and thrombosis/thrombus could not be determined.However, thrombus is a known possible complication associated with mitraclip procedures.Medication required 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 that a mitraclip procedure was performed to treat a functional mitral regurgitation (mr) with grade of 4.After the steerable guide catheter (sgc) crossed the septum to the left atrium, a clot was observed on the tip of the guide.Activated clotting time (act) was noted to be over 300 at the time the clot was observed.The patient was given an increased dose of heparin.The sgc was removed.After removal, the sgc was heparinized, cleaned, and re-flushed/prepared.However, during the second preparation, it was noted that the sgc could not hold fluid column.It was decided to use a replacement sgc to complete the procedure.One clip was implanted, reducing mr to grade <1.There was no clinically significant delay in the procedure and no adverse patient effects.
