This is being filed to report the septal dissection.
It was reported that this was a mitraclip procedure to treat functional mitral regurgitation (mr) with a grade of 4.
One clip was implanted, reducing mr to 1.
After withdrawing the steerable guide catheter (sgc) from the left atrium, a septal dissection was noted.
There was significant shunting of blood trough the atrial septal defect (asd).
The patients blood pressure was stable and the dissection did not grow therefore no treatment was performed.
There was no clinically significant delay in the procedure and no adverse patient sequela.
No additional information was provided.

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.
Based on available information, a cause for the reported perforation could not be determined.
However, the reported patient effect of perforation as listed in the mitraclip instructions for use (ifu), is known possible complication associated with mitraclip procedures.
There is no indication of a product issue with respect to manufacture, design or labeling.
