Event or Problem Description

It was reported that the procedure was to treat a moderately calcified, 80-99% stenosed lesion in the mid anterior interventricular artery (iva).A 2.5x20mm trek rx balloon dilatation catheter (bdc) was advanced to the target lesion for pre-dilatation.The initial inflation was to 14 atmospheres (atm) and held for 14 seconds.The bdc was then moved a few millimeters to pre-dilatate a more proximal part of the lesion when resistance was noted.The second inflation was to 20 atm and held for 10 seconds.Subsequently, imaging was performed, and it was noted that the balloon only partially deflated.The balloon was able to be successfully removed from the anatomy while it was partially inflated.There was no adverse patient effect and no clinically significant delay in the procedure.

Additional Manufacturer Narrative

H6 medical device problem code 2017 clarifier above rbp.Visual, dimensional and functional inspections were performed on the returned device.The reported deflation issue could not be confirmed as the device deflated without issue, per manufacturing specifications.The reported difficulty advancing the device could not be replicated in a testing environment as it was based on operational circumstances.A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.Additionally, a review of the complaint history identified no other similar incidents/complaints from this lot.It was reported that during the second inflation, the bdc was overinflated to 20 atmospheres (atms).It should be noted that the coronary dilatation catheters (cdc), trek rx global, instruction for use (ifu) states: balloon pressure should not exceed the rated burst pressure (rbp).The rbp for the trek rx device is 14 atm; therefore, rbp was exceeded.In this case, it is unknown if the violation caused or contributed to the reported complaint.The investigation was unable to determine a conclusive cause for the reported deflation issue; however, the reported difficulty advancing the device appears to be related to circumstances of the procedure.There is no indication of a product quality issue with respect to design, manufacture or labeling of the device.

Subsequent to the initial report, the following information was received: after the initial inflation, the bdc was not fully deflated, but was moved a few millimeters to pre-dilatate a more proximal part of the lesion when resistance was noted.No additional information was provided.
