Event Description
|
It was reported that on (b)(6) 2019, a 2.75x33mm xience pro stent was implanted in the mid left anterior descending (lad) coronary artery lesion.Post dilatation was performed and proximal stent malformation with stent malposition were observed.Reportedly, this was induced by the post-dilatation balloon.As treatment, additional balloon dilatation was performed, resolving the issue.There was no adverse patient sequela.No additional information was provided regarding this event.

Manufacturer Narrative
|
Internal file number - (b)(4).The xience proa is currently not commercially available in the u.S; however, it is similar to a device sold in the us.The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no similar incidents from this lot.The investigation was unable to determine a conclusive cause for the reported difficulty to deploy.The reported material deformation and device damaged by another appear to be related to circumstances of the procedure as it is likely the device interacted with the post-dilatation balloon causing the reported device damaged by another and subsequent material deformation.There is no indication of a product quality issue with respect to manufacture, design or labeling.

Event Description

Subsequent to the previous medwatch report, the additional information was obtained: following implantation of the 2.75x33mm xience pro stent, stent expansion was <90% in the distal half and malapposition was at the proximal edge.The operator decided to treat the distal half only.Following, the 3.0 non-compliant balloon possibly caused stent deformation at the proximal edge.The proximal malapposition was not treated.It was decided to treat the proximal stent portion in 4 weeks.On (b)(6) 2019, a 3.5x12mm xience proa stent was placed proximally.Post implantation, the stent expansion was at 92%.The maximum sized balloon at high pressure was used.
