Event Description
|
It was reported that stent fracture occurred: a percutaneous coronary intervention was being performed on a 75% stenosed ostial lesion in the proximal left circumflex coronary artery.The lesion was predilated with several balloons, including a non-boston scientific 1.5x15mm balloon at 16atm for 7 seconds, then an apex quantum 2.5x12mm at 22atm for 7 seconds, and then an apex quantum 3.0x20mm at 20 atm for 7 seconds.After this the 12x3.50mm promus premier select drug-eluting stent was implanted at 16atm for 5 seconds.After implantation the stent seemed to be fractured.The stent was post dilated with the apex quantum 2.5x15mm at 12 atm for 9 seconds, then the apex 3.0x15mm at 18 atm for 10 seconds and finally with an apex quantum 3.5x8 mm at 22 atm for 5 seconds.A second 3.5x8mm promus premier select drug-eluting stent was implanted in the fractured stent area.There were no adverse patient effects and the patient was stable.

Manufacturer Narrative

A2 - age at time of event: 18 years or older a cd was received and reviewed which contained one series of angiographic images, dated (b)(6) 2020.A review of the media provided could not identify the alleged stent fracture however a gap which could indicate strut displacement was noted in the proximal stent region.The apparent strut displacement noted could have appeared to the physician as stent fracture however this was not the case as the displaced struts visible in the media review along with the constricted region most likely represent a conformation of the stent (allowed by the stent's 2 connector and 4-connector design) to the vessel anatomy by considering the presence of fibro-calcific lesions and provide the required scaffolding without any straightening of the vessel.
