Event Description

An attempt was made to use one onyx trustar coronary drug eluting stent (des) to treat a severely tortuous, moderately calcified lesion in the left main (lm) artery.The device was inspected with issues noted.The device did not pass through a previously deployed stent.Resistance was encountered when advancing the device.Excessive force was not used during delivery.It was reported that stent deformation occurred in vivo during positioning/advancement.It was detailed that the onyx trustar des was more curved than usual following inspection.When attempting implantation, the stent could not pass due to calcification which caused damaged to the stent strut.The procedure was completed with a new 2.5x26mm onyx trustar des.The patient is alive with no injury.Please note that this device (onyx trustar) is not marketed in the united states; however, the device is deemed the same as the united states marketed device (onyx frontier).
