Event or Problem Description
One resolute onyx coronary drug eluting stent was attempted to be used to treat a moderately tortuous, severely calcified lesion with 80% stenosis in the mid circumflex (cx) - obtuse marginal (om) artery.The device was inspected prior to use with no issues noted.Negative prep was performed with no issues noted.The lesion was pre-dilated.The device did not pass through a previously deployed stent.Resistance was encountered when advancing the device.It was reported that the stent failed to cross the lesion and when the stent catheter was removed it was noted that the stent had dislodged.The stent was observed to be in the left main (lm).An attempt was made to remove the stent using a snare but was unsuccessful.The lm was then stented with another stent in order to crush the dislodged stent in the lm.No further patient injury reported.
