Event or Problem Description
An attempt was made to use one telescope guide extension catheter and one onyx frontier coronary drug eluting stent to treat a moderately tortuous, severely calcified lesion with 90% stenosis in the mid right coronary artery (rca).The vessel tortuosity and calcification made it difficult for passage of equipment.Both devices were inspected with no issues noted.The telescope was prepped per ifu with no issues.Negative prep was performed on the onyx frontier with no issues.The lesion was not pre-dilated.The onyx frontier did not pass through a previously deployed stent.Resistance was encountered when advancing both devices.Excessive force was not used.It was reported that there was damage to the tip of the telescope device, and stent dislodgement occurred during delivery to the lesion.The tip of the telescope tip was torn.The stent snagged on the tip of the telescope catheter and came off the delivery system.After removing the telescope device, the stent was able to be retrieved by using a smaller platform.All devices were retrieved eventually with no adverse effects on the patient.The patient is alive with no further injury.
