Turnpike spiral broke during procedure.Additional information received 18apr19: pt returns for high risk pci of complex, calcified, diffusely diseased rca.A 8f guide was advanced to the rca ostium from the right femoral artery and a balloon-tipped pacing wire was advanced to the rv apex from the right femoral vein.The complex mid lesion was crossed with a guidewire (after attempting with a previous wire) but a turnpike spiral would not cross despite support of a 8f trapliner.Decision made to withdraw the trapliner and balloon the proximal vessel to allow for more distal placement of the guideliner.Upon withdrawal of the turnpike spiral, the tip of the catheter fractured in the lesion.The remainder of the catheter was withdrawn.Next, limited attempts made to wire the vessel with another guidewire was unsuccessful, but the proximal disease was ballooned with a 3.0x15mm nc balloon and upon withdrawal of the balloon, the dislodged catheter tip was dragged back into the guideliner.Decision made to trap the catheter tip in the guideliner with a 2.Omm balloon and withdraw everything through the guide., access had been obtained in the contralateral groin to allow for visualization of the distal vessel during attempts to rewire the vessel.Decision made to attempt retrograde crossing of the now occluded, collateralized rca.The distal rca could not be accessed despite attempts through the first and second septal branches.Dissection-re-entry not attempted due to high proximal takeoff of rpda.Ultimately, decision made to make a final attempt at rewiring the vessel antegrade, which was successful with a htf wire.The lesion was ballooned with a 1.0mm balloon which ruptured.After advancing guideliner distally over the 3.0mm balloon, a turnpike spiral was successful in crossing distally and the wire exchanged for a floppy wire.Rotational atherectomy performed with a 1.5mm burr followed by pre-dilatation of the vessel with a 2.5x40mm balloon., the vessel was stented with overlapping 3.5x38mm des x 2, extending back to the vessel ostium.The stented segment was post dilated with a 4.0x30mm nc balloon.The mid stented segment was further post dilated with a 4.5x1smm nc balloon.The patient tolerated this prolonged procedure well with the help of anesthesia administering conscious sedations.Adjunctive heparin was used.Both arterial sites were closed.

A manufacturing record review was completed and no related nonconformance's were found associated to the reported event, therefore supporting the device met material, assembly and performance specifications.A returned product evaluation was also completed.The distal tip was twisted and about 1mm of tip material was missing.The distal shaft of the turnpike catheter was wavy.The distal coil was fully bonded to the catheter and was not damaged.The shaft and tip damage are consistent with torquing the catheter in a calcified lesion.
