Event Description
During a procedure a resolute onyx rx coronary drug eluting stent was used to treat a high grade in-stent stenosis located in the ostium rca. The device was inspected with no issues noted. Negative prep was performed. The lesion was pre-dilated with a nc solarice, a non-medtronic balloon and a deb in. Pact falcon. After dilatation with the deb there was still a restenosis it was reported that inflation difficulties were encountered during stent deployment and that stent dislodgement occurred during deployment. At the beginning of deployment everything seemed normal but suddenly the stent dislodged. An attempt was made to locate the stent. It was first located in the arm but was unable to be retrieved. The stent was then located in the renal artery and any attempt to retrieve the stent failed. The stent was left in the renal artery. Patient is alive with no further injury reported.
Manufacturer Narrative
Image analysis summary: an image shows the rca with a previously deployed stent in the ostium. A balloon is delivered inside the previously deployed stent and inflated. Further dilations are performed. The next images show attempts to search around the body for a dislodged stent. There were no images showing the attempted delivery of this stent or the reported inflation difficulties encountered when deploying the stent. Attempts are made to retrieve the dislodged stent. The dislodged stent moves to the renal artery and is found under fluoroscopy. The final images show the dislodged stent in the renal artery. The dislodged stent was not removed. Product analysis summary: a kink was evident on the hypotube. The stent was not present on the balloon and did not return for analysis. The delivery system returned with blood visible in the balloon and inflation lumen. The balloon folds were partially expanded. Crimp impressions were visible on the exposed balloon surface. The delivery system was placed in the waterbath to disperse the blood and aid inflation. Upon removal, the balloon failed negative prep. On pressurisation of the delivery system, liquid was observed exiting the balloon distal cone. The balloon failed to maintain pressure. Upon visual inspection of the delivery system, there was a short longitudinal tear on the balloon material on the distal cone. Lead in scratches were not evident proximal or distal to the tear site. The balloon material was jagged and uneven at the tear site. The inner lumen patency was verified with a 0. 015 inch mandrel. There was no other damage evident to the remainder of the delivery system. If information is provided in the future, a supplemental report will be issued.
Manufacturer Narrative
High grade in-stent stenosis occurred in a previously implanted resolute integrity coronary drug eluting stent located in the ostium rca. No resistance was noted while advancing the resolute onyx device to the lesion. It was only possible to inflate the resolute onyx to approx 1-2 atm. The same inflation device was used for all devices that were used in this procedure, with no inflation difficulties noted. The physician assessed that the inflation difficulty was not due to vessel morphology, or the inflation pressure applied. If information is provided in the future, a supplemental report will be issued.
