The target lesion was a severely tortuous and severely calcified lesion in the mid rca.Stenosis was 90%.The entire rca was pre-dilated.A 3.0x19mm non-medtronic stent was deployed prior to introducing the resolute onyx.It was reported that there was a dissection at the distal end of the non-medtronic stent.The non-medtronic stent was not post dilated to treat the dissection prior to the introduction of the resolute onyx.No resistance was encountered when advancing the resolute onyx through the previously deployed stent.However, when positioning and moving backwards, before inflation could be performed distally, close to the dissection, large resistance was encountered.The resolute onyx did not dislodge and was not deployed.The resolute onyx was removed from the patient just by pulling without the need for additional equipment.It was reported that two stents were hooked together, and the previously deployed non-medtronic stent was explanted from the patient with the resolute onyx.Another non-medtronic stent was then successfully implanted.It was previously reported that there was a detachment, but it has been confirmed that there was no break and no separation.If information is provided in the future, a supplemental report will be issued.
