It was reported that device entanglement occurred.The 75% stenosed target lesion was located in the moderately tortuous and moderately calcified mid left anterior descending artery (lad).A 1.25mm rotapro was selected for use.During procedure, the system was advanced over the wire where the revs were set outside the patient.Dynaglide mode was activated, the brake defeat button was pushed and secured with the wire-clip.When the system was advancing into the catheter it was noted that the end of the wire started to tangle due to the wire spinning rapidly.The wireclip was removed and clipped again, and the brake defeat button was pressed again.The system was removed and the vessel was treated with a balloon and stent.There were no patient complications reported.
