At catheterization the mid right coronary artery was found to have a 100% calcified, thrombotic occlusion.Successful intervention with serial dilatation and mechanical thrombectomy resulted in thrombolysis in myocardial infarction (timi)-3 flow.An attempt was then made to advance a drug-eluting stent.However, the stent appeared to be stripping off the balloon within the proximal right coronary artery.When an attempt was made to retract the stent into the guide catheter, it became crimped against the edge of the guide catheter opening.While attempting to remove the coronary guide catheter and stent with balloon system as a unit, the stent stripped off the balloon within the radial artery distal to the elbow joint.
