Patient admitted with cp x few weeks and found to have st-elevated myocardial infarction stemi.The patient was taken to the catheterization lab for angiography and potential percutaneous intervention.During the procedure, coronary balloon, from nc trek coronary dilatation catheter, could not be removed from guide catheter during angioplasty/stent procedure.The body of the balloon telescoped inside itself and made a hard ridge that got stuck on guideliner making it impossible to be removed from guide catheter.As a result, the entire system had to be removed.Additional notes.Drug-eluting stent placed and post-dilated with a 4.0 x 15 mm nc trek balloon at high pressure.Health care providers were unable to pull the deflated balloon completely back into the guide, so the entire system was removed as one.The balloon then stuck as it was entering the radial sheath.The balloon was advanced over the wire a bit, inflated to very low pressure, and then successfully withdrawn as it was deflated.Inspection of the balloon revealed that the more distal edge that had failed to assume a lower profile.
