It was reported that the procedure performed was to treat a de novo, heavily calcified, moderately tortuous left anterior descending coronary artery that is 99% stenosed.The 190cm 014 ht versaturn guidewire was entrapped in the calcified lesion making it difficult to remove; however, was withdrawn with force.Upon removal, the tip of the guidewire was noted to be spiral-shaped/wavy and could not be re-shaped.A new versaturn guidewire was used to complete the procedure.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
