It was reported that during a procedure to treat a de novo lesion in the left anterior descending artery with 70% stenosis, a 2.5x15 mm rx xience v stent delivery system (sds) was advanced and deployed.The stent was well apposed; however, the balloon was difficult to deflate and the deflation time was long.While the sds was being withdrawn, resistance was felt with the non-abbott guiding catheter.The sds was finally able to be withdrawn with the balloon deflated in the guiding catheter; however, the balloon refold was poor.Additionally, a 2.5x8 mm rx xience v sds was implanted during the procedure without issue.There was no adverse patient effect and no reported clinically significant delay in the procedure.No additional information was provided.
