It was reported that using a brachial artery access approach during a procedure of the eccentric, 70% restenosed, non-tortuous, proximal left anterior descending (lad) artery predilatation with a 5.0 x 10 mm non-abbott balloon dilatation catheter (bdc) was completed at 6 atmosphere (atm) for 6 seconds and inflated again.The bdc was removed and the 4.0 x 18 mm xience prime stent was deployed at 14 atm for 30 seconds.It was noted that post-dilatation was completed using a 5.0 x 15 mm nc trek bdc at 12 atm and 16 atm but after deflation the bdc met resistance while attempting to be removed.The bdc was inflated and deflated twice and was removed with resistance.Although the indeflator was not on negative pressure, after removal from the anatomy the balloon was noted to be winged.Additionally, the bdc shaft was noted to have separated during removal.There was no reported adverse patient effect.There was no reported clinically significant delay in the procedure.No additional information was provided.
