It was reported that the procedure was to treat a de novo, moderately calcified and heavily tortuous vessel in the left anterior descending (lad) artery.
The 4.
0x28mm xience prime stent delivery system (sds) balloon was inflated once at 10 atmospheres (atms) with a contrast mix of 1:1 heparinized normal saline and the stent was deployed, however, the balloon completely failed to deflate post implantation even after negative was held for 5 seconds.
The balloon was withdrawn inflated and there was resistance with the anatomy during removal.
Force was applied during removal and after several attempts, the balloon was pulled along with the guiding catheter.
No additional intervention was required, the catheter was removed together with guiding catheter that was already present in the anatomy.
There was no adverse patient effect and there was no clinically significant delay in the procedure.
No additional information was provided.
