It was reported that the procedure was performed to treat an 80% stenosed, heavily tortuous, and heavily calcified lesion in the right coronary artery.
Following pre-dilatation, a 3.
5x33mm xience sierra stent was deployed without issues.
A 4.
0x15mm nc trek balloon dilatation catheter (bdc) was used to post-dilate the stent at nominal pressure; however, the balloon would not deflate.
An attempt to deflate the balloon with a second indeflator was made, but this too failed.
The balloon was inflated to 20 atmospheres and a non-abbott guide wire was advanced and ruptured the balloon.
The bdc was able to be retrieved.
There were no adverse patient sequela and no clinically significant delay in the procedure.
No additional information was provided.
