It was reported that the procedure was performed to treat a 99% stenosed and moderately tortuous lesion in the left main artery to the mid left anterior descending artery (lad).
Following pre-dilatation, st elevation was noted.
Aspiration was performed with a thrombectomy device and medication was administered.
The st elevation was still slightly noted.
Three xience sierra stents (2.
25x38mm, 3.
0x38mm, and 3.
5x23mm) were deployed in the mid lad to the left main artery from the distal side.
Proximal optimization technique was also performed in the mid lad and proximal lad with 3.
25mm non-abbott balloon catheter.
For kissing balloon technique of the lad artery and the 1st diagonal artery, a 2.
5x8mm nc trek balloon dilatation catheter (bdc) was chosen.
The bdc was prepared; however, the stylet was not removed before prep.
Additionally, resistance was noted when removing the stylet from the bdc.
An attempt was made to insert the bdc onto a non-abbott guide wire; however, the bdc failed to be inserted onto the guide wire.
It was thought that the lumen of the bdc collapsed during removal of the stylet.
The bdc was not used and the procedure was successfully completed with a 2.
5x6mm non-abbott balloon catheter.
There were no adverse patient effects and no clinically significant delay in the procedure.
No additional information was provided.
