The 90% stenosed target lesion was located in the none calcified and non tortuous mid of left anterior descending artery.
Following stent implantation, a 2.

However, during expansion the physician found the front end of the catheter was broken, 40 cm from the hub but not completely fractured.
The device was completely removed in a normal manner and the procedure was successfully completed with a different device.
No patient complications were reported.
