It was reported that the procedure was to treat a moderately tortuous, moderately calcified, and chronic total occlusion (cto) in the mid left anterior descending artery (lad).
An unspecified guide catheter was advanced though the radial access and a 4.
0x15mm nc trek rx balloon dilatation catheter (bdc) was used to post-dilate an unspecified deployed stent to 24 atmospheres.
An attempt to remove a non-abbott guide wire and the bdc was made; however, the bdc could not be removed due to resistance with the anatomy and the non-abbott guide wire.
An attempt to pull out the bdc with a larger sheath was made, but unsuccessful.
The bdc could not be retrieved from the patient from the radial part of the artery directly after finishing the procedure.
The patient was discharged for vascular surgery; however, it could not be confirmed if the device was removed.
A clinically significant delay was reported.
No additional information was provided.
