It was reported that removal difficulties were encountered.Vascular access was obtained via radial artery.A 90% stenosed, eccentric, de novo target lesion containing >45 and <90 degrees bend was located in the moderately tortuous and moderately calcified mid right coronary artery (rca).An unknown drug-eluting stent (des) was implanted in the proximal rca.After using a non- boston scientific (bsc) guide catheter, a non-bsc guide wire was advanced to the distal rca.Subsequently, a 28x3.50mm promus premier select des was advanced to treat the lesion in the mid rca.However, the device was caught in plaque distal to proximal des.Several attempts were conducted to pull out the device but was unsuccessful.The device was inflated and was implanted at the site where it can not be moved forward or backward.A non-bsc stent was advanced to the mid rca and was successfully implanted.The procedure was completed with no patient complications reported.The patient status was stable.
