Zijing Liu , MD;

Dan Niu , MD;

Jincheng Guo , MD;

A novel technique was used to eliminate the guidewire shadow artifact by removing the guidewire in frequent domain optical coherence tomography interpretation in vivo. This technique allowed us to observe a rare iatrogenic spiral dissection...

Daniel Obaid , MBBCh, PhD;

Alexander J. Chase , MBBCh, PhD, MBBS, MD;

Dave Smith , BM, MD;

3D-OCT revealed extensive fracture and distortion of the struts in the distal portion of a stent, presumably caused by aggressive postdilation at the time of implantation. This was managed successfully with the insertion of a new coronary...
