Does OCT improve visualization of tissue prolapse between coronary stent struts compared to IVUS?
Does OCT improve visualization of tissue prolapse between coronary stent struts compared to IVUS?
OCT provides superior resolution compared to IVUS for visualizing detailed structures such as tissue prolapse between coronary stent struts.
Answers are grounded in this paper and cite their sources.
OCT may better detect post-stent tissue prolapse than IVUS; hypothesis-generating and should not change practice.
IVUS (A) and OCT (B) images of the stented right coronary artery are shown.Although IVUS showed a well-deployed stent, the detailed structure around the stent struts is not well visualized.In addition, OCT clearly visualized tissue prolapse between the stent struts (12 to 3 o'clock).The tissue prolapse occurred mainly in an area with lower OCT signal intensity, which is suggestive of a plaque with a large lipid content.
