Saito Y, et al. - In this analysis of 393 coronary vessels which underwent percutaneous coronary intervention with stents, researchers examined the link between the difference in intraluminal intensity of blood speckle (IBS) on integrated backscatter-intravascular ultrasound (IB-IVUS) across the coronary artery stenosis (ΔIBS) and target vessel revascularization (TVR), given a reported negative correlation of ΔIBS with fractional flow reserve, which predicts TVR. They excluded vessels without IVUS-guidance and follow-up information. Intraluminal IBS values were determined. Findings revealed a significant correlation between ΔIBS post-procedure and TVR. Via physiological evaluation with measurement of ΔIBS, TVR may be predicted by IVUS.
