Key result
StentBoost demonstrated superior correlation with IVUS for measuring minimum stent diameter (r=0.75; P<0.0001) compared to QCA, and a diameter <2.5 mm predicted inadequate expansion.

Does StentBoost accurately detect inadequate coronary stent expansion compared to IVUS in patients undergoing stent implantation?
Effect estimate: r=0.75
p-value: p=<0.0001
StentBoost provides superior correlation with IVUS for measuring stent expansion compared to QCA, offering a potentially useful fluoroscopic tool for detecting inadequate stent deployment.
Mishell et al. (2006) conducted a cross-sectional in Coronary stent implantation (n=30). StentBoost vs. Intravascular ultrasound (IVUS) and quantitative coronary angiography (QCA) was evaluated on Correlation of minimum stent diameter between IVUS and StentBoost (r=0.75, p=<0.0001). StentBoost demonstrated superior correlation with IVUS for measuring minimum stent diameter (r=0.75; P<0.0001) compared to QCA, and a diameter <2.5 mm predicted inadequate expansion.
