Abstract/OtherAbstract:
INTRODUCTION: The gold standard for evaluating stent expansion after percutaneous coronary intervention (PCI) is intravascular ultrasound (IVUS). However, the routine use of this modality is costly and time consuming. StentBoost is a new imaging technique that improves fluoroscopy-based assessments of stent expansion. The purpose of this study was to evaluate the effect of StentBoost imaging-guided PCI on mid-term angiographic and clinical outcomes. METHODS AND RESULTS: A total of 870 consecutive patients were recruited (mean age: 64.34±11.61; men: 64.5%), all of whom underwent PCI with drug-eluting stents (DESs). The subjects were divided into a no StentBoost group (n=569 patients) and a StentBoost group (n=301 patients). The 6-month angiographic and 12-month clinical outcomes were compared between the two groups. At 1month, clinical outcomes were similar between the two groups. At 6months, the StentBoost group had significantly lower rates of late loss (0.32±0.40 vs. 0.48±0.59; p=0.005) and binary restenosis (1.2% vs. 8.3%; p=0.029) compared with the no-StentBoost group. At 12months, StentBoost group had significantly lower the incidence of target lesion revascularization (TLR) (1.7% vs. 7%; p=0.034) and TLR-major adverse cardiac events (6% vs. 13.2%; p=0.037) compared with the no-StentBoost group. CONCLUSION: We conclude that the routine clinical use of StentBoost during PCI can be useful, and results in better medium-term angiographic and clinical outcomes.
