Abstract
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 1 month, clinical outcomeswere similar between the two groups. At 6 months, 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 12 months, 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.
