Abstract

Clinical trial data suggest that intravascular ultrasound (IVUS) may improve clinical outcomes after PCI. The aim of this study was to investigate the safety of IVUS in its broader use for percutaneous coronary intervention (PCI). A total of 11,570 consecutive patients undergoing PCI between 2008 and 2014 in Japan were analyzed. Associations between IVUS use, PCI-related complications were assessed with logistic regression and propensity score matching analyses. Subgroup analysis was performed in elective PCI patients. IVUS was used in 84.8% of patients (N = 9814; IVUS group); its use was almost universal in elective PCIs (90.8 vs. 81.7% in urgent/emergent PCIs, P < 0.001). The non-IVUS group were older (68.7 ± 11.4 vs. 67.9 ± 10.8 years, P = 0.004), with more comorbid conditions. The non-IVUS group had smaller stent lumens (2.97 ± 0.42 mm vs. 3.09 ± 0.45 mm, P < 0.001) and a higher proportion of plain old balloon angioplasty. After matching, a lower rate of flow-impairing coronary dissections was observed in the IVUS group, although this was limited only to elective PCIs, not among urgent/emergent PCIs (non-IVUS vs. IVUS; 2.7% vs. 1.0%, P = 0.018, 0.7% vs. 1.2%, P = 0.32, respectively). With a multivariate logistic regression analysis, IVUS use remained an independent predictor to reduce risk of flow impairing severe coronary dissection among elective PCIs (odds ratio 0.38, 95% confidence interval 0.22–0.66: P = 0.001). In this Japanese PCI registry, IVUS was used extensively during the study period, particularly in elective cases. Using IVUS was associated with a lower event rate of flow-impairing coronary dissections that was limited to elective PCIs, not among urgent/emergent PCIs, without increasing PCI-related complications.
