ABSTRACT


There are conflicting data regarding the benefit of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) over angiography-guided PCI. Since the last meta-analysis was published, several new studies have been reported. We performed a comprehensive meta-analysis to evaluate the clinical impact of IVUS-guided PCI with drug-elutingstent compared with conventional angiography-guided PCI. This meta-analysis included 26,503 patients from 3 randomized and 14observationalstudies; 12,499 patients underwent IVUS-guided PCI and 14,004 underwent angiography-guided PCI. Main outcome measures were total mortality, myocardial infarction (MI), stent thrombosis, and target lesion revascularization (TLR). IVUS-guided PCI was significantly associated with more stents, longer stents, and larger stents. Regarding clinical outcomes, IVUS-guided PCI was associated with a significantly lower risk of TLR (odds ratio [OR] 0.81, 95% confidence interval [CI] 0.66 to 1.00, p=0.046). In addition, the risk of death (OR 0.61, 95% CI 0.48 to 0.79, p<0.001), MI (OR 0.57, 95% CI 0.44 to 0.75, p<0.001), and stent thrombosis (OR 0.59, 95% CI 0.47 to 0.75, p<0.001) were also decreased. In conclusion, our meta-analysis demonstrated that IVUS-guided PCI was associated with lower risk of death, MI, TLR, and stent thrombosis after drug-eluting stenti mplantation.
