OPTImized coronary interventions eXplaIn the bEst cliNical outcomEs (OPTI-XIENCE) study. Rationale and study design.

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Medical Technology

Background:

• Clinical events can occur post-percutaneous coronary intervention (PCI), especially in complex cases.
• Intracoronary imaging and pressure guidewires can optimize PCI results and potentially reduce event risk.

Purpose of the Study:

• To test if unrestricted use of intracoronary tools for PCI optimization improves clinical outcomes in high-risk patients.
• To evaluate the effectiveness of advanced imaging techniques in complex coronary lesion interventions.

Main Methods:

• An observational, prospective, multicenter international study.
• 1064 patients received cobalt-chromium everolimus-eluting stents.
• Inclusion criteria focused on complex lesions and high-risk patient profiles; compared against a matched control group.

Main Results:

• The primary endpoint is the 1-year rate of target lesion failure (TLF).
• Secondary endpoints include mortality, myocardial infarction, target vessel revascularization, and stent thrombosis at 1 year.

Conclusions:

• The OPTI-XIENCE study aims to provide evidence for using intracoronary imaging in PCI.
• Findings will support the optimization of stent implantation in complex coronary lesions.
