Insights
Intravascular imaging significantly reduces major adverse cardiovascular events in multivessel coronary artery disease patients undergoing percutaneous coronary intervention. Both intravascular ultrasound and optical coherence tomography offer similar benefits over traditional angiography.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Imaging
Background:
- Percutaneous coronary intervention (PCI) for multivessel coronary artery disease presents challenges due to anatomical complexity and risks of adverse cardiovascular outcomes.
- Conventional angiography offers limited insights into vessel structure and plaque characteristics.
- Intravascular imaging modalities like intravascular ultrasound (IVUS) and optical coherence tomography (OCT) may enhance PCI procedural guidance, but their clinical impact is uncertain.
Purpose of the Study:
- To systematically evaluate the clinical impact of intravascular imaging-guided PCI versus angiography-guided PCI in patients with multivessel coronary artery disease.
- To compare the effectiveness of IVUS and OCT in reducing major adverse cardiovascular events (MACE).
Main Methods:
- A systematic review and meta-analysis of randomized controlled trials (RCTs) comparing imaging-guided versus angiography-guided PCI.
- Search of major databases through December 2025 for relevant RCTs.
- Pooled analysis of outcomes using random-effects models, risk ratios (RRs), and 95% confidence intervals (CIs).
- Inclusion of Trial Sequential Analysis (TSA) and exploratory Network Meta-Analysis (NMA).
Main Results:
- Analysis of 5 RCTs involving 3,023 patients revealed a significant reduction in MACE with imaging-guided PCI compared to angiography-guided PCI (RR 0.58, 95% CI 0.46-0.74).
- Subgroup analyses showed significant MACE reduction with both IVUS-guided PCI (RR 0.53, 95% CI 0.39-0.73) and OCT-guided PCI (RR 0.49, 95% CI 0.28-0.87).
- TSA supported the beneficial effect of imaging guidance, and NMA indicated comparable outcomes between IVUS and OCT, both superior to angiography.
Conclusions:
- Intravascular imaging-guided PCI demonstrably reduces MACE in patients with multivessel coronary artery disease.
- The findings underscore the clinical utility of intravascular imaging (IVUS and OCT) in this patient cohort.
- Both IVUS and OCT provide similar benefits, supporting their integration into routine practice for complex PCI procedures.
Background:
Percutaneous coronary intervention (PCI) in patients with multivessel coronary artery disease is associated with increased anatomical complexity and adverse cardiovascular outcomes. Conventional angiography provides limited assessment of vessel structure and plaque characteristics, whereas intravascular imaging with intravascular ultrasound (IVUS) or optical coherence tomography (OCT) may improve procedural guidance. However, the clinical impact of imaging-guided PCI in this population remains uncertain.
Methods:
We conducted a systematic review and meta-analysis of randomized controlled trials comparing intravascular imaging-guided versus angiography-guided PCI in patients with multivessel coronary artery disease regarding major adverse cardiovascular events (MACE). Major databases were searched through December 2025. Outcomes were pooled as risk ratios (RRs) with 95% confidence intervals (CIs) using random-effects models. Trial sequential analysis (TSA) and an exploratory network meta-analysis (NMA) were performed.
Results:
Five randomized trials, including 3,023 patients, were analyzed. Imaging-guided PCI was associated with a significant reduction in MACE compared with angiography-guided PCI (RR 0.58, 95% CI 0.46 to 0.74; p < 0.0001; I2 = 9.8%). In subgroup analyses by imaging modality, IVUS-guided PCI was associated with a reduction in MACE (RR 0.53, 95% CI 0.39 to 0.73; p < 0.0001; I2 = 0%), as was OCT-guided PCI (RR 0.49, 95% CI 0.28 to 0.87; p = 0.014; I2 = 24.3%). TSA provided supportive evidence for a beneficial effect of imaging-guided PCI. NMA suggested that both IVUS and OCT were associated with improved outcomes compared with angiography, with no significant difference between the two imaging modalities.
Conclusion:
Intravascular imaging-guided PCI is associated with a reduction in MACE in patients with multivessel coronary artery disease. These findings support the clinical value of intravascular imaging in this population, with similar effects observed across imaging modalities.
