Imaging-guided percutaneous coronary intervention (PCI) may reduce the need for repeat procedures compared to physiology-guided PCI. This finding holds true regardless of acute coronary syndromes (ACS) presentation.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Imaging
Background:
- Percutaneous coronary intervention (PCI) is a key revascularization method for coronary artery disease.
- The optimal guidance strategy for PCI, between imaging and physiology, remains debated.
- Intermediate coronary lesions (ICLs) present a particular challenge in PCI decision-making.
Purpose of the Study:
- To systematically compare clinical outcomes of imaging-guided versus physiology-guided PCI.
- To evaluate the effectiveness of these guidance strategies in managing intermediate coronary lesions (ICLs).
- To assess the influence of acute coronary syndromes (ACS) presentation on PCI outcomes.
Main Methods:
- A meta-analysis of seven eligible studies involving 5701 patients, adhering to PRISMA guidelines.
- Literature search conducted across major databases up to December 2023.
- Outcome measures included major adverse cardiovascular events (MACE), target vessel revascularization (TVR), target vessel failure (TVF), and target lesion revascularization (TLR).
Main Results:
- Imaging-guided PCI was associated with significantly lower rates of target vessel revascularization (TVR) (OR 0.70, p=0.02) compared to physiology-guided PCI.
- No significant differences were observed in major adverse cardiovascular events (MACE), target vessel failure (TVF), or target lesion revascularization (TLR) between the two strategies.
- Subgroup analysis for intermediate coronary lesions (ICLs) and meta-regression for acute coronary syndromes (ACS) presentation showed no significant differences.
Conclusions:
- Imaging-guided PCI may offer an advantage by reducing the need for subsequent target vessel revascularization.
- The choice of guidance strategy did not significantly impact major adverse cardiovascular events or outcomes in patients with acute coronary syndromes.
- These findings support informed clinical decisions regarding PCI guidance strategies.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
