Intravascular imaging-guided vs. angiography-guided percutaneous coronary intervention: A systematic review and meta-analysis of randomized controlled trials in high-risk patients and complex coronary anatomies.

Background: Despite a large body of evidence supporting the use of intravascular imaging (IVI) to guide percutaneous coronary intervention (PCI), concerns exist about its universal recommendation. The selective use of IVI to guide PCI of complex lesions and patients is perceived as a rational approach.

Methods: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs).
