Authors' conclusion

In patients with complex coronary artery lesions undergoing PCI, intravascular imaging guidance reduced the risk of a composite of cardiac death, target vessel-related myocardial infarction, or clinically driven target vessel revascularization at median follow-up of 5.3 years, compared to angiography guidance.
