Authors' conclusion

In CHIP patients, procedural planning and guidance on the basis of physiology (through either angiography- or microcatheter-derived FFR) are superior to conventional angiography for achieving optimal post-PCI FFR values.

Study context

Population
Patients with obstructive coronary lesions meeting complex high-risk indicated procedure (CHIP) criteria
Participants
