Authors' conclusion

In the present randomized trial comparing IVUS-guided vs angiography-guided PCI for complex coronary bifurcation lesions treated with the 2-stent DK crush technique, the benefits of IVUS-guided PCI at 1 year was achieved largely through achievement of IVUS-defined optimization targets rather than IVUS use alone.

Study context

Population
Patients with clinical indications for percutaneous coronary intervention (PCI) and a complex bifurcation lesion by DEFINITION criteria (particularly side branch lesion length ≥10 mm)
Participants
555 patients
Comparison
IVUS-guided PCI vs angiography-guided PCI
  • IVUS-guided PCIn = 277
  • Angiography-guided PCIn = 278reference
Primary endpoint
Target vessel failure:
  • Cardiac death
  • Target vessel MI
  • Clinically driven target vessel revascularization
Follow-up
1 year after randomization
