  • Randomised controlled trial
  • prospective
  • multicentre
  • open-label

Coronary computed tomography angiography (CCTA) completed in 272/303 (89.8%) after median 200 days (IQR 181-270)

Authors' conclusion

Routine CCTA after LM PCI did not reduce the composite primary endpoint, but was associated with fewer spontaneous MIs and more imaging-triggered revascularizations.

Study context

Patients after PCI with second-generation drug-eluting stents for unprotected left main disease
Participants
