Safety and efficiency of percutaneous coronary intervention using a standardised optical coherence tomography workflow
Authors' conclusion
The incorporation of a standardised pre- and post-PCI OCT imaging workflow improves procedural efficiency and safety metrics, at a cost of a modestly longer procedure time.
Study context
- Population
- Percutaneous coronary intervention (PCI) procedures by 45 physicians at 17 US centres over 2 years207 matched procedures
- Participants
- 264 vs 428
- Exposure
- Optical coherence tomography (OCT)-guided PCI with standardised LL workflow vs angiography-only PCI
- LL workflown = 264
- Angion = 428reference
- Outcome
- Procedural efficiency and safety metrics

Main finding
As reported in the abstract
- Median procedural time increased with LL workflow (minutes)
- 9
- Vessel preparation time (min): LL workflow 2 vs angio 3
- p<0.001
- Unplanned additional treatment: LL workflow 4% vs angio 10%
- p=0.01
- Radiation exposure (mGy): LL workflow 1,133 vs angio 1,269
- p=0.02
- No difference in contrast utilisation
- p=0.28
Observational data: associations, not effects.
Further findings
Device utilisation and treatment strategy
- Fewer cineangiography views, predilatation balloons and stents, more direct stenting and greater stent post-dilatation with LL workflow
