Authors' conclusion
In a real-world cohort of patients undergoing CTO PCI, a DCB-based strategy, either alone or in combination with stents, was associated with favorable 1-year clinical outcomes. No significant differences were observed between DCB-only and blended treatment with a stent.
Study context
- Population
- Consecutive chronic total occlusion (CTO) percutaneous coronary intervention (PCI) patients treated with at least 1 drug-coated balloon (DCB) at 21 international centres
- Participants
- 938 patients
- Exposure
- DCB-only vs DCB + stent
- DCB onlyn = 476
- DCB + stentn = 462reference
- Outcome
- Target vessel failure:
- Cardiac death
- Target vessel MI
- Target vessel revascularization
- Follow-up
- 12 months
