Early vs Late Staged Percutaneous Coronary Intervention (PCI) After Subintimal Tracking and Re-Entry for Chronic Total Occlusions: A Randomized Trial
Authors' conclusion
Although vessel patency was higher at the start of early staged procedures, there were no statistically significant differences for partial technical success of the staged procedure with early or late treatment.
Study context
- Population
- Patients undergoing chronic total occlusion (CTO) PCI with subintimal tracking and re-entry (STAR) and deferred stenting
- Participants
