Coronary disease & ACSCohort study
Distal Radial Access for Coronary Procedures in a Large Prospective Multicenter Registry
- Prospective multicentre registry
- 14 hospitals
Authors' conclusion
In this large-scale prospective multicenter registry, DRA demonstrated high success rates of CAG and PCI, with a high rate of puncture success but low rates of distal radial artery occlusion, radial artery occlusion, bleeding events, and procedure-related complications. Weak pulse and DRA experience <100 cases were predictors of puncture failure.
Study context
- Population
- Patients undergoing coronary angiography or percutaneous coronary intervention (PCI) via distal radial access, 14 Korean hospitals, September 2019 – September 20215,712 screened
- Participants
- 4,977 patients
- Outcome
- Success rates of coronary angiography (CAG) and PCI
