Temporal Trends and Predictors of Access Site Crossover During Percutaneous Coronary Intervention (PCI) in Contemporary Practice: A Report From the NCDR CathPCI Registry
- Registry analysis
Authors' conclusion
In contemporary clinical practice, access site crossover rates are consistent with those reported in randomized trials. Although crossover occurs more frequently among lower-volume operators, rates decline with increasing operator experience, supporting the presence of a radial access learning curve and improvement in procedural performance over time.
Study context
- Population
- Index PCI procedures recorded in the National Cardiovascular Data Registry CathPCI Registry from 2018 to 2024
- Participants
- 3,861,790 index PCIs
Main finding
As reported in the abstract
Access site crossover
Index PCIs involving access site crossover
192 902 (5.0%)
Observational data: associations, not effects.
Further findings
Radial-to-femoral crossover share of crossover events
- Radial-to-femoral crossover accounted for crossover events
- 81.2%
Factors independently associated with crossover
- Older age, female sex, higher body mass index, and peripheral vascular disease
Crossover by operator volume
- Operators with the lowest total PCI volume and the lowest radial PCI volume experienced the highest crossover rates
- Operators with low radial PCI volume demonstrated a substantial decline in radial-to-femoral crossover over the study period
