Temporal Trends and Predictors of Access Site Crossover During Percutaneous Coronary Intervention (PCI) in Contemporary Practice: A Report From the NCDR CathPCI Registry
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
- Outcome
- Access site crossover
Main finding
As reported in the abstract
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
