Key result
Two hundred cases of distal radial access for coronary intervention were required to overcome the learning curve and maintain a consistently high success rate of >94%.
Why the study?
Despite the advantages and fewer complications of distal radial access for CAG and PCI, initiating this vascular approach presents difficulty, leaving its learning curve uncertain.
Does operator experience improve the success rate of distal radial access for coronary intervention, and what are the predictors of failure?
Population
1000 patients undergoing CAG and PCI via the DRA by a single experienced operator
Comparison
DRA success rate per 100 cases over time
Design
Retrospective observational cohort study

p-value: p=<0.001
A learning curve of approximately 200 cases is required to achieve a consistently high success rate (>94%) for distal radial access in coronary interventions, with female sex and low systolic blood pressure predicting failure.
Roh et al. (2021) conducted an observational in Suspected ischemic heart disease (n=1,000). Distal radial access (DRA) was evaluated on Success rate of the DRA per 100 cases (p=<0.001). Two hundred cases of distal radial access for coronary intervention were required to overcome the learning curve and maintain a consistently high success rate of >94%.
