Background:
The mechanisms and predictors of failure of the transradial approach in centers dedicated to this technique are not well characterized and were the main objective of this analysis.
Methods:
6,808 consecutive patients undergoing transradial coronary procedures by operators with utilization rate greater than 90% were included. Simple and multiple logistic regression models were used to identify the predictors of failed transradial approach.
Results
Transradial failure rate was 1.7%. Vascular complications were observed in 5% of the sample, with a prevalence of asymptomatic arterial occlusion and subcutaneous hematomas. Predictors of failure were female gender (OR = 1.87; 95% CI: 1.29-2.71; p = 0.01), age > 70 years (OR = 1.78; 95% CI: 1.06-2.98; p = 0.03) and presence of chronic peripheral arterial disease (OR = 5.71; 95% CI: 2.40-13.54; p < 0.01).
Conclusions
In a high-volume radial center, the failure rate was < 2% and variables associated with failure of the technique were female gender, advanced age and peripheral arterial disease.
