Background: Transradial coronary angiography (TR) is becoming more commonly utilized because it was associated with fewer vascular complications of access sites compared to transfemoral coronary angiography. TR also improved patient comfort. However TR attempts were occasionally unsuccessful and operators would perform transfemoral approach. This study reported an analysis of patient characteristics as predictors for transradial approach failure during coronary angiography procedures.
Methods: A collection of 10,023 coronary angiograms from University of South Dakota Sanford School of Medicine, at Sanford Heart Hospital from 2011 to 2015 was retrospectively analyzed. 7,884 cases started out as transradial, and 1,114 (14.1%) of these cases required crossover from transradial to transfemoral (TRF). These results were examined to evaluate potential patient characteristics that correlate with TRF crossover group compared to TR.
Results: Figure A showed Odd Ratio (OR) between TR and TRF crossover group. Cases with statistically significant OR of a TRF crossover involved patients with STEMI (p<0.0001), history of prior coronary artery bypass graft (CABG) (p<0.0001), and patients with ages of 70+ (p<0.0001). Patients with ages < 70 had a statistically significant OR of completion of procedure through TR (p<0.0001).
Conclusions: STEMI, history of CABG, and age of greater than 70 years old were predictors of TR failure. Patients with ages < 70 had successful completion of TR access.
