Abstract

Recently, coronary angiography (CAG) and percutaneous coronary intervention (PCI) via the distal radial access (DRA), are gaining attention owing to fewer complications. Despite the advantages of the DRA, there is difficulty to initiate this new vascular approach. The data from 1000 patients who underwent CAG and PCI via the DRA by a single experienced radial operator were retrospectively analyzed. The primary outcome was the success rate of the DRA per 100 cases. Moreover, the predictors of the failed DRA were analyzed. Overall, 952 (95.2%) of the total 1,000 patients underwent a successful DRA. After experiencing 200 cases, the DRA success rate was well maintained at > 94%, and there was no difference in success rate per 100 cases (P = 0.216). The predictors of failure were female sex [odds ratio (OR) 1.84, 95% confidence interval (CI) 1.01-3.39, P = 0.049] and systolic blood pressure (SBP) of < 120 mmHg (OR 1.87, 95% CI 1.04-3.36, P = 0.036). For achieving a stable DRA with the success rate of > 94%, 200 procedures would be needed. Moreover, this new approach could fail in women and patients with low SBP.Trial registration: https://cris.nih.go.kr/cris/index/index.do (Unique identifier: KCT0005349).
