Objectives We aimed to explore the impact of 7‐Fr sheaths on the incidence of early radial artery occlusion (RAO) after transradial coronary intervention (TRI) in Chinese patients. Background RAO precludes future use of the vessel for vascular access. Transradial catheterization is usually performed via 5‐Fr or 6‐Fr catheters; 7‐Fr sheath insertion enables complex coronary interventions but may increase the RAO risk. Methods We prospectively enrolled 130 consecutive patients undergoing complex TRI using 7‐Fr sheaths. Radial artery ultrasound assessment was performed before and after TRI. Early RAO was defined as the absence of flow on ultrasound within 6–24 hr after TRI. Multivariate logistic regression was used to determine the factors related to early RAO after TRI. Results 7‐Fr sheaths were mainly used for chronic total occlusion (44.6%), bifurcation (30.0%), and tortuous calcification (25.4%) lesions. All patients were successfully sheathed. Percutaneous coronary intervention (PCI) procedural success was 96.2%; 119 patients (91.5%) had preserved radial artery patency after TRI. All 11 RAO cases (8.5%) were asymptomatic. The radial artery diameter was significantly larger postoperatively (3.1 ± 0.4 mm) than preoperatively (2.6 ± 0.5 mm) ( p < .001). No parameters significantly differed between patients with and without RAO. TRI history was the only independent risk factor of early RAO (odds ratio: 6.047, 95% confidence interval: 1.100–33.253, p = .039). Conclusions 7‐Fr sheath use after transradial access for complex PCI is feasible and safe. Evaluating the radial artery within 24 hr after TRI allows timely RAO recognition, important for taking measures to maintain radial artery patency and preserve access for future TRIs.
