Resum:
Introduction and objectives: Distal radial access (DRA) for coronary procedures is currently recognized as an alternative to conventional transradial access, with documented advantages primarily related to access-related complications. However, widespread adoption of DRA as the default approach remains limited. Therefore, this prospective cohort study aimed to present our initial experience with DRA for coronary procedures in any clinical settings. Methods: From August 2020 to November 2023, we included 1000 DRA procedures (943 patients) conducted at a single center. The study enrolled a diverse patient population. We recommended pre- and postprocedural ultrasound evaluations of the radial artery course, with ultrasound-guided DRA puncture. The primary endpoint was DRA success, while secondary endpoints included coronary procedure success, DRA performance metrics, and the incidence of access-related complications. Results: The DRA success rate was 97.4% (n = 974), with coronary procedure success at 96.9% (n = 969). The median DRA time was 40 [interquartile range, 30-60] seconds. Diagnostic procedures accounted for 64% (n = 644) of cases, while 36% (n = 356) involved percutaneous coronary intervention (PCI), including primary PCI in 13% (n = 128). Pre-procedure ultrasound evaluation and ultrasound-guided DRA were performed in 83% (n = 830) and 85% (n = 848) of cases, respectively. Access-related complications occurred in 2.9% (n = 29). Conclusions: This study shows the safety and feasibility of DRA for coronary procedures, particularly when performed under ultrasound guidance in a diverse patient population. High rates of successful access and coronary procedure outcomes were observed, together with a low incidence of access-related complications. The study was registered on ClinicalTrials.gov (NTC06165406).
