Abstrakt:	Background: Many techniques exist for venous access (VA) during cardiac implantable electronic device (CIED) implantation. Objective: We sought to evaluate the learning curve with ultrasound (US) guided axillary vein access (USAA). Methods: Single‐center prospective randomized controlled trial of patients undergoing CIED implantation. Patients were randomized in a 2:1 fashion to USAA versus conventional VA techniques. The primary outcomes were the success rates, VA times and 30‐day complication rates. Results: The study included 100 patients (age 68 ± 14 years, BMI 27 ± 4 kg/m2). USAA was successful in 66/70 implants (94%). Initial attempts at conventional VA included 47% axillary (n = 14), 30% (n = 9) cephalic, and 23% (n = 7) subclavian. The median access time was longer for USAA than conventional access (8.3 IQR 4.2–15.3 min vs. 5.2 IQR 3.4–8.6 min, p =.009). Among the five inexperienced USAA implanters, there was a significant improvement in median access time from first to last tertile of USAA implants (17.0 IQR 7.0–21.0 min to 8.6 IQR 4.5–10.8 min, p =.038). The experienced USAA implanter had similar access times with USAA compared with conventional access (4.0 IQR 3.3–4.7 min vs. 5.2 IQR 3.4–8.6 min, p =.15). Venograms were less common with USAA than conventional access (2% vs. 33%, p <.0001). The 30‐day complication rate was similar with USAA (n = 4/70, 6%) versus conventional (n = 3/30, 10%, p =.44). Conclusion: Although the success rate with USAA was high, there was a significant learning curve. Once experienced with the USAA technique, there is the potential for reduced complications without adding to the procedure duration. [ABSTRACT FROM AUTHOR]
