Safety and Efficacy of EBU 3.0 Guider for Right Coronary Artery (RCA) Interventions via Right Radial Approach

Abstract

Background:  Arterial access via the trans- radial route is preferred approach for percutaneous coronary intervention (PCI) in contemporary practice⁰¹. Judkins Right (JR) catheters are normally used for right coronary artery (RCA) PCI in our set-up. However, stronger guide support and improved coaxial alignment are often required which enhances procedural effectiveness.

Place and duration of study: Jan 2025 to June 2025, Cardiology Department, Sandeman Provincial Hospital Quetta.

Methods: The above prospective observational study was done on  200 patients undergoing RCA PCI via the right radial access. Procedures were performed using either Extra Backup (EBU) 3.0 or JR guide catheters. Procedural success, fluoroscopy time, contrast volume, catheter exchange rate, and in-hospital outcomes were evaluated.
Results: Angiographic procedural success was comparable in both groups (96%). The EBU group demonstrated significantly lower fluoroscopy time (9.2 ± 2.3 vs 12.1 ± 3.4 minutes, p<0.001) and contrast volume (110 ± 25 vs 140 ± 35 mL, p<0.001). Catheter exchange was required less frequently in the EBU group (4% vs 15%, p=0.01).
Conclusion: EBU guiding catheters are a safe alternative for PCI of right coronary artery via the right radial arterial access.

Conclusion: EBU guiding catheters are a safe and effective alternative to JR catheters for RCA PCI via right radial access.
