Dual Access Rapid Trap for Augmentation of Guide Catheter Support in the Left Coronary System.

Coaxial trapping of guide extension catheters within a coronary artery allows for maximal support in delivering equipment; however, use of this technique within the left main coronary artery has been avoided due to concerns surrounding hemodynamic instability and vessel injury. We describe our initial experience with impromptu coaxial trapping of guide extension catheters within the left main coronary artery using the dual access rapid trap (DART) technique. Coaxial trapping of guide extension catheters within the left main coronary artery using DART enabled successful equipment delivery across balloon-uncrossable lesions. This case demonstrates that DART is a safe and effective method for equipment delivery across balloon-uncrossable lesions and may aid operators in safely solving complex cases.
