Fluoroless coronary sinus cannulation using a BeeAT catheter and the CARTO mapping system.

ABSTRACT: Fluoroscopy-free ablation techniques have gained popularity in recent years. However, coronary sinus (CS) cannulation via the femoral approach remains technically challenging, particularly when using specialized catheters like the BeeAT™. To demonstrate a reproducible technique for fluoroscopy-free CS cannulation using the BeeAT catheter guided by CARTO® electroanatomical mapping and intracardiac echocardiography (ICE). Forty three patients undergoing atrial fibrillation ablation were enrolled. After 3D mapping of the right atrium and CS ostium identification via ICE, a femoral-type BeeAT catheter was inserted. Direct advancement or RA loop techniques were applied based on anatomy. CARTO settings were adjusted to allow impedance-based catheter visualization. Successful CS cannulation witho
