Intra-cardiac echocardiography (ICE) image taken during mapping and ablation of the an-terior right free wall accessory pathway (AP). The 10 Fr (French scale) ICE probe was in-serted into the right atrium via the femoral vein. The ablation catheter was inserted into the right ventricle via a steerable long sheath and the described “loop” manoeuvre was used. White lines mark the presumed location of the steerable long sheath, yellow lines mark the course of the ablation catheter loop. The tip of the ablation catheter is marked with a solid white arrow, the tricuspid valve is marked with solid white arrowheads. RA right atrium, RV right ventricle, Ao aorta.
