Intra-cardiac echocardiography (ICE) image taken during mapping and ablation of the pos-tero-lateral right free wall accessory pathway (AP). The “loop” manoeuvre was done as de-scribed in Fig. 2. White lines mark the presumed location of the steerable long sheath, yellow lines mark the presumed 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.
