Intra-cardiac ultrasound guided approach for catheter ablation of typical right free wall accessory pathways

摘要

Schematic representation of the “loop” manoeuvre - the steerable long sheath (light grey curve pointing downwards) and the ablation catheter (dark grey curve pointing upwards) position in a case of anterior right free wall accessory pathway ablation. Also, division of the free wall aspect of the tricuspid annulus is shown with green dots representing each individual accessory pathway location. CS coronary sinus.
