Does generator-impedance mapping improve the delineation of atrial septal occluders compared to bipolar voltage mapping in patients undergoing catheter ablation for atrial tachyarrhythmias?
Generator-impedance mapping provides a stable and clinically actionable representation of atrial septal occluder boundaries on electroanatomic maps, facilitating safe ablation-line planning adjacent to the device.
Yoshiyama et al. (Fri,) studied this question.
