Key result
High-density PentaRay mapping is linked to shorter ACHD ablations and less radiation versus standard mapping.
Why the study?
Ablation of atrial tachyarrhythmia in ACHD is challenging due to complex anatomy and high scar burden, prompting evaluation of whether adding PentaRay high-density mapping to 3D EAM enables rapid high-resolution mapping and shorter procedure times.
Does the addition of the PentaRay high-density mapping catheter to standard EAM reduce procedure time and radiation exposure in adults with congenital heart disease undergoing atrial tachyarrhythmia ablation?

Does the addition of the PentaRay high-density mapping catheter to standard EAM reduce procedure time and radiation exposure in adults with congenital heart disease undergoing atrial tachyarrhythmia ablation?
p-value: p=.015
The addition of the PentaRay high-density mapping catheter to standard EAM for atrial tachyarrhythmia ablation in ACHD patients significantly reduces procedure time and radiation exposure.
Dodeja et al. (2022) conducted a cohort in Atrial tachyarrhythmia in adults with congenital heart disease (n=23). High-density mapping with PentaRay catheter plus 3D electroanatomic mapping (EAM+P) vs. Standard 3-dimensional electroanatomic mapping (EAM) was evaluated on Procedure duration (p=.015). High-density mapping with the PentaRay catheter for atrial tachyarrhythmia ablation in ACHD reduced procedure duration (P=0.015) and radiation exposure (P=0.001) compared to standard mapping.
