Noninvasive Visualization of the Atrioventricular Conduction System Using Cardiac Computed Tomography
Authors' conclusion
Results of this cohort study suggest that CECT could accurately localize the fatty tissue that insulates the AVCS from surrounding atrial and ventricular myocardium
Study context
- Population
- Patients with CECT <1 month before AF ablation and His electrogram localization on electroanatomic mapping, Jan 2022–Jan 2023
- Participants
- 20 patients
- Outcome
- Distance from His electrogram signal to fat segmentation encompassing the AV conduction system on CECT, after registration to electroanatomic mapping

Main finding
As reported in the abstract
Distance from His electrogram to closest AVCS fat voxel on CECT (after registration to electroanatomic mapping (EAM))
Mean (SD) distance from His electrogram to closest AVCS fat voxel
3.3 (1.6) mm
Observational data: associations, not effects.
Further findings
- Mean (SD) attenuation of AVCS fat segmentation
- 2.9 (21.5) Hounsfield units
