Inclusion criteria

Inclusion criteria: This study included patients with AF who underwent AF ablation and preprocedural contrast-enhanced CT.

Exclusion criteria

Exclusion criteria: The patients who did not undergo contrast-enhanced CT because of contrast agent allergy and/or chronic kidney disease, and missing data regarding the venous phase of contrast-enhanced CT before catheter ablation were excluded.

Design outcomes

Primary

Measure	Time frame
The ability to detect the right pericardiophrenic bundles using the venous as well as arterial phases of contrast-enhanced CT. To ascertain whether three-dimensional reconstruction of pericardiophrenic bundles from CT data could locate the running course of the PN detected by electrical phrenic pace map. What factors influence the detection of right pericardiophrenic bundles on contrast-enhanced CT?	—
