Pulmonary vein narrowing after pulsed field versus thermal ablation

  Figure 1. Example cardiac CT measurements showing the short and long diameter measurements (A) and images reconstructed in 3D renderings to show pre-procedural and 90-day pulmonary vein dimensions for a patient treated with PFA (B, C) and thermal (RF) ablation (D, E). P, posterior; PFA, pulsed field ablation; RF, radiofrequency; S, superior.

  Figure 4. Pulmonary vein diameter changes categorized per patient. PFA, pulsed field ablation; PV, pulmonary vein; RFA, radiofrequency.
