Key inclusion criteria

We analyzed consecutive patients with AF who were referred to the Toyama Prefectural Central Hospital in Japan between April 2025 and September 2025 and underwent catheter ablation using PFA systems.

Key exclusion criteria

Patients with mild tricuspid regurgitation(TR) in whom a clear TR Doppler envelope could not be obtained were excluded. Patients lacking either inspiratory/expiratory phases of inferior vena cava diameters were also excluded.
