Implication

Should not change AF ablation practice; leaves open need for randomized trials to confirm durability.

Structured PICO

Population

51 consecutive symptomatic patients with paroxysmal (n = 20) or persistent (n = 31) atrial fibrillation undergoing initial RF ablation, mean age 68.4, 39.2% female, US-based. Excluded: longstanding persistent AF lasting >1 year.

Intervention

Radiofrequency (RF) ablation using 50 W power for very short durations (average 11.2 ± 3.7 s) with contact force (CF) sensing catheters (target CF 10–40 g).

Outcome

Single procedure freedom from atrial fibrillation at 1 and 2 years

Limitations

Single center study
Relatively small number of patients
Too small to evaluate for infrequent serious complications
