Implication

Contact force-guided CPVI was associated with higher 12-month success; hypothesis-generating for randomized trials in paroxysmal AF.

Structured PICO

Does contact force-guided CPVI reduce AF recurrence and residual conduction gaps compared to conventional CPVI in patients with paroxysmal atrial fibrillation?

Population

100 consecutive patients with paroxysmal atrial fibrillation (PAF) undergoing circumferential pulmonary vein isolation (CPVI). Conventional group mean age 61 ± 10 years, CF group mean age 65 ± 11 years.

Intervention

Contact force (CF)-guided circumferential pulmonary vein isolation (CPVI) using a ThermoCool SmartTouch catheter

Comparator

Conventional (non-CF-guided) CPVI using a ThermoCool EZ Steer catheter

Outcome

Atrial fibrillation (AF) recurrence-free rates at 12-month follow-up

Contact force-guided CPVI significantly reduces procedure time, fluoroscopy time, residual conduction gaps, and AF recurrence at 12 months compared to conventional CPVI in patients with paroxysmal AF.
