Supports feasibility of single-catheter PVI but should not change practice; leaves open comparative efficacy versus standard techniques.
Does a single-catheter technique utilizing a decapolar catheter and duty-cycled RF generator safely and efficiently achieve pulmonary vein isolation in patients with atrial fibrillation?
A novel single-catheter technique with a duty-cycled RF generator achieved 99% pulmonary vein isolation with short procedure times and no complications in patients with atrial fibrillation.
Fredersdorf et al. (2009) studied Atrial fibrillation (n=21). Single-catheter technique using a decapolar catheter and duty-cycled RF generator was evaluated on Success rate at 6 months. A single-catheter technique for pulmonary vein isolation using a decapolar catheter and duty-cycled RF generator achieved a 99% acute isolation rate and an 86% success rate at 6 months.
