Key result
QDOT Micro catheter's 90 W short-duration ablation potentially improves persistent AF safety and efficacy.
Why the study?
Ablation targets for persistent atrial fibrillation remain poorly understood because pulmonary vein isolation alone is ineffective due to left atrial structural alterations.
The QDOT Micro catheter enables temperature-controlled, very high-power short-duration ablation, potentially increasing the safety and efficacy of treating persistent atrial fibrillation.

May inform persistent AF ablation strategies; leaves open randomized confirmation of safety and efficacy.
Volpato et al. (2023) conducted a review in persistent atrial fibrillation. QDOT Micro catheter was evaluated. The QDOT Micro catheter enables temperature-controlled, very high-power short-duration ablation up to 90 W, potentially increasing the safety and efficacy of persistent atrial fibrillation treatment.
