Raises possibility of differential embolic signals with PVAC; leaves open clinical significance in human AF ablation.
Does PVAC ablation compared to irrigated radiofrequency ablation increase microbubble production in a swine model of pulmonary vein ablation?
In a swine model, pulmonary vein ablation with PVAC produced more microbubbles than irrigated radiofrequency, particularly when proximal and distal electrodes overlapped during bipolar energy delivery.
Haines et al. (2013) studied this question.
