Advances in Atrial Fibrillation Ablation Devices 39 2 cerebral embolism (20% vs. none, p=0.011) and a higher amount and duration of micro- embolic signals compared to irrigated RFCA in a randomized clinical trial from our centre (58). PNP is uncommon after PVAC ablation. It was first reported in 2010 (61) and occurred in only 1/272 (0.4%) consecutive patients (62). PVAC ablation is usually performed at the ostium of the PVs and a detectable narrowing of the PV diameter has been reported in 23% of patients and 7% of veins (14, 63, 64).
