Jet Ventilation Catheter stability and catheter contact during LA ablation are crucial for effective lesion creation. Both catheter stability and catheter–tissue CF can be further increased by reduced respiratory thoracic excursions. Data from one institution suggest improved clinical outcome as a result of enhanced lesion quality and reduction of PV reconnection when applying high-frequency jet ventilation in general anesthesia during PVI.634,864,865 Further data from other centers are needed, however, before final conclusions can be drawn. A survey of the writing group members reveals that in the United States and Canada, 14% routinely employ high-frequency jet ventilation. Outside the United States and Canada, 4% routinely employ high-frequency jet ventilation during AF ablation procedures.
