NCT04642976
Despite progress made in treating atrial fibrillation with catheter ablation, outcomes remain suboptimal with pulmonary vein isolation alone. Ablation of ganglionated plexi (GP) has been shown to be beneficial in patients with atrial fibrillation although optimal strategies of localization of these regions have yet to be determined. The investigators aim to develop a novel strategy of CT guided GP localization to guide ablation in patients with atrial fibrillation. The investigators also aim to clarify the network of innervation between GP to clarify the optimal ablation strategy. This is an observational, single-center study evaluating feasibility and efficacy of CT and high frequency stimulation (HFS) guided GP mapping and ablation in patients with AF undergoing catheter ablation with pulmonary vein isolation. Patients will undergo HFS and CT guided mapping of GPs followed by allocation into one of 8 different GP ablation approaches in a non-randomized fashion.
