Patients who have symptomatic, drug-refractory recurrence of AF will be randomized to either a redo AF ablation vs conduction system pacing with AV node ablation. Patients will need to have undergone at least 1 prior AF ablation to be considered eligible for the study. The current trial is a vanguard study of 16 patients and will determine the feasibility of enrolment, compare changes in quality of life, and inform the design of the definitive REDO AF trial.",[69,70,71],"Atrial Fibrillation (AF)","AV Node Ablation","Left Bundle Branch Pacing",[73,74,75,76,77,78],"Atrial fibrillation","pace and ablate","AV node ablation","Left bundle branch pacing","LBBP","Redo","NOT_YET_RECRUITING","2025-11-20",{"date":82,"type":83},"2025-11-24","ACTUAL",{"date":85,"type":63},"2025-11",{"date":87,"type":63},"2027-09",{"name":51,"class":6},1]
