Low-Voltage Myocardium-Guided Ablation Trial of Persistent Atrial ...
WebAblation of low-voltage bridges was performed until no low-voltage connections were observed within the left atrium, including the PVs. Success was defined by 1) the absence of AF (primary endpoint); 2) freedom from sustained atrial tachycardia (secondary endpoint) documented by 30-day event monitors. WebOct 19, 2024 · We conducted a multicenter, randomized trial to determine whether PVI plus individualized substrate ablation of atrial low-voltage myocardium improves outcome in patients with persistent AF. We randomly assigned 324 patients in a 1:1 ratio to receive PVI alone (163 patients; PVI only) or PVI plus substrate modification (161 patients; PVI+SM). WebAug 25, 2024 · However, the optimal technique for persistent AF is not yet known although almost certainly it is not solely PVI.
