BACKGROUND: Atrial arrhythmogenic substrate is a key determinant of atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI), and reduced conduction-velocities have been linked to adverse outcome. However, a non-invasive method to assess such electrophysiological substrate is not available to date. OBJECTIVE: This study aimed to non-invasively assess regional conduction-velocities and their association with arrhythmia-free survival following PVI...
