Between March 2020 and February 2022, 31 patients were recruited. Of these, 15 patients were randomized to left‐sided ablation and 16 patients were randomized to right‐sided ablation. The clinical characteristics at baseline did not differ significantly between the groups (Tables Baseline characteristics of patients.Abbreviations: BMI, body mass index; COPD, chronic obstructive pulmonary disease; CRT cardiac resynchronization therapy; TIA, transient ischemic attack.Previous medication usage.Abbreviation: NOAC, novel oral anticoagulant.There were five crossovers from left‐sided ablation to right‐sided ablation. Two out of five crossovers were as per the study protocol with a switch to right‐sided ablation after six unsuccessful RF applications. Three out of five crossovers were performed before any RF application on the left side. This was due to unstable catheter position in two cases, and inability to cross the aortic valve despite repeated attempts in one case. There was one crossover from the right side to left side that occurred as per the study protocol after six failed RF applications.
