Background This study aimed to examine the prevalence of atrial tricuspid regurgitation (ATR) and atrial mitral regurgitation (AMR) in the setting of atrial fibrillation (AFib) and identify variables related to the severity of both types of regurgitation. Methods Cross‐sectional study evaluating data from transthoracic echocardiograms performed during 2019. We included patients with AFib during the examination, and without primary valve disease or other significant heart disease. Results Four‐hundred and thirty‐two patients fulfilled the inclusion criteria (mean age 77.5±9.2 years, 49.1% women). We observed significant ATR in 14.8%, and significant AMR in 1.4% of patients. ATR and AMR severities were equal in 49.3% of patients, and 41% displayed greater ATR severity. ATR prevalence was significantly greater among women (23.1% vs 6.8%, p
