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%\u00a0vs 6.8%, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001), but AMR prevalence was similar between genders (1.9%\u00a0vs .9%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.443). Variables related to greater ATR severity were: female sex (OR: 2.61, 95%CI: 1.60\u20134.24), left atrial (LA) volume (OR: 3.58, 95%CI: 1.50\u20138.55), systolic pulmonary artery pressure (OR: 1.10, 95%CI: 1.07\u20131.13), and moderate AMR (OR: 2.21, 95%CI: 1.22\u20134.00). Variables related to greater AMR severity were female sex (OR: 1.96, 95%CI: 1.24\u20133.09), LA volume (OR: 11.68, 95%CI: 5.29\u201325.80), and body mass index (OR: .94, 95%CI: .90\u2013.98).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In the context of AFib, ATR was more prevalent than AMR and prevailed in women. LA enlargement was associated with higher degrees of both AMR and ATR. Pulmonary hypertension was also independently associated with ATR, as well as greater AMR severity, suggesting possible adaptive changes in leaflets that might modify the atrial regurgitation
