Abstract

Pre-existing atrial fibrillation (AF) is common among patients who underwent transcatheter aortic valve implantation (TAVI) and has been associated with adverse outcomes. The specific impact of AF at baseline in women who underwent TAVI, however, remains unknown. The Women's International Transcatheter Aortic Valve Implantation is a prospective, multinational registry evaluating the safety and performance of contemporary TAVI in women in 19 centers between January 2013 and December 2015. Patients with available electrocardiogram at baseline were compared according to the presence of AF. All events were adjudicated according to the Valve Academic Research Consortium 2 criteria. Associations between AF and outcomes were tested using multivariate Cox regression model. Of the 993 women with available baseline electrocardiogram included in the study, 200 (20.1%) presented with AF. Patients with AF at baseline had higher Euroscore I score values and more frequently had chronic kidney disease or prior stroke. Patients without AF more frequently had coronary artery disease. There was no difference regarding in-hospital events between the two groups aside from longer length of stay for patients with AF (13.3 +/- 11 vs 11.5 +/- 7.1 days, p = 0.01). In multivariate analysis, AF at baseline was associated with an increase of all-cause and cardiovascular death at 12 months (adjHR 1.67 95 % CI 1.11 to 2.50, p = 0.013 and adjHR 1.85 95 %CI 1.19 to 2.86, p = 0.006 respectively). In conclusion, in this prospective registry of women who underwent contemporary TAVI, the presence of AF at baseline was associated with significantly increased 12-month mortality.
