ObjectivesThe aim of this study was to determine baseline characteristics and clinical outcomes of patients with pre-existing atrial fibrillation (AF) and of patients who presented with new-onset AF after transcatheter aortic valve implantation (TAVI).BackgroundLittle is known regarding the impact of AF after TAVI.MethodsThe FRANCE-2 registry included all patients undergoing TAVI (N = 3,933) in France in 2010 and 2011. New-onset AF was defined as the occurrence of AF post-procedure in a patient with no documented history of AF.ResultsAF was documented before TAVI in 25.8% of patients. New-onset AF was observed in 174 patients after TAVI among patients without a history of pre-existing AF (6.0%). At 1 year, the rates of all-cause death (26.5 vs. 16.6%, respectively; p < 0.001) and cardiovascular death (11.5 vs. 7.8%, respectively; p < 0.001) were significantly higher in patients with pre-existing AF compared with those without AF. Rehospitalization for worsening heart failure and New York Heart Association functional class was also higher in patients with pre-existing AF versus those without, resulting in a higher rate of combined efficacy endpoint in this group (p < 0.001). A history of stroke, surgical (nontransfemoral) approach, cardiological, and hemorrhagic procedure-related events were all independently related to the occurrence of new-onset post-procedural AF. New-onset AF in patients without pre-existing AF was associated with a higher rate of combined safety endpoint at 30 days (p < 0.001) and a higher rate of both all-cause death and combined efficacy endpoint at 1 year (p = 0.003 and p = 0.02, respectively).ConclusionsPre-existing and new-onset AF are both associated with higher mortality and morbidity after TAVI.
