New-Onset Atrial Fibrillation After Aortic Valve Replacement
New-Onset Atrial Fibrillation After Aortic Valve Replacement
Despite its limitations, this was the first study to evaluate the incidence of new-onset atrial fibrillation among elderly patients with degenerative AS who underwent SAVR compared with different TAVR approaches. New-onset AF was found in more than 40% of patients, with the highest incidence in the surgical group, followed by TA-, TAo-, and TF-TAVR approaches, respectively. Pericardiotomy appeared to be the most important technical factor associated with new-onset AF. Randomized controlled trials studying the impact of access site on the incidence of AF in TAVR are warranted.
