Why the study?
How has the 1-year risk of recurrent atrial fibrillation following first-time ablation changed between 2006 and 2014?
How has the 1-year risk of recurrent atrial fibrillation following first-time ablation changed between 2006 and 2014?
The 1-year risk of recurrent atrial fibrillation after first-time ablation decreased by nearly 50% from 2006 to 2014 in Denmark.
Answers are grounded in this paper and cite their sources.
Declining recurrent AF risk after ablation may inform expectations; leaves open whether benefits persist in contemporary practice without RCTs.
One year risk of recurrent AF following first-time ablation has almost halved from 2006 to 2014. Hypertension, female sex, cardioversion 1 year prior to ablation, and AF duration for more than 2 years all increased the associated risk of recurrent AF.
