CEREBRAL EMBOLISMS
The aim of the Embo‐Abl study will be to compare the incidence of cerebral embolisms on 3 T diffusion‐weighted image magnetic resonance imaging (MRI) after CA of AF between CB and RF ablation in patients with AF in a prospective, multicenter, open‐label, controlled, randomized fashion. The primary endpoint of the Embo‐Abl study will be the occurrence of MRI‐detected SCE 1–3 days after CA. The patients will be registered and randomly assigned to either the CB or RF ablation group in a 1:1 ratio. The study cohort will include 230 patients with AF from a multicenter in Japan.
