2025 AF Symposium Overview: Written for Atrial Fibrillation Patients
The 30th annual International AF Symposium was held in Boston January 16-18, 2025. (This is where the AF Symposium originally started back in 1995. I’ve been attending since 2003—that’s 23 years!
This intense 3-day seminar took place at the Omni Seaport hotel, a well-designed, ultra-modern conference venue. Coming from California, the January weather in Boston was considered relatively mild with temperatures in the 30s.

This Symposium featured presentations by 87 leaders in A-Fib research and clinical practice from all over the world. These medical scientists, clinicians, and researchers shared recent developments in the A-Fib field in a forum unmatched by any other conference. This year the Symposium attracted around 1,400 worldwide participants.
Major Theme: Case Transmissions Take Center Stage
The major theme or emphasis of the 2025 AF Symposium was live and prerecorded ablation cases transmitted from EP/labs and operating rooms from around the world. There were a record 24 cases presented in eight different sessions!
A majority of these cases were focused on Pulse Field Ablation (PFA). These case transmissions seemed to be among the most attended and popular sessions. A tip of the hat to all the people behind the scenes who made these seamless networking and streaming presentations work so well.
