2026 AF Symposium Challenging Cases in AF Management and Stroke Prevention

Published May 26, 2026

This is one of my personal favorite sessions, though it’s also one of the least attended (probably because people are leaving early to catch a plane home on the last day of the Symposium).

Dr. Horton described it as “huge and pretty scary looking.” No existing LAA closure device was big enough to close off his ostium.
