The Western Atrial Fibrillation Symposium is a comprehensive education meeting focused exclusively on atrial fibrillation. The conference features distinguished faculty and physicians from eight countries and 20 renowned clinical and research centers across the United States.The symposium has grown greatly since it's origination in 2007. This year's symposium hosted over 300 scientists from around the world.
