Controversies in Brugada syndrome

Abstract

The Brugada syndrome is an inherited channelopathy associated with increased risk of ventricular arrhythmias and sudden death, often occurring during sleep or resting conditions. Although this entity has been described more than 20 years ago, it remains one of the most debated among channelopathies, with several open questions on its genetic substrate, arrhythmia mechanisms, and clinical management. Studies on the genetics and physiopathology bases of the Brugada syndrome have opened novel investigative pathways and concepts that are now entering the field of cardiovascular genetics and are applied to other inherited arrhythmias. In this perspective, Brugada syndrome can be seen as an example on how basic science discoveries have influenced clinical management and led to novel therapeutic approaches.
