Role of comprehensive posterior ablation in AF

Mechanisms for atrial fibrillation (AF) - rotors, GPs, ectopic foci, reentrant circuits - have a common origin on the posterior left atrium. No matter which theory for the initiation of AF you subscribe to, the posterior wall is a clear ablation target for addressing AF substrates. Recent enhanced MRI studies demonstrate that there is a progression of fibrosis and AF along the heart's posterior.

A new theory posits that areas of high mechanical stress along the pericardial reflections lead to atrial stretch and remodeling, creating conditions for AF along the posterior. Watch this new video to learn more about the role of comprehensive posterior ablation in AF.
