A modified surgical ablation line for atrial fibrillation. The Bachmann line.

Surgical treatment of atrial fibrillation generally consists in the isolation of the pulmonary veins ("box-lesion"). Bachmann's bundle is a cardiac structure that may play an important role in the genesis of the atrial fibrillation. Surgical isolation of such bundle has not been reported before. We aim to describe how to perform minimally invasive epicardial pulmonary vein isolation along with the isolation of the Bachmann's bundle. Adding the surgical ablation line of Bachmann's bundle is a feasible, fast, and easy procedure that may be contribute to the reduction of atrial fibrillation relapses.
