Cheating death in a maze of surgical ablation data

Published:November 09, 2022DOI:https://doi.org/10.1016/j.hrthm.2022.10.030
      Atrial fibrillation (AF) is encountered in 16%–50% of patients with mitral valve disease and is associated with greater disease severity and mortality with either medical or surgical management of the valve disease.

      In addition to being a marker for disease severity, AF could contribute to adverse outcomes due to systemic emboli, impaired cardiac performance, and risks of AF therapies. Surgical treatment of mitral valve disease combined with a Maze procedure to restore sinus rhythm and removal or occlusion of the left atrial appendage (LAA) can address some of these risks.
