1 Influence of Preoperative Atrial Fibrillation on Late Results of Mitral Repair: Is Concomitant Ablation Justified?  Dumbor L. Ngaage, MB, FRCS(C-Th), Hartzell V. Schaff, MD, Charles J. Mullany, MB, MS, Sunni Barnes, PhD, Joseph A. Dearani, MD, Richard C. Daly, MD, Thomas A. Orszulak, MD, Thoralf M.

2 Fig 1 Flow chart of the study patient selection process. The exclusion criteria were history of cardiac arrhythmia other than atrial fibrillation (AF), previous permanent pacemaker and (or) automatic implantable cardioverter defibrillator implantation, permanent neurological deficit from stroke, and residence outside the United States. (SR = sinus rhythm). The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2007 The Society of Thoracic Surgeons Terms and Conditions

4 Fig 3 Survival regression model showing predictors of all-cause late mortality by multivariate analysis. (AF = atrial fibrillation; CHF = congestive heart failure.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2007 The Society of Thoracic Surgeons Terms and Conditions

5 Fig 4 Kaplan-Meier curves showing intervention for heart rhythm-related complications in patients with preoperative atrial fibrillation (Preop AFib) and those in sinus rhythm (Preop SR) after repair of mitral regurgitation.
