1 Right Isthmus Ablation Reduces Supraventricular Arrhythmias After Surgery for Chronic Atrial Fibrillation  Francesco Onorati, MD, Antonio Esposito, MD, Gaetana Messina, MD, Antonio di Virgilio, MD, Attilio Renzulli, MD, PhD  The Annals of Thoracic Surgery  Volume 85, Issue 1, Pages (January 2008) DOI: /j.athoracsur Copyright © 2008 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Left-sided mini-Maze. (LAA = left atrial appendage; LPV = left pulmonary veins; MV = mitral valve; RPV = right pulmonary veins.) The Annals of Thoracic Surgery  , 39-48DOI: ( /j.athoracsur ) Copyright © 2008 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 (A) Cumulative freedom from atrial fibrillation (AF) recurrence. The line indicates survival function, and the tick marks are censored data. (B) Freedom from AF between groups undergoing left + right Maze (gray line) and left-sided Maze (black line). The tick marks indicate censored data. (C) Cumulative freedom from atrial flutter (AFL). The line indicates survival function, and the tick marks are censored data. (D) Freedom from atrial flutter between the left + right Maze (gray line) and left-sided Maze (black line) groups. The tick marks indicate censored data. The Annals of Thoracic Surgery  , 39-48DOI: ( /j.athoracsur ) Copyright © 2008 The Society of Thoracic Surgeons Terms and Conditions

4 Fig 3 (A) Cumulative freedom from congestive heart failure (CHF). The line indicates survival function, and the tick marks are censored data. (B) Freedom from CHF between the between groups undergoing left + right Maze (gray line) and left-sided Maze (black line). The tick marks indicate censored data. (C) Cumulative freedom from hospital readmission. The line indicates survival function, and the tick marks are censored data. (D) Freedom from hospital readmission between the groups undergoing left + right Maze (gray line) and left-sided Maze (black line). The tick marks indicate censored data.

5 Fig 4 (A) Freedom from congestive heart failure CHF (no, grey line; yes, black line) and (B) from hospital readmission (no, grey line; yes, black line) between patients recovering sinus rhythm (SR) and those maintaining atrial fibrillation (AF) at the end of follow-up. The tick marks represent censored data. The Annals of Thoracic Surgery  , 39-48DOI: ( /j.athoracsur ) Copyright © 2008 The Society of Thoracic Surgeons Terms and Conditions
