The aim of this study was to clarify the characteristics and ablation outcomes of atrial tachyarrhythmias after Maze operation. Methods and Results: Twenty-eight cases who underwent catheter ablation of post-Maze procedure atrial tachyarrhythmia (42 sessions; 1.5 per patient) in our 5 teaching affiliate hospitals were retrospectively analyzed. Cox-Ⅳ Maze procedure and left atrial Maze were performed in 19 cases and 5 cases, respectively. Mean interval between the surgery and index ablation was 62.4 months. In total, 46 atrial tachyarrhythmias were studied. Reentrant atrial tachycardia (AT) was the most common form (n=36), whereas 4 atrial fibrillation (AF) and 2 focal AT were also observed. Identified tachyarrhythmia circuits were as follows; 16 peri-mitral, 9 left atrial localized reentry (4 septal, 3 posterior, 1 left atrial appendage, 1 anterior), 6 right atrial lateral incision-related, 5 cavo-tricuspid isthmus dependent, 3 roof dependent, 2 right atrial localized reentry (1 coronary sinus, 1 cavo-tricuspid isthmus), 1 bi-atrial reentry, 1 pulmonary vein-left atrial reentrant tachycardia, 2 focal AT (1 para-hisian, 1 coronary sinus), and 1 atrio-ventricular nodal reentry. Termination of targeted tachyarrhythmia was achieved in 34 sessions (81%). AT/AF recurrence free rate at 12, 24, 36 months of follow-up were 91.8%, 81.6%, and 65.3%, respectively. Seven cases underwent multiple sessions (two 2 nd sessions, three 3 rd sessions, and two 4 th sessions). In these cases, de-novo atrial tachyarrhythmias were detected in the repeat procedures. Conclusions: Most of the atrial tachyarrhythmias after Maze operation were incision/gap-related reentrant ATs, among which peri-mitral AT and LA localized reentry were the most prevalent. Although these challenging tachyarrhythmias can be treated with the contemporary mapping techniques, de-novo tachyarrhythmias can emerge in a remote period.
