Results The consensus panel agreed on the following statements in patients with AF undergoing cardiac surgery concomitant surgical ablation : 1 .
Improves the achievement of sinus rhythm at discharge and 1 year ( level A ) ; this effect is sustained up to 5 years ( level B ) .
2 .
3 .
Does not increase the risk of perioperative mortality ( level A ) , stroke ( level A ) , myocardial infa rct ion ( level B ) , cardiac tamponade ( level A ) , reoperative bleeding ( level A ) , esophageal injury ( level B ) , low cardiac output ( level A ) , intraaortic balloon ( level B ) , congestive heart failure ( level B ) , ejection fraction ( EF ; level B ) , pleural effusion ( level A ) , pneumonia ( level A ) , renal dysfunction ( level B ) , and mediastinitis ( level A ) .
The incidence of esophageal injury remains to be low ( level B ) .
4 .
Does not reduce mortality at 1 year ( level A ) .
5 .
6 .
Increases cardiopulmonary bypass and cross-clamp times ( level A ) , with no difference in intensive care unit and hospital length of stay ( level A ) .
Conclusions Given these evidence -based statements , the consensus panel stated that , in patients with persistent and permanent AF undergoing cardiac surgery , concomitant surgical ablation is recommended to increase incidence of sinus rhythm at short- and long-term follow-up ( class 1 , level A ) ; to reduce the risk of stroke and thromboembolic events ( class 2a , level B ) ; to improve EF ( class 2a , level A ) ; and to exercise tolerance ( class 2a , level A ) and long-term survival ( class 2a , level B )
Objective This purpose of this consensus conference was to determine whether surgical atrial fibrillation ( AF ) ablation during cardiac surgery improves clinical and re source outcomes compared with cardiac surgery alone in adults undergoing cardiac surgery for valve or coronary artery bypass grafting .
Saline-irrigated, cooled-tip radiofrequency ablation is an effective technique to perform the maze procedure.
BACKGROUND We evaluated the effectiveness of the saline-irrigated-cooled-tip-radiofrequency ablation ( SICTRA ) to produce linear intraatrial lesions . METHODS Thirty patients with chronic atrial fibrillation and mitral valve disease were consecutively r and omized to have mitral valve operation either with a Maze procedure ( group A ) or without ( group B ) . Intraatrial linear lesions were made with an SICTRA catheter ( 20 to 32 W ; 200 to 320 mL/h saline ) . An  echocardiography and 24-hour electrocardiogram  were obtained 12 months postoperatively . RESULTS The cumulative frequencies of sinus rhythm in group A and B were 0.80 and 0.27 ( p < 0.01 ) . Restored biatrial contraction was present in 66.7 % ( 6 of 9 ) of the group A patients in sinus rhythm . One patient from each group received a permanent pacemaker because of bradycardia . A fatal renal bleeding and mediastinitis occurred in 2 group A patients , 6 weeks postoperatively . One group A patient had sudden cardiac death at home , 4 months after operation . One patient from each group had lethal respiratory failure , 7 and 10 months after operation . Survival after 12 months for group A and B was 73 % and 93 % ( p = 0.131 ) . CONCLUSIONS The SICTRA appeared to be an effective technique to perform the Maze procedure
