Tratamento operatório da fibrila？？o atrial: revis？o integrativa da literatura

when atrial fibrillation (af) is present in pre-operative open heart surgeries, including coronary artery bypass grafting and valve operations, it represents an independent risk factor for cardiac events and reduced survival. due to the complexity of the subject, especially when evaluating success rates (reversion and maintenance of normal sinus rhythm), a consensus statement was recently proposed by the international society of minimally invasive cardiothoracic surgery (ismics), in order to determine whether the intraoperative ablation of af promotes favorable clinical outcomes in patients undergoing other cardiac operations in comparison with individual operations without ablation. the aim of this paper is to present published data which has contributed to consensus statement and can be useful as update source. the integrative review was the methodology that provides synthesis of knowledge and applicability of results of significant studies about presented topic
