Brief summary
This retrospective single-centre study aims to examine the success rate of concomitant surgical ablation in patients with atrial fibrillation (AF) with an up to eight years follow-up period. Moreover, the focus of this study was to identify variables which predict freedom from AF, such as the type of AF, lesion set performed, energy source used and the patient's characteristics.
Interventions
PROCEDURESurgical Ablation for Atrial Fibrillation
Surgical ablation in combination with other cardiac procedures through a median sternotomy or thoracotomy. Main procedures were valve surgery (i.e. repair, replacement) and/or coronary artery bypass grafting (CABG). Surgical ablation procedures for atrial fibrillation were divided into three different groups according to Heart Rhythm Society (HRS) expert consensus 2017: (1) Pulmonary vein isolation alone; (2) Pulmonary vein isolation combined with left atrial lesion sets; (3) and biatrial procedure.
