Background: Electrical cardioversion (ECV) often is required for terminating recurrent atrial fibrillation (AF) after surgical radiofrequency ablation in patients undergoing mitral valve surgery. However, ECV is unsuccessful in some cases. In this study, we aimed to identify possible predictors of failed ECV for recurrent atrial fibrillation following mitral valve surgery with concomitant radiofrequency ablation. Methods: We enrolled 1,136 persistent AF patients with history of mitral valve surgery and concomitant radiofrequency ablation. Three-hundred-nineteen patients experienced recurrence of persistent AF and received ECV therapy. Comparison was made between patients with failed ECV (Failure group, N = 68) and successful ECV (Success group, N = 251). Results: In multivariate regression analysis, age, pre-ECV loading-dose amiodarone, left atrial diameter, atrial flutter and time from surgery to ECV were independent predictors for outcomes of ECV. According to receiver operating characteristic curve analysis, the best threshold values of age, left atrial diameter and time from surgery to ECV for predicting failed ECV were 55.5 years, 64.5 mm, and 90.5 days, respectively. Conclusion: Older age, larger left atrium and longer time from surgery to ECV are independent predictors for failed ECV in this group. Compared with AF, atrial flutter is easier to be successfully terminated by ECV. Pre-ECV loading-dose amiodarone is helpful for successful ECV. These findings have important implications for identifying the kinds of patients to receive effective ECV.

Aim. To examine an opportunity of sinus rhythm recovery in patients with mitral valve disease and atrial fibrillation (AF) by the means of surgery and concomitant procedures. Methods. 180 patients with AF who underwent mitral valve surgery using cardiopulmonary bypass in 2007-2011 were examined. Patients’ mean age was 52.5±0.5 years, 71 (39.4%) were male, 109 (60.6%) - female. Patients were divided into 3 groups: 22 patients with paroxysmal AF were included in Group I. 109 patients with persistent AF who underwent mitral valve surgery only were allocated to the Group II. 49 patients with persistent AF who underwent additional pulmonary vein isolation (radiofrequency ablation) were included in the Group III. Results. 83 (46.1%) of patients had single mitral valve disease, 62 (34.4%) of patients had multiple valve disease with involvement of tricuspid valve, 21 (11.7%) of patients had multiple valve disease with involvement of aortic valve, 21 (11.7%) of patients had all abovementioned valves involved. Mean arrhythmia duration was 36.3±3.8 months. Sinus rhythm was restored during the surgery in 16 (72.7%) patients of the Group I, in 60 (55.0%) patients of the Group II, in 41 (83.7%) patients of the Group III. Sinus rhythm was still registered at the discharge in 14 (63.6%), 19 (17.4%) and 13 (26.5%) respectively. Conclusion. It is possible to recover and hold regular rhythm in early postoperative period in more than 60% of cases in patients who underwent surgery for mitral valve disease and concomitant paroxysmal AF. Simultaneous radiofrequency ablation performed in patients with persistent AF increases sinus rhythm recovery rate in first day after surgery.

Background. Atrial fibrillation surgical radiofrequency ablation (AFSA) during mitral valve surgery (MVS) has almost completely superseded the Cox-Maze procedure for the treatment of atrial fibrillation. Methods. We retrospectively analyzed 100 patients who underwent MVS + AFSA in our institution from January 2008 to June 2017. We compared the effectiveness of AFSA in patients who underwent LAA exclusion to those who did not. Moreover, we analyzed the role of preoperative AF duration (≤ or >1 year) and medial-lateral left atrial dimensions (ML-LAD) (≤ or >6 cm). The efficacy endpoint was freedom from AF at discharge and at 2-year follow-up. The safety endpoints were need of a permanent pacemaker (PMK), surgical re-exploration, occurrence of stroke, and left circumflex artery or esophageal lesions. Results. Overall, the rate of AF freedom was 69% at discharge and 80% at 2-year follow-up. LAA exclusion did not influence AF freedom at 2-year follow-up, and 84.6% of patients who underwent LAA exclusion were in the sinus rythm (SR) at 2 year compared to 75% of those who did not receive LAA exclusion free from AF as well ( p = 0.230 ). AF duration ≤1 or >1 year did not influence sinus rhythm (SR) maintenance (85.7% vs. 75.8%; p = 0.224 ), and in these two groups, LAA exclusion did not change the efficacy of AFSA. ML-LAD ≤ 6 cm was associated with better results in terms of SR maintenance. A statistically significant association between LAA exclusion and SR maintenance at 2-year follow-up ( p = 0.017 ) was found among patients with ML-LAD ≤ 6 cm. Complications included 7 cases of PMK implantation, 2 cases of surgical re-exploration, and 1 case of stroke. No circumflex artery or esophageal lesions occurred after surgical procedures. Conclusions. In our experience, AFSA during isolated MVS resulted in good outcomes in terms of SR maintenance and incidence of complications. AF duration ≤ 1 year did not influence results, while patients with ML-LAD ≤ 6 cm had significantly better results regarding SR at follow-up. In patients with ML-LAD ≤ 6 cm, LAA exclusion significantly increased the success rate of SR maintenance at 2-year follow-up.
