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.

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 Atrial fibrillation surgical radiofrequency ablation (AFSA) during mitral valve surgery (MVS) has almost completely superseded the Cox-Maze procedure for the treatment of atrial fibrillation.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.

Abstract Background Ablation devices are being utilized in surgical procedures treating atrial fibrillation. Few studies seek to define a cut-off value for left atrial diameter size beyond which risks of procedure outweigh chance of sinus recovery. This study aims to identify a cut-off value for pre-operative left atrial diameter to assess the efficacy of surgical radio-frequency ablation for treatment of chronic atrial fibrillation in patients undergoing mitral valve surgery. Methods A prospective 6-month follow-up cohort study was done, in which 40 patients were recruited during the period from May 2016 till April 2018. All patients had rheumatic mitral valve disease and permanent atrial fibrillation. Receiver operator characteristic (ROC) curves were used to calculate the area under the curve and cut-off value for left atrial diameter. The efficacy of the overall survival time was estimated using the Kaplan-Meier method. Results Pre-operatively left atrial diameter of > 59 mm was significantly associated with decrease in the possibility of reverting to sinus rhythm after surgery (OR 0.292, p-value = 0.001). The cut-off value for left atrial diameter was 59mm (sensitivity = 93.3%, specificity = 96.1%). Kaplan-Meier survival estimates were 175.07 days (156.3 - 193.9) for patients with left atrial diameter < 59mm and 62.64 days (26.6-98.7) for patients with left atrial diameter > 59mm. Conclusion In patients undergoing mitral valve surgery, higher degrees of ablation success are associated with smaller left atrial diameter in terms of conservation of the sinus rhythm post operatively.
