The results of epicardial radiofrequency ablation of anatomic zone ganglionic plexi of the left atrium during CABG of patients with coronary heart disease and atrial fibrillation are analyzed. From 2009 to 2012 RF ablation procedure was performed in 92 patients with atrial fibrillation and coronary artery disease. Depending on the form of AF the patients were randomized into three groups. The mean follow-up was 14.49.6 months (from 3 до 36 months). Freedom from AF during 24 months after surgery was 78.6% for patients with paroxysmal AF, 42.5% for patients with persistent AF and 39% for patients with long-term persistent AF.

Background. Pulmonary vein isolation is commonly performed using radiofrequency energy with cryoablation gaining acceptance. We performed a meta-analysis of randomized controlled trials which compared radiofrequency versus cryoablation for patients with atrial fibrillation. Methods. A systematic search strategy identified both published and unpublished articles from inception to November 10, 2016, in multiple databases. The primary outcomes for this meta-analysis were long-term freedom from atrial fibrillation at 12-month follow-up and overall postoperative complication rates. For all included studies, the methodological quality was assessed through the Cochrane Collaboration’s tool for risk of bias. Results. A total of 247 articles were identified with eight being included in this review as they satisfied the prespecified inclusion criteria. Overall, there was no significant difference in freedom from atrial fibrillation at ≥12-month follow-up between those receiving cryoballoon and radiofrequency ablation, respectively (OR = 0.98, CI = 0.67–1.43, I2 = 56%, p=0.90). Additionally, the secondary outcomes of duration of ablation, fluoroscopy time, and ablation time failed to reach significance. Cryoballoon ablation had significantly greater odds of postoperative phrenic nerve injury at 12-month follow-up. Conclusions. Our meta-analysis suggests that cryoballoon ablation provides comparable benefits with regard to freedom from atrial fibrillation at medium-term follow-up, fluoroscopy time, ablation time, operative duration, and overall complication rate in comparison to radiofrequency ablation.

Abstract Objective to compare the efficacy of radiofrequency ablation (RFA) and drug therapy in patients with atrial fibrillation (AFib) and heart failure (HF) within 12-month follow-up. Materials and methods 130 patients (men-75%, average age-62.8 ± 11.8 years) with AFib and HF with left ventricular ejection fraction (LVEF)<50% were included in a prospective study. In 107 (82%) of the included patients, intermediate LVEF was detected (40-49%). At the time of inclusion, paroxysmal AFib (PaAFib) was recorded in 60 (46%) of patients and persistent AFib (PeAFib) in 70 (54%). AFib RFA was performed in 65 patients, 65 patients continued to receive optimal antiarrhythmic therapy. Prior to the intervention and after 12 months, all patients underwent transthoracic echocardiography and quality of life (QoL) assessment using the SF-36 questionnaire. Results the freedom from AFib within 12 months follow-up period was registred in 49 (75%) of patients in the RFA group and 26 (40%) in the drug therapy group. After 12 month follow-up period we revealed increase of LVEF (p < 0.001), decrease of anteroposterior size (p <0.001) and volume (p < 0.001) of left atrium (LA), improvement of mental (p = 0.008) and physical (p = 0.048) health components according to the SF-36 questionnaire in the RFA group. In the group of drug rhythm control, after 12 months there was only the improvement of mental (p = 0.006) and physical p = 0.016) health components and it was much less than in RFA group (р<0.001). Similar results were received in patients who were free from Afib within 12 months in both groups. Conclusions in patients with AFib and HF with LVEF < 50%, restoration and maintenance of sinus rhythm using RFA was accompanied by an increase in LVEF, decrease of  LA size, and an improvement of QoL. In the group of drug therapy, there was a lower freedom from AFib and there was the slight improvement only in QoL.

Abstract Aims The aim of the study was to determine the incidence of oesophageal lesions after radiofrequency ablation (RFA) of atrial fibrillation (AF) with or without the use of oesophageal temperature probes. Methods and results Two hundred patients were prospectively randomized into two groups: the OPERA+ group underwent RFA using oesophageal probes (SensiTherm™); the OPERA− group received RFA using fixed energy levels of 25 W at the posterior wall without an oesophageal probe. All patients underwent post-interventional endoscopy and Holter-electrocardiogram after 6 months. (Clinical.Trials.gov: NCT03246594). One hundred patients were randomized in OPERA+ and 100 patients in OPERA−. The drop-out rate was 10%. In total, 18/180 (10%) patients developed endoscopically diagnosed oesophageal lesions (EDEL). There was no difference between the groups with 10/90 (11%) EDEL in OPERA+ vs. 8/90 (9%) in OPERA− (P = 0.62). Despite the higher power delivered at the posterior wall in OPERA+ [28 ± 4 vs. 25 ± 2 W (P = 0.001)], the average EDEL size was equal [5.7 ± 2.6 vs. 4.5 ± 1.7 mm (P = 0.38)]. The peak temperature did not correlate with EDEL size. During follow-up, no patient died. Only one patient in OPERA− required a specific therapy for treatment of the lesion. Cumulative AF recurrence after 6 (3–13) months was 28/87 (32%) vs. 34/88 (39%), P = 0.541. Conclusion This first randomized study demonstrates that intraoesophageal temperature monitoring using the SensiTherm™ probe does not affect the probability of developing EDEL. The peak temperature measured by the thermoprobe seems not to correlate with the incidence of EDEL. Empiric energy reduction at the posterior wall did not affect the efficacy of the procedure.

Abstract Background The monocyte/high-density lipoprotein ratio (MHR) has emerged as a promising alternative biomarker in the fields of cardiovascular disease and atrial fibrillation (AF). This retrospective study was aimed to explore the predictive value of the MHR for the late recurrence of AF after radiofrequency ablation. Methods From April 2015 to October 2018, patients with paroxysmal AF who had undergone radiofrequency catheter ablation at Subei People’s Hospital of Jiangsu Province were enrolled in our study. All the participants were observed until November 2019 after the procedure. During the postoperative follow up, the patients were categorized into the recurrence group and maintenance of sinus rhythm group based on who had experienced AF recurrence. Results One hundred twenty-five patients were diagnosed with paroxysmal AF, with an average age of 61.2 ± 9.3 years. Forty-seven patients had developed late recurrence during a mean follow up of 25.1 ± 12.0 months. The AF recurrence event rates were significantly increased in the highest MHR tertile compared with those in the lowest MHR tertile (22.0% vs. 57.1%; P < 0.05). On multivariate logistic regression analysis, the preablation MHR (OR = 1.34; 95% CI = 1.12 ~ 1.60; P = 0.001) and left atrial diameter (LAD) (OR = 1.21, 95% CI = 1.08 ~ 1.35; P = 0.001) were independent risk factors predicting the recurrence of AF after radiofrequency ablation. Furthermore, receiver operating characteristic (ROC) curve analysis revealed that the area under the curve (AUC) of the MHR was 0.712 (95% CI = 0.618 ~ 0.806; P = 0.000) and that of LAD was 0.739 (95% CI = 0.653 ~ 0.814; P = 0.000). Z-test found no significant difference between the MHR and LAD regarding the AUC (Z = 0.451; P = 0.652). Conclusion An elevated preablation MHR was associated with an increased risk of the postoperative recurrence of AF. Additionally, the MHR independently predicted the late recurrence of paroxysmal AF after radiofrequency ablation, with the same predictive value as LAD.
