It is intended to evaluate, in patients with atrial fibrillation (AF), the expression of miRNAs in plasma, their clinical repercussion and their prognostic factor. Materials and Methods: PubMed, Cochrane and Google Scholar platforms were used as a data source. Eligibility criteria: miRNAs as direct biomarkers in the clinical expression of AF; all languages. Last search: 19/09/2019; studies involving other comorbidities were excluded; pharmacological focus; in animals, in patients already submitted to cardiac procedures and review articles. Plasma collection and storage, RNA isolation, data analysis, realtime PCR, miRNA target prediction and statistical analysis were performed in the studies. Results: The studies generated n = 332 patients: with AF and control group. In patients with AF there was an increase in the expression of miR-1266, miR-4279, miR- 892a, miR-3149, miR-155, miR-146b5p, miR-19b and a reduction in miR-3171, miR-3664-5p and miRNA -150. Discussion: it was noted that the regulation of inflammatory mediators, ion channels and cardiac morphophysiology are related to the expression of miRNA. Conclusion: Therefore, the levels of changes in miRNAs may reflect the severity of the clinical and pathophysiological progression of AF, and can be used as predictors of AF.","PeriodicalId":33934,"journal":{"name":"Journal of Cardiac Arrhythmias","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42941389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the use of antiarrhythmics, it is difficult to control clinically, causing symptoms and mainly generating risk of a thromboembolic event. Since 1998, by means of radiofrequency ablation, the treatment of atrial fibrillation has completely changed, but together with this important evolution complications from this ablative treatment technique have also started. In addition to the pulmonary vein stenosis caused by the ablation and later corrected with the change in the technique, atrioesophageal fistulas appeared due to the application of radiofrequency in the posterior wall of the left atrium. This wall is very close (0.5 cm onaverage) to the esophagus, which facilitates the formation of the fistula that leads to the death of almost 100% of the affected patients, despite the various treatment measurements already developed. To avoid this serious complication, several authors have created techniques to protect the esophagus including its mechanical deviation to a region opposite to the radiofrequency application, taking advantage of its mobility and easiness of handling. The mechanical deviation of the esophagus has proven to be the simplest, cheapest and most efficient way to protect this organ from radiofrequency thermal damage during atrial fibrillation ablation.","PeriodicalId":33934,"journal":{"name":"Journal of Cardiac Arrhythmias","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46253738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The malignant cardioinhibitory form is caused by abrupt and intense vagal reflex with or without defined triggers. Refractory cases to preventive measures and pharmacological handling has been treated with definitive pacemaker implantation. Besides showing questionable results, pacemaker implantation is highly rejected by young patients. In the late 1990s, we proposed specific vagal denervation by catheter ablation and spectral mapping, for paroxysmal AF, functional bradyarrhythmias and severe cases of malignant cardioinhibitory syncope giving rise to cardioneuroablation. Recently, many authors worldwide have been reproducing the cardioneuroablation results where elimination or significant reduction of the vagal response were observed, which abolished symptoms in more than 75% of patients followed up to 14 years, without complications. Therefore, cardioneuroablation has shown to be a real therapeutic option in malignant syncope cardioinhibitory and in any exclusive vagal mediated bradyarrhythmia without the need for pacemaker implantation.","PeriodicalId":33934,"journal":{"name":"Journal of Cardiac Arrhythmias","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45527290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increase in life expectancy that brought a substantial increase in its prevalence in the general population1 implied a marked deepening in the understanding of its electrophysiological mechanisms, in the identification of determining factors or potentiation of its occurrence and obviously in the development of effective strategies of treatment and prevention of its complications. Since the classic study of Wijffels et al., published in 1995 (Atrial Fibrillation Begets Atrial Fibrillation)2 which experimentally demonstrated that atrial frequencies artificially imposed to the atrial myocardium imply marked electrophysiological changes determining the very occurrence of atrial fibrillation, it became clear that once arrhythmia is initiated it potentiates its own occurrence and a constant process of feedback, whose final outcome over time is the installation of arrhythmia in a permanent form. However, for atrial fibrillation to occur, the presence of an adequate electrophysiological environment is necessary, consequent to the presence of several elements that aggress the atrial myocardium under the electrical and structural aspects.","PeriodicalId":33934,"journal":{"name":"Journal of Cardiac Arrhythmias","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47550124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
