However, the high rate of post-ablation recurrence necessitates the identification of predictors for recurrence risk. Left atrial low-voltage areas (LA-LVASs), reflecting atrial fibrosis, have been confirmed to be related to recurrence of AF. Recently, epicardial adipose tissue (EAT) has been studied due to its role in initiating and maintaining AF. In this study, we try to evaluate the significance of the combined use of left atrial epicardial adipose tissue (LA-EAT) and percentage of LA-LVAs (LA-LVAs%) for predicting the recurrence of AF.</p><p><strong>Methods: </strong>A total of 387 patients with AF who had undergone RFCA for the first time were followed up for 1, 3, 6, and 12 months. They were divided into two groups: the recurrence group (n = 90) and the non-recurrence group (n = 297). Before the ablation, all patients underwent computed tomography angiography examination of the left atrium, and the LA-EAT was measured using medical software (Advantage Workstation 4.6, GE, USA). After circumferential pulmonary vein isolation, a three-dimensional mapping system was used to map the LA endocardium and evaluate the LA-LVAs in sinus rhythm.</p><p><strong>Results: </strong>After a median follow-up of 10.2 months, 90 patients developed AF recurrence after RFCA.

The cardiomyocyte cell populations, derived from the abnormal samples identified through the first-level graph-based analysis, were separated into six distinct cell clusters.</p><p><strong>Conclusion: </strong>Our study provides some information on TOF in a fetus, which can offer a new reference for the early detection and treatment of TOF by comparing defective heart cells with normal heart cells.</p>","PeriodicalId":9391,"journal":{"name":"Cardiology","volume":" ","pages":"221-232"},"PeriodicalIF":1.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141888540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
