Transthoracic echocardiography is widely used for imaging, especially for preprocedural assessment, while transesophageal and intracardiac echocardiography (ICE) are used for intraprocedural guidance during transseptal puncture. Cardiac MDCT, leveraging its high spatial resolution, offers a detailed anatomical visualization of cardiac chambers and adjacent structures; moreover, left atrial wall thickness assessed by MDCT may guide radiofrequency energy titration to enhance procedural safety and efficiency. At the same time, CMR allows for detailed myocardial tissue characterization and the detection of fibrosis. ICE, MDCT, and CMR also permit intra-procedural image integration with electroanatomical maps, allowing to be aware of a greater amount of intra-procedural real-time information regarding the anatomy and the local characteristics of the tissue in contact with the ablation catheter. One of the primary objectives of performing CI-aided AF ablations is to increase procedural safety and to permit more personalized procedures, according to the characteristics of each patient. This review offers a comprehensive overview of the current applications of CI during the different phases of AF ablation and explores the potential future applications of CI in this context.</p>","PeriodicalId":16202,"journal":{"name":"Journal of Interventional Cardiac Electrophysiology","volume":" ","pages":"1719-1738"},"PeriodicalIF":2.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803624","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}
