With the increase in the aging population, the number of patients with AF has been increasing. Catheter ablation has become a widely used treatment for AF, with pulmonary vein (PV) isolation (PVI) being the standard approach. As the technologies of ablation advance, complete PVI can be achieved within a shorter procedure time. In radiofrequency catheter ablation, lesion size markers incorporating contact force, radiofrequency application power, and radiofrequency application time enable the operator to create PVI lesions efficiently. Cryoballoon ablation is another technology that allows PVI more easily. Pulsed-field ablation is a new technology that accomplishes PVI without causing collateral organ damage and PV stenosis. With the progress of these ablation technologies, many operators have streamlined the procedure workflow to reduce procedure time and minimize procedure-related complications. Internal jugular vein puncture has been performed to advance the electrode catheter into the coronary sinus (CS) to evaluate the anatomy of the CS, record the left atrial and CS potentials, and perform cardioversion to convert AF to sinus rhythm with the use of specific intracardiac defibrillation catheters (ICDC). However, with the advancement of ablation technologies, some operators insert the electrode catheter into the CS via the femoral vein and inferior vena cava (IVC) instead of the internal jugular vein and superior vena cava (SVC) to avoid internal jugular vein puncture, which has some risk of complications, including vascular injury, hematoma, and pneumothorax, and simplify the workflow. BeeAT via IVC approach (Japan Lifeline, Tokyo) is an ICDC designed to insert the electrode catheter into the CS via the IVC. In performing cardioversion, the operator is recommended to insert the distal part of electrodes in the CS and locate the proximal part in the right atrium (RA), forming an alpha-loop configuration (CS/RA configuration). The operator sometimes needs to insert the distal part into the CS deeply to position the proximal part in the RA. However, inserting the distal part deeply into the CS to make an alpha-loop configuration is difficult in some patients because of variations in the location and configuration of the CS ostium. Moreover, unintentional insertion of the distal part of electrodes into the branch of the CS may result in venous perforation and cardiac tamponade. Thus, placement of the ICDC in the CS and RA is sometimes challenging and time-consuming, needs extra fluoroscopy, and causes a risk of CS perforation.</p><p>Ohashi et al. studied the efficacy of the new ICDC configuration in performing cardioversion by evaluating 81 patients undergoing cardioversion with ICDC during the AF ablation procedure.<span><sup>1</sup></span> They initially evaluated the ICDC configuration, inserting the distal part of electrodes in CS and locating the proxi","PeriodicalId":15174,"journal":{"name":"Journal of Arrhythmia","volume":"41 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/joa3.70066","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
