The enthusiastic participation of attendees brought a high-level academic feast to the venue. This special session was hosted byProfessor Jiang Chenyang from Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Professor Fu Hua from West China Hospital, Sichuan University, Professor Ju Weizhu from Jiangsu Provincial People's Hospital, Professor Wang Yan from Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Professor Zou Cao from the First Affiliated Hospital of Soochow University, and Professor Gui Chun from the First Affiliated Hospital of Guangxi Medical UniversityCo-host.
Professor Ma Changsheng from Beijing Anzhen Hospital, Capital Medical University
At the beginning of the meeting,Professor Ma Changsheng from Beijing Anzhen Hospital, Capital Medical University, delivered the opening speech.He highly praised the milestone significance of the pulsed electric field ablation (PFA) technology and looked forward to its broad application prospects in future clinical practice, setting a far-sighted tone for the entire event.
Professors Hu Hongde, Wu Gang, and Liu Xiongtao respectively shared fascinating cases of treating patients with paroxysmal atrial fibrillation using AccuPulse's variable loop diameter circular PFA catheter.。A systematic and in-depth case analysis was conducted, covering patient conditions, ablation strategies, operational key points, and postoperative summaries. The valuable clinical experience provided highly valuable references for both online and offline operators. The hosting experts engaged in an in-depth discussion around the surgical demonstration, creating a strong academic atmosphere.

InProfessor Hongde Hu from West China Hospital, Sichuan UniversityIn the shared case of paroxysmal atrial fibrillation surgery, the team used AccuPulse's variable-diameter pulsed field ablation catheter to successfully complete the procedure and achieve pulmonary vein isolation (PVI). The patient recovered well post-surgery, demonstrating the convenience and safety of the catheter. Director Hu highlighted the advantages of the variable-diameter circular pulsed field ablation (PFA) catheter in ablating within and at the ostium of the pulmonary veins: “Small circle for entry, large circle for ablation,” which enhances contact and transmural ablation. By utilizing steerable sheaths to support segmental expansion of the circular catheter against the vestibule for ablation, the approach can address paroxysmal atrial fibrillation triggered by non-pulmonary vein foci, thereby increasing surgical success rates. Based on preoperative CT, Director Hu formulated a surgical strategy centered on circumferential pulmonary vein ablation, ensuring thorough and safe intervention within the pulmonary veins and vestibular areas.

Professor Gang Wu from the First People's Hospital of ShanghaiSharing his team's successful use of AccuPulse's circular variable-diameter PFA catheter to perform pulsed field ablation on a 75-year-old patient with paroxysmal atrial fibrillation who had a pacemaker implanted for ten years. This case faced two major clinical challenges: first, the unique anatomical structure of the patient’s right inferior pulmonary vein, which was relatively small and caused difficulty in catheter positioning; second, there is currently no clear consensus on whether the PFA electric field might affect pacemaker function. Prior to the surgery, Professor Wu Gang confirmed the feasibility of the procedure based on the localized electric field characteristics of the PFA catheter. Through meticulous 3D modeling and catheter manipulation, they successfully overcame the positioning difficulties in the right inferior pulmonary vein and ensured the quality of ablation using the catheter's real-time contact-sensing feature. Postoperative results showed complete pulmonary vein isolation, marking the operation as a complete success and perfectly demonstrating the superior performance of AccuPulse's cardiac pulse ablation system under complex anatomical conditions.
Professor Liu Xiongtao from Xianyang Hospital of Yan'an University
This Surgical DemonstrationProfessor Liu Xiongtao from Yan'an University Xianyang HospitalPresented an excellent case of treating paroxysmal atrial fibrillation using pulsed electric field ablation technology through online participation. The surgery achieved complete pulmonary vein isolation, and the patient recovered well post-operation without any complications. The selectable discharge technology ensured ablation efficiency while effectively avoiding excessive discharge, significantly enhancing surgical safety. The variable loop diameter design of the circular catheter can flexibly adapt to the anatomical structures of different pulmonary veins, greatly improving operational efficiency. Professor Liu Xiongtao specifically pointed out that when performing roof ablation with a circular PFA catheter, the key operational point to ensure stable contact and effective ablation is to use a steerable sheath for enhanced support.

The live broadcast and voltage mapping clearly demonstrated the excellent contactability and stability of AccuPulse's circular variable-diameter pulsed field ablation catheter. The surgical procedure was smooth, with immediate success in pulmonary vein isolation, and the patient remained stable. This earned unanimous praise and lively discussion from both the on-site hosting guests and online audience. The operator explicitly pointed out that the variable-diameter design of the PFA catheter, along with its real-time contact indication function, provided a basis for determining ablation points during the procedure, ensuring efficient and safe energy delivery only when optimal contact was achieved.

Based on the sharing and discussion of surgical demonstration cases of the AccuPulse circular variable-diameter pulsed ablation catheter, the attendees reached a consensus on the future development of PFA pulsed electric field ablation technology.Professor Hua Fu from West China Hospital, Sichuan UniversityThe summary indicates that the deep integration of PFA technology with the three-dimensional mapping system is the cornerstone to ensure the precision and safety of the surgery. Secondly, for key anatomical areas such as the anterior wall and the junction of the two pulmonary veins, focused and sufficient ablation should be performed. After ablation, the effect must be verified through rigorous voltage mapping to achieve a 100% pulmonary vein isolation effect. Finally, the experts at the meeting unanimously agreed that the effectiveness of the variable loop circular PFA catheter is also closely related to the operator's experience, requiring the operator to continuously accumulate and optimize operational skills in practice to fully leverage its technical advantages. These consensuses have pointed out a clear direction for the standardized promotion and clinical application of PFA technology.
