To promote the clinical standardization of TEER technology and deeply decode the technical details and full lifecycle management of TEER, Valgen Medtech has specially planned the TEER China Tour · Master's Intensive Seminar. The seminar focuses on three topics: FMR patient management, intraoperative strategies for TEER, and the opportunities and challenges of dual-valve TEER. This academic conference features a gathering of top experts and offers brilliant highlights.

At the beginning of the meeting,Wang Jian'an, Academician of the Second Affiliated Hospital of Zhejiang University School of MedicineHe delivered a speech, pointing out that China's TEER technology requires both deep cultivation and long-term planning for growth. He expressed hope that this conference would build consensus, address clinical pain points, and explore innovative pathways.

Professor Chen Xiaomin from Ningbo First Hospital, Professor Ma Genshan from Zhongda Hospital Affiliated to Southeast University, Professor Zhou Daxin from Zhongshan Hospital Affiliated to Fudan UniversityServe as the moderator for this session;Professor Chen Tao from the Second Affiliated Hospital of Harbin Medical University, Professor Li Yan from Tangdu Hospital of Air Force Medical University, Professor Zhang Haibo from Beijing Anzhen Hospital affiliated to Capital Medical UniversityAttend the roundtable discussion, with frequent insightful remarks and stimulating ideas.

Professor Liu Xianbao from the Second Affiliated Hospital of Zhejiang University School of MedicineAnalysisExperience in FMR Patient Management and Treatment.He emphasized that FMR disease is secondary and progressive, which determines that the treatment of FMR cannot be one-dimensional. Instead, it requires us to conduct a comprehensive evaluation and consideration based on the actual situation of the patient, and ultimately formulate a complete treatment plan. We must maintain our original intention and serve more patients well.

Professor Hao Zhou from the First Affiliated Hospital of Wenzhou Medical UniversityFrom multiple perspectives, a deep analysis was conducted, combined with evidence-based proof. Together with the attending experts, a broader understanding of the FMR disease was reorganized. At the end of the speech, Professor Zhou Hao shared a research study on utilizing AI for patient data analysis. He pointed out that in the future, we should also make good use of cutting-edge technologies such as big data and artificial intelligence to analyze the most suitable solutions for the most appropriate patients.

Professor Feicheng Yu from Sir Run Run Shaw Hospital, School of Medicine, Zhejiang UniversityLatest Advances in AFMR: As the most recently recognized subtype in FMR disease, there is no consensus yet in academia on the definition, causes, and clinical pathways of AFMR. Professor Yu Feicheng, drawing from the latest research, clarified that TEER can benefit AFMR patients. He also introduced approaches to the management and treatment of AFMR patients based on his clinical experience. The future calls for more clinical studies to provide stronger evidence-based support for clinical practice.

Professor Xiaodong Zhuang from the First Affiliated Hospital of Sun Yat-sen UniversityIn-depth Analysis of "ComplexTreatment Strategies for FMR Patients》, combining clinical case practice with detailed theoretical evidence, provides corresponding strategies and operational techniques for different patient types. As a TEER operator, one should not only refine surgical operation skills but also deeply explore the underlying principles to be able to apply knowledge across situations and quickly progress through the learning curve.

Professor Ye Honghua from Li Huili Hospital, Ningbo Medical CenterServe as the moderator for this session;Professor Feng Zhao from Tianjin Chest Hospital, Professor Pengyi He from the Fifth Affiliated Hospital of Xinjiang Medical UniversityAttend the roundtable discussion,Focusing on the细微之处, an In-depth Discussion on Decision-making and Clinical Application during TEER Procedures.

Professor Zhang Xinmin from Professor Wu Lianpin's team at the Second Affiliated Hospital of Wenzhou Medical UniversityShare"Stable Control with Precision"·Strategies and Techniques in TEER Procedures》. Through case studies, he shared insights on clip selection: the consideration for clip selection is not one-dimensional; a comprehensive assessment of the patient's anatomy should be conducted, taking various factors into account. Additionally, he discussed how to utilize the unique scaled operating system of the DragonFly™ device, produced by Valgen Medtech Co., Ltd., to contribute to the success of the surgery.

Professor Guipeng An from Qilu Hospital of Shandong UniversityBringing the Lecture Topic: "Persistence in Balance: The Art of Balance in TEER Procedures》, using clinical cases as an introduction,In the face of complex clinical scenarios such as high transvalvular pressure gradients and high leaflet tension, how to achieve the perfect balance between the safety and efficacy of the therapy through skillful operation and full utilization of device functionality.

Professor Peng Xiaoping from the First Affiliated Hospital of Nanchang University, Professor Song Guangyuan from Beijing Anzhen Hospital affiliated to Capital Medical University, Professor Zhang Junjie from Nanjing First HospitalServe as the moderator for this session;Professor Haojian Dong from Guangdong Provincial People's Hospital, Professor Zhenfei Fang from the Second Xiangya Hospital of Central South University, Professor Fei Ma from Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, and Professor Kai Xu from the General Hospital of Northern Theater CommandAttendees of the Roundtable DiscussionDrawing from their own rich clinical experience, they provided profound insights and thorough analyses. The collision of academic perspectives and the sparking of inspiration at the scene pushed the academic atmosphere of this symposium to its peak.

Professor Song Sixian from Taipei Veterans General HospitalStarting from his own rich experience in TEER treatment for mitral and tricuspid valves, he shared "My Experience with Dual-Valve TEER Application." Combining the latest evidence-based findings, he thoroughly analyzed the mutual influence of mitral and tricuspid regurgitation and the key points of collaborative treatment, providing valuable diagnostic insights and treatment strategies for a wide range of clinical experts. His speech also sparked a heated discussion among the experts present.

Professor Chaoxia Pu from the Second Affiliated Hospital of Zhejiang University School of MedicineFrom the Perspective of Ultrasound: An Introduction to "From Single Valve to Multiple Valves,Opportunities and Challenges of TEER." Due to its unique anatomical features, the tricuspid valve presents greater difficulty in ultrasound guidance. Based on extensive clinical experience, Professor Pu provided unique insights into how to further refine tricuspid valve ultrasound techniques. The emergence of future advanced imaging technologies is also expected to enhance the operability of tricuspid valve TEER.

To actively promote the popularization of TEER technology, at the CHINA VALVE (HANGZHOU) 2025 offline venue, Valgen Medtech has carefully set up an innovative exhibition area. The three-day simulator practical operation sessions were full of excitement, allowing Chinese and foreign participating experts to immerse themselves in experiencing the DragonFly™ Mitral Valve Clip device, with great enthusiasm for learning.
