国际专家共议人工心脏关键技术定义，为中国企业出海提供机遇

Core Viewpoint - The 31st International Society for Mechanical Circulatory Support (ISMCS) annual meeting in Vienna focused on advancements in rotary blood pumps and related mechanical circulatory support systems, emphasizing the need for standardized terminology and definitions in the industry [1][3]. Group 1: Industry Developments - The meeting featured experts from multiple countries discussing the core topic of "Understanding Bearing Technologies in Contemporary Durable Rotary Blood Pumps," aiming to clarify concepts and unify terminology in artificial heart bearing technology [3][4]. - Heart failure, often referred to as the "cancer" of the cardiovascular field, affects over 60 million people globally, with a 50% five-year mortality rate upon diagnosis, comparable to that of malignant tumors [3][4]. Group 2: Challenges and Solutions - The lack of standardized terminology and clear definitions has hindered effective communication among industry experts, researchers, and clinicians, impacting the accurate understanding and evaluation of product performance [4]. - The conference underscored the importance of establishing a unified and scientific classification framework for bearing technologies, which could serve as a basis for future industry white papers and regulatory assessments [4][5]. Group 3: Key Contributions - Dr. Marvin Slepian, former president of the American Society for Artificial Internal Organs (ASAIO) and ISMCS, highlighted the need for clear technical definitions and industry consensus to promote healthy industry development [5]. - Dr. Chen Chen from Suzhou Tongxin Medical presented on the stability of magnetic and hydrodynamic bearings in blood pumps, emphasizing the critical relationship between bearing stability and blood damage, using the BrioVAD as a case study [5].
