Biological valves can lead to structural valve degeneration (SVD) over time and due to various factors, reducing their durability. SVD patients need to undergo valve replacement surgery again, while traditional open chest surgery can cause significant trauma and patients often give up treatment due to intolerance. Research has shown that as an alternative treatment option for reoperation of thoracic valve replacement surgery, redo-transcatheter aortic valve replacement for SVD is safe and effective, but still faces many challenges, including prosthesis-patient mismatch, high cross valve pressure difference, and coronary obstruction. This article aims to review the strategies, clinical research status and progress of redo-transcatheter aortic valve replacement in SVD patients.
In recent years, the field of cardiovascular surgery has undergone revolutionary changes and made rapid progress in various aspects, bringing more hope and possibilities for the health and well-being of patients. As in every era full of change, opportunities and challenges always coexist. The constant emergence of new technologies brings new opportunities and hope, as well as constant challenges to past concepts. This article aims to comprehensively summarize the latest developments in cardiovascular surgery, especially since 2023, introduce cutting-edge knowledge and technologies in the field of cardiovascular surgery, and deeply analyze and explore future development directions, in order to provide useful references and inspirations for cardiovascular doctors and jointly promote the continuous progress of cardiovascular surgery in China.
