| Abstract | Background Transcatheter aortic valve replacement (TAVR) is a growing less invasive surrogate for high-risk patients with aortic valve disease. Although the number of TAVR procedures is growing rapidly, TAVR prosthesis surgical explantation are rare procedures but increasing in frequency. Case presentation We herein presented a case of 68-year-old male who underwent quaternate TAVR bioprostheses implantation. Three months later, his symptoms deteriorated due to aggravated paravalvular leakage and severe mitral regurgitation. A challenging surgical explantation procedure was therefore performed. During the surgery, lethal penetrations of aortic wall due to migration of these devices were found and four bioprostheses were integrally explanted. The native calcified aortic leaflet was removed and replaced with a 23 mm. The impaired segment of ascending aorta was replaced with a Dacron graft afterwards. Conclusions In summary, we presented a surgical case of explantation of four TAVR Bioprostheses, which is so far the maximum number of surgical-explant devices ever reported. This extreme individual case aggregates our technical experiences with this unique category of patients and raise the concern of the best initial valve strategy for relatively younger patients with severe aortic valve stenosis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
