        • Transcatheter aortic valve replacement for pure severe native aortic valve regurgitation with high surgical risk: a case report

          Pure native aortic valve regurgitation (NAVR) is one of the common heart valve diseases, and the prognosis of symptomatic chronic NAVR is poor. Although transcatheter aortic valve replacement (TAVR) is currently an "off-label" procedure, it remains the option for patients with high risk for surgery. In this case, an 81-year-old man with multiple comorbidity and high Society of Thoracic Surgeons score, the risk for surgery is rather high. Through the preoperative evaluation by the multidisciplinary heart team, considering that the patient had calcification at the junction of annulus, as well as mild aortic stenosis, after careful consideration, 29# Venus A-Valve was chosen. After the procedure, the symptoms were obviously improved and the follow-up effect was good. Due to various causes of NAVR, great anatomical variation of annulus, little calcification of aortic valve, and lack of anchor point and other problems, the procedure to treat NAVR with TAVR is still difficult. At the same time, there are few valve systems developed for the anatomical characteristics of aortic regurgitation valve. TAVR in the treatment of patients with high risk for surgery still requires long-term practice and technical development.
