A widely used aortic valve bioprosthesis is susceptible to regurgitation between the sewing ring and the frame of the valve due to its relatively thin fabric coverage. In some cases this leak has been shown to resolve...
An 80-year-old woman with a history of surgical aortic valve replacement with a 21 mm St.Jude Medical Biocor porcine aortic valve 14 years prior presented with New York Heart Association(NYHA)class III symptoms,severe...

China is one of the countries which have a high incidence of heart valvular disease,but the use of biological valve is limited in China before because the majority of patients are young patients suffering from rheumat...
Objectives Transcatheter valve-in-valve (VIV) implantation for failed bioprostheses has become an alternative to open surgery in those deemed high risk. The purpose of this study was to evaluate the effectiveness an...
Background: Compared to the Western countries, Chinese patients present a special primary disease spectrum, diverse valvular pathogenesis, and different postoperational anticoagulation strategy. This research aimed t...

We sought to evaluate the feasibility and hemodynamic performance of a new self-expanding bioprosthesis and 16-F delivery system in sheep. A 23-mm new self-expanding aortic bioprosthesis was implanted in sheep (n = 1...
Background Percutaneous aortic valve replacement is a promising strategy in the treatment of patients with aortic valve stenosis. And many kinds of valved stents have been implanted in selected patients worldwide. How...
Background Bioprosthetic heart valves derived from glutaraldehyde (Glut)-fixed xenografts have been widely used to replace diseased cardiac valves. However, calcification and degeneration are common following their ...
