A 49-year-old female suffered from dyspnea on exertion and jaundice from June, 2009. She had undergone aortic valve replacement with Carpentier-Edwards pericardial bioprosthesis due to active infectious endocarditis 23-years previously. The echocardiography showed severe aortic stenosis with moderate regurgitation. She was diagnosed as having prosthetic valve malfunction. Re-replacement of the aortic valve with mechanical valve was successfully performed. As far as we can see, this is one of the longest-term cases of implantation of pericardial bioprosthesis.

The Ross procedure continues to be the best procedure to address unrepairable aortic valve pathology, especially in young adults. The Achilles heel of this procedure has been aortic root dilation and the potential need for a reoperation that may be associated with slightly increased risks in addition to the need for intervention on the pulmonary outflow tract. Modifying the Ross procedure by autograft inclusion inside a Dacron graft seems to have the potential advantage of stabilizing the autograft diameter, which may be associated with improved durability and decrease the need for future intervention.

Background: The long-term comparative results between porcine and pericardial bioprostheses for surgical aortic valve replacement (SAVR) is debated. Scarce information exists concerning direct comparative evaluation among contemporary devices. We compared late and very late results in a single center series (N=3,983 cases).

Valvular heart disease (VHD) poses a significant threat to human health, and the transcatheter heart valve replacement (THVR) is the best treatment for severe VHD. Currently, the glutaraldehyde cross-linked commercial bioprosthetic heart valves (BHVs) remain the first choice for THVR. However, the cross-linking by glutaraldehyde exhibits several drawbacks, including calcification, inflammatory reactions, and difficult endothelialization, which limits the longevity and applicability of BHVs.

Background: The self-expanding, supra-annular Evolut valve is an established platform for Transcatheter Aortic Valve Implantation (TAVI). Evolut PRO introduced an outer sealing wrap to mitigate paravalvular leakage. We evaluated the 3-year clinical outcomes and valve performance of the Evolut PRO in standard clinical practice for severe aortic stenosis (AS) patients at intermediate or higher risk for surgery.

Polymer heart valves are a promising alternative to bioprostheses, the use of which is limited by the risks of calcific deterioration of devitalized preserved animal tissues. This is especially relevant in connection with the increasingly widespread use of transcatheter valves. Advances in modern organic chemistry provide a wide range of polymers that can replace biological material in the production of valve prostheses.
