Starr-Edwards Mechanical Prosthesis for More Than 53 Years in the Mitral Position: A Case Report

International Journal of the Cardiovascular Academy
Valvular heart disease affects approximately 2.5% of the global population. Starr-Edwards (SE) prosthetic valves are commonly used in the aortic and mitral positions, with reported durability extending up to 40 years.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Patient Prosthesis Mismatch After SAVR and TAVR

Frontiers in Cardiovascular Medicine, 2022
Patient-prosthesis mismatch (PPM) remains one out of many factors to be considered during decision-making for the treatment of aortic valve pathologies. The idea of adequate sizing of a prosthetic heart valve was established by Rahimtoola already in 1978.
