Mechanistic Insights into Bioprosthetic Heart Valve Calcification and Anti-Calcification Strategies

Reviews in Cardiovascular Medicine
Prosthetic heart valves are crucial for treating valvular heart disease and serve as substitutes for native valves. Bioprosthetic heart valves (BHVs) are currently the most common type used in clinical practice.

Age-Specific Outcomes of Bioprosthetic vs. Mechanical Aortic Valve Replacement: Balancing Reoperation Risk with Anticoagulation Burden

Journal of Cardiovascular Development and Disease
Background: The choice of prosthesis for aortic valve replacement (AVR) remains challenging. The risk of anticoagulation complications vs. the risk of aortic valve reintervention should be weighed.

Computer-assisted Methods for Design Optimization of Cardiac Bioprosthetic Valves [PDF]

, 1984
Excessive mechanical stresses on valvular leaflets are considered an important factor in the degeneration of cardiac porcine bioprosthetic valves. This study describes a computer-assisted numerical model of a bioprosthetic valve which estimates the ...

An In Vivo Experimental Study of Bioprosthetic Cardiac Valves in the Tricuspid Position

, 1983
viii, 46 p.Because bioprosthetic cardiac valves undergo degeneration and calcification, an in vivo investigational model was developed to study these problems. The animal model utilized In this study was the domestic sheep (Ovis aries).
