ON THE VALVES OF THE HEART, AND THE SINUSES OF VALSALVAdoi:10.1016/S0140-6736(02)98800-8BryanE.L.Elsevier Ltd.Lancet
This overview of heart valve prostheses is based on a current review of clinical reports and focuses on the major complications that characterize long-term valve performance: thromboembolism, thrombosis, anti-coagulant-related bleeding, and structural failure. Author...
Bioprosthetic valves (see the image below) used in heart valve replacement generally offer functional properties (eg, hemodynamics, resistance to thrombosis) that are more similar to those of native valves. Implantation of prosthetic cardiac valves to tr
The two valves that regulate the flow of blood from the ventricles to the coronary, pulmonary, and systemic circulation are the semilunar valves (pulmonary and aortic). For more information about the heart, take a look below: Heart in situ Explore study unit The atrioventricular valves are...
In patients with malfunctioning prosthetic heart valves, symptoms are dependent on the type of valve, its location, and the nature of the complication. With valvular breakage or dehiscence, failure often occurs acutely with rapid hemodynamic deterioration. Failure occurs more gradually with valve thrombo...
More recently, Computational Fluid Dynamics (CFD) has emerged as a promising tool, which, alongside experimentation, can yield insights of unprecedented detail into the hemodynamics of prosthetic heart valves. For CFD to realize its full potential, however, it must rely on numerical techniques that ...
