Abstract:
Background: Aortic valve replacement (AVR) in intermediate-risk (IR) patients is particularly challenging when determining the type of prosthesis to use. Rapid-deployment valves (RD-V) are emerging as a potential alternative in this patient population. Objectives: To compare early mortality, postoperative complications, and transvalvular hemodynamic parameters between AVR with conventional valves and RD-V in IR patients. Methods: We conducted a retrospective observational study of consecutive IR patients (STS-Prom score 4-8) undergoing AVR with conventional prostheses and RD-V between 2007 and

Full text
Abstract:
When partially closed, steam turbine governing valves rely on flow separation from the valve head and seat to generate loss and throttle the flow. The aim of this type of valve is to avoid separation and therefore eliminate loss when the valve is fully open, and to have stable and controllable separations at all other valve lifts. Any significant unsteadiness in the valve flow can result in unacceptable mechanical vibration of the valve, which in extreme cases can lead to failure. Results will be discussed from work that has been undertaken into valve flow instabilities at Leicester University

Abstract:
One of the major achievements in cardiac surgery over the past 30 years has been the ability to replace severely diseased heart valves with prosthetic ones. The option of using prosthetic heart valves for the treatment of valvular diseases has improved and prolonged many lives. This is reflected in around 120,000 heart valve replacement operations carried out every year in North America alone to correct the cardiovascular problems of stenosis, insufficiency, regurgitation, etc. The development of artificial heart valves depends on reliable knowledge of the hemodynamic performance and physiolo

Abstract:
Polypyrrole is a conducting polymer that can change in volume as its oxidation state is altered. This change in volume, operable at low voltages, can be used to create small actuating devices. The goal of this thesis is to evaluate the use of polypyrrole for the creation of a low voltage polymer valve and to demonstrate the mechanisms that could be used to create these valves. There are a number of challenges in using polypyrrole in a commercially viable valve; it must be able to withstand large temperature variations, have a high strain (to minimize mechanical amplification), have high

Abstract:
The development of electrohydraulic floating-disc valves at the University of Surrey started in the early 1980's. The progress in the last ten years since then has shown that floating-disc valves have the advantages of fast response time, reliable operation, simple configurations, few critical dimensions with no precision sliding surfaces, leading to low cost design and manufacture. They have great potential to fill the gap between conventional solenoid valves and high precision servo valves. However, limitations existed in previous designs hindering further development; for instance relativel

Material selection is an important step during the design process of an object. The goal is to produce an object to meet the requirement with minimum cost. During the recent years with discovery of oil and gas in deep water, oil and gas industry facing new challenges of handling corrosive material in seabed that gives more importance and criticality to material selection of equipment for this kind of application. Hydrogen sulfide (H2S), chloride and carbon dioxide (CO2) have made the big challenges for material that handle corrosive fluids in the seabed.This report presents a brief review of m
