Breakthrough research helps improve artificial heart valve design.CANONSBURG, Pa.--(BW HealthWire)--April 24, 1997--A British research team from the Medical Physics Department of the University of Sheffield The University of Sheffield is a research university, located in Sheffield in South Yorkshire, England. Reputation Sheffield was the Sunday Times University of the Year in 2001 and has consistently appeared as their top 20 institutions. and the Royal Hallamshire Hospital The Royal Hallamshire Hospital is a general & teaching hospital located in Sheffield, England. It is in the city's West End, facing Glossop Road, close to the University of Sheffield's main campus. used ANSYS ANSYS Analysis System Inc.'s (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :ANSS) ANSYS design analysis and optimization software to develop an artificial heart valve artificial heart valve Cardiovascular surgery A synthetic-mechanical or natural–porcine–valve surgically placed into the heart to replace a defective or malfunctioning valve; the aortic and mitral valves are the most frequently replaced with AHVs that functions as closely to the natural heart as possible. By analyzing different valve alternatives as an integral part of the design process, heart valve manufacturers will be able to reduce their product development time. In addition, the research team's work in verifying, optimizing, and improving heart valve implants can lead manufacturers to new designs that more closely follow the natural operation of the human heart. The Sheffield team is "working to bridge the divide between theoretical means of measuring the operation of artificial implants and actual performance in the living patient," explained a key researcher, Dr. Rodney Hose, lecturer in medical physics and clinical engineering in the university's Medical Physics Department. "In the longer term, the prospects are even more exciting. It should eventually be possible to use analysis software to model complex moving and elastic/viscoelastic tissue, and therefore to produce an accurate analysis of the prosthetic valve in its final operating environment." In addition, the team hopes that its work using ANSYS/FLOTRAN(TM) will help designers and manufacturers improve valve designs that avoid blood flow problems so patients will not need the lifelong anticoagulation drug therapy which is costly and can cause side effects.

The Sheffield team's milestones will impact manufacturers in the medical industry, providing valuable information that will lead to better designed products. Combined, these efforts result in improved quality of life for cardiac patients."
