Lewes, DE — 12/28/2017 — The first generation of device designs for mechanical heart valves included a caged-ball construct. These devices functioned similar in fashion to a ballpoint pen, serving as a one-way flow point for blood between the chambers of the heart. However, this design was not ideal in that the heart had to work harder to maintain flow through the valve. Subsequent generations of device design focused on an open-and-close valve, which allowed for central blood flow. Mechanical heart valves may be combined with a conduit for use in cases requiring the reconstruction of both the aortic heart valve and the aorta.
Mechanical heart valves are prosthetic devices designed to replicate the function of the natural valves of the human heart. Mechanical valves are designed to outlast the patient and some have been stress-tested to last several hundred years. Although mechanical valves are long-lasting and generally only require one surgery for installation, they contribute to an increased risk of blood clot formation. As a result, mechanical valve recipients often take anti-coagulant (blood thinning) drugs such as warfarin for the rest of their lives, which makes the patient more prone to bleeding. Given their durability, mechanical valves are primarily indicated for younger patients and for mitral valve replacement due to its high-pressure gradient.
The primary advantage of mechanical over tissue valves is that once a mechanical valve is implanted, they never wear down and rarely need to be replaced. Mechanical valves are made from either pyrolytic carbon or titanium that has been coated with pyrolytic carbon. Pyrolytic carbon is similar to graphite and is used for many biomedical applications. They also can have parts made from Teflon, polyester or polyethylene terephthalate.
