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.
