What is considered a mechanical heart valve?
Mechanical valves Mechanical heart valves are made from materials such as titanium and carbon. They usually consist of two leaflets and a metal ring surrounded by a ring of knitted fabric, which is sewn onto the heart in place of the original valve.
How long can you live with a mechanical valve?
Mechanical valves don’t usually wear out. They usually last 20 years or more. Other problems might happen with the valve, such as an infection. As long as you have the valve, you and your doctor will need to watch for signs of problems.
What is the function of mechanical heart valves?
Their primary function is to prevent retrograde blood flow into the atria during ventricular systole. The aortic and pulmonic valves are collectively known as the semilunar valves, and their primary function is to prevent retrograde blood flow into the ventricles during diastole.
Can you live a normal life with a mechanical heart valve?
Mechanical valves can last a lifetime, but they come with increased risks of blood clotting and bleeding, as well as the need to take the blood-thinning medication warfarin.
What happens when a mechanical heart valve fails?
Signs and symptoms of mechanical valve thrombosis may include muffled mechanical heart sounds, a new murmur, dyspnea, heart failure and cardiogenic shock. Thrombosis of right-sided valves causes right-sided heart failure, characterized by swelling of the legs, abdomen or both, without pulmonary congestion.
Does heart valve surgery shorten your life?
Patients who have undergone surgical replacement of the heart’s aortic valve have a shorter life expectancy than the normal population, the loss in life expectancy being particularly marked in the young.
What is the life expectancy of a mechanical heart valve?
Mechanical valves don’t usually wear out. They usually last 20 years or more. Other problems might happen with the valve, such as an infection. As long as you have the valve, you and your doctor will need to watch for signs of problems. After surgery, you may need to take the blood thinner called warfarin. This will lower your risk of blood clots.
Are mechanical heart valves better than biological ones?
Mechanical heart valve often the safest choice. The benefits of a mechanical valve compared with a biological valve persist until the age of 70 for mitral-valve replacement, according to a new Stanford study. Nov 8 2017. Joseph Woo and his colleagues found in a study that mechanical heart valves may be a safer option than valves made of animal
What are the types of mechanical heart valves?

What are mechanical heart valves made of?
Transcatheter aortic valve replacement devices are combined with a valve mechanical (made of stainless steel or nitinol) and valve leaflets Biological (made of cow heart tissue or bovine). These aortic valves are available in various sizes (29mm
