What are the advantages of a mechanical heart valve?
The main advantage of mechanical valves is that they’re hard-wearing and less likely to need replacing. This means they’re often better for younger people having a valve replacement.
What are the disadvantages of artificial heart valves?
There is a higher rate of thrombotic and thromboembolic complications with mechanical heart valves. The main disadvantage with mechanical prosthetic heart valves is that patients will have to take anti coagulants [blood thinners] for the rest of their lives to prevent the formation of dangerous blood clots.
Is mechanical or biological heart valve better?
Biological heart valves are used in the majority of replacements and are generally considered, across all age groups, to be the best option. Mechanical valves are much more durable, but they are also more likely to succumb to clotting problems. These clotting issues can lead to serious consequences.
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 can go wrong with a mechanical heart valve?
The main risk of a mechanical valve is that you can get blood clots that could cause a heart attack or stroke. To prevent blood clots, you will take a blood thinner called warfarin (such as Coumadin) every day.
What are the disadvantages of mechanical valves?
Mechanical heart valves also have disadvantages. The blood flow around a mechanical heart valve is at higher stress then a bioprosthetic valve that can lead to blood clotting abnormality and potentially development of clot on the valve.
How many years does a mechanical valve last?
That said, a mechanical mitral valve can is reported to last between 20 to 25 years. Some suggest that the life of a mechanical mitral valve may even be longer. You have to remember two things. First, heart valve replacement surgery is a relatively new medical procedure.
How long can you live with 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.
Does heart valve replacement 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.
How long can you live with a mechanical heart valve?
What are the disadvantages of mechanical heart valve?
Mechanical heart valves also have disadvantages. The blood flow around a mechanical heart valve is at higher stress then a bioprosthetic valve that can lead to blood clotting abnormality and potentially development of clot on the valve.
What are the advantages of mechanical valves?
As discussed above, the most prominent advantage of the mechanical valves is their durability, in a fully grown patient they have been known to last over 40 years. Tissue valves may need to be replaced one or more times in a patient’s life.
Do mechanical heart valve replacements save lives?
Mechanical heart valve replacements can save the lives of those they are implanted in, however like any man made technology they are far from perfect. All three types show a high degree of durability, but some have better performance characteristics than others.
What is a mechanical heart valve?
Hamza Atcha, Wendy F. Liu, in Principles of Heart Valve Engineering, 2019 Mechanical heart valves were conceived over 50 years ago and are composed entirely of synthetic materials to form mechanical devices that replicate the function of natural heart valves.
