Which is better tissue valve or mechanical valve?

Mechanical valves last longer than tissue valves. They are less likely to wear out or break down. If you are age 50 or younger, a mechanical valve may be a good choice. That’s because you are young enough that you probably will live longer than a tissue valve might last.

How long will a bovine aortic valve last?

While new technologies are being designed and tested, cow valve replacements typically last between 10-20 years. The main advantage of mechanical valves is that they are very durable and expected to last the life of the patient.

Why are mechanical valves better than biological valves?

Mechanical valves may last a lifetime, but they come with an increased risk of blood clots, necessitating the long-term use of blood thinners. Biologic valves made from pig or cow tissue typically don’t cause clotting, but they wear out sooner, often requiring patients to undergo another surgery.

Which heart valve is the easiest to repair?

Pulmonary valve This valve connects the right ventricle to the pulmonary artery. It’s responsible for allowing blood to flow toward the lungs. “The pulmonary valve is less likely to need repair than other valves,” Dr. Burns says.

What are the disadvantages of using a cow tissue heart valve?

Disadvantages of cow tissue valve:

• made from cow so possible objections on religious grounds.
• new procedure so could be unknown risks.
• risks of using a stent, eg blood clots, stent breaking or valve tearing.
• not proven as a long term treatment.
• may be rejected.

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 long will a mechanical heart valve last?

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.

Is it better to repair or replace a heart valve?

In general, heart valve repair is usually the first choice because it is associated with a lower risk of infection, preserves valve strength and function, and reduces the need to take blood-thinning medications for the rest of your life, which may be necessary with certain types of valve replacement.

Which heart valve is most commonly repaired?

Two valves—the aortic and mitral valves—are the most common ones that need repair or replacement surgery. Defects are less common in the two other valves, but they can also develop problems that require surgery.

How many years does a mechanical valve last?

Are bovine valves better than porcine valves for aortic valve replacement?

Ten of 15 papers assessed the complication profile due to aortic valve replacement in both valve types. Four papers concluded that bovine valves are superior, whereas only one favoured porcine valves. Five papers showed a similar complication profile between both valves.

What type of heart valve replacement works best for You?

Aortic valve repair has excellent long-term results in appropriate patients with leaking valves. There are two main types of heart replacement valves to choose from — mechanical and biological. Which one will work best for you? It depends on your situation, Dr. Svensson says. The choice of valve type is influenced by: Your age.

Should I get a mechanical heart valve or biologic heart valve?

Currently, the American College of Cardiology and the American Heart Association recommend mechanical valves for people under age 50 and biologic (tissue) valves for those over 70. For people like you who fall between those ages, neither type has an absolutely clear advantage over the other.

Why is it so hard to choose a heart valve?

Because of design limitations of each valve type, it’s a complex choice influenced by a patient’s anticipated lifespan and lifestyle. Mechanical valves may last a lifetime, but they come with an increased risk of blood clots, necessitating the long-term use of blood thinners.
