Frequent question: What are the advantages and disadvantages of artificial heart valves?

Advantages of tissue valves compared to mechanical valves include the avoidance of lifelong warfarin therapy to prevent the development of blood clots. A disadvantage is their relatively poor durability compared to mechanical valves, with many requiring a re-operation in 10 to 20 years.

What are the advantages of artificial heart valves?

Advantages: The mechanical prosthetic heart valves are very durable and guarantee 20-30 years of functioning in ideal conditions. The coating with pyrolytic carbon in mechanical valves also decreases the chance of blood clotting on the valve surface.

What are the advantages of replacement valves?

Replacing a Diseased Valve

Mechanical Valves Tissue or Biological Valves
Benefits • Long-term durability • Only have to take blood-thinning medications for the first few months after surgery.

What is an disadvantage of a mechanical replacement heart valve?

The biggest drawback of mechanical heart valve replacement is the need for lifelong blood thinning medication (anticoagulation). Blood-thinning treatment comes with risk of bleeding complications. The most appealing part of a bioprosthetic heart valve is that it does typically require blood-thinning medication.

What are the disadvantages of biological heart valves?

The disadvantages of biological heart valves are a smaller valve orifice area (3) and the risk of structural valve degeneration (4), which may necessitate reoperation (table 1).

What are the disadvantages of an artificial heart?

In addition, the artificial heart carries its own set of risks, including blood clots, bleeding, infections and device malfunctions. Gurudevan recommends additional research to examine the use of the total artificial heart as a permanent solution for patients, rather than simply a bridge to transplant.

What are the risks of artificial heart valves?

Serious complications of prosthetic valves occur at a rate of about 2% to 3% per patient-year. Complications include thromboembolism, prosthesis-patient mismatch, structural valve dysfunction, endocarditis, and hemolysis.

What are the effects of valve replacement?

Possible risks of heart valve repair or replacement surgery include:

  • Bleeding during or after the surgery.
  • Blood clots that can cause heart attack, stroke, or lung problems.
  • Infection.
  • Pneumonia.
  • Pancreatitis.
  • Breathing problems.
  • Arrhythmias (abnormal heart rhythms)
  • The repaired or replaced valve doesn’t work correctly.

How long do you live after heart valve replacement?

Long-Term Survival

For patients approximately 40 years old at the time of surgery, the life expectancy was reduced by 20 years compared to that of general population. This data suggests that a 42-year-old patient undergoing aortic valve replacement (AVR) with a tissue valve is expected to live to 58 years of age.

What is the life expectancy of someone with an artificial heart valve?

For example, they estimated that a 45-year-old undergoing mechanical valve replacement has a life expectancy of 19 years (compared with 34 years in the general population), and lifetime risk of thrombo-embolism, bleeding, and re-intervention of 18, 15, and 10%, respectively.

How safe is heart valve replacement?

Valve repair or replacement is generally safe. However, as with any surgery or procedure, complications can occur. Possible risks associated with treatment include: Bleeding during or after treatment or damage to the blood vessels.

Can you drink alcohol after heart valve replacement?

Water – avoid sugary soft drinks and drink alcohol only in moderation.

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.

What are the advantages and disadvantages of using biological and mechanical valves?

The main advantage of biological valves is that there’s less risk of clots forming, so lifelong anticoagulant treatment isn’t usually necessary. But biological valves tend to wear out a bit faster than mechanical valves and may eventually need to be replaced after many years.

What is artificial valve replacement?

An artificial heart valve is a one-way valve implanted into a person’s heart to replace a valve that is not functioning properly (valvular heart disease). Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.

What is the difference between biological and artificial valve replacements?

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.
