You asked: How do prosthetic heart valves work?

How long can a person live with an artificial 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.

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.

How often do prosthetic heart valves need to be replaced?

Mechanical valves usually last 20 years or more. You are less likely to need a mechanical valve replaced in your lifetime.

Can you live a long life after heart valve surgery?

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.

You’ll likely begin to feel better almost right away. Your condition will improve gradually, and you’ll notice that each day you’ll feel a little bit better. However, you’ll have to make some lifestyle adjustments to get the most out of your new or repaired heart valve.

How do I know if my artificial heart valve is failing?

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.

What can go wrong with a mechanical heart valve?

What are the risks of mechanical valves? 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 is the average age for heart valve replacement?

The current American Heart Association and American College of Cardiology (AHA/ACC) guidelines recommend that biologic valves are reasonable in patients aged 70 or above (Class IIa recommendation), whereas a mechanical valve is reasonable for patients below 60 years of age (Class IIa recommendation) 1.

Which heart valve is hardest to replace?

Aortic valve stenosis is a defect that narrows or obstructs the aortic valve opening, making it difficult for the heart to pump blood into the body’s main artery (aorta). Typically the aortic valve has three tightly fitting, triangular-shaped flaps of tissue called cusps (tricuspid aortic valve).
