Double Valve ReplacementDouble Valve Replacement. A double valve replacement is a replacement of both the mitral and the aortic valve, or the entire left side of the heart. This type of surgery is not as common as the others and the mortality rate is slightly higher.


Reasons for Replacement

The valves of the heart are responsible for allowing nutrient-rich blood to flow through the chambers of your heart. Each valve is supposed to close completely after ushering in blood flow. Diseased heart valves aren’t always able to perform the job as well as they should.

Stenosis, or a narrowing of the blood vessels, causes a less-than-normal amount of blood to flow to the heart. This causes the muscle to work harder. Leaky valves can also pose a problem. Instead of closing tightly, a valve may remain slightly open, letting blood flow backwards. This is called regurgitation. The signs of valvular heart disease can include:




shortness of breath


chest pain

fluid retention, especially in the lower limbs

Heart valve repair is also a solution for valvular heart disease. In some people, the damage is too far advanced and a total replacement of the affected valve is the only option.


Types of Replacement Valves

Mechanical and biologic valves are used to replace faulty valves. Mechanical valves are artificial components that have the same purpose as a natural heart valve. They’re created from carbon and polyester materials that the human body tolerates well. They can last between 10 and 20 years. However, one of the risks associated with mechanical valves is blood clots. If you receive a mechanical heart valve, you’ll need to take blood thinners for the rest of your life to reduce your risk of stroke.

Biologic valves, also called bioprosthetic valves, are created from human or animal tissue. There are three types of biologic heart valves:

An Allograft or homograft is made of tissue taken from a human donor’s heart.

A porcine valve is made from pig tissue. This valve can be implanted with or without a frame called a stent.

A bovine valve is made from cow tissue. It connects to your heart with silicone rubber.

Biologic valves don’t increase your risk of developing blood clots. This means you most likely won’t need to commit to a lifetime of anti-clotting medication. A bioprosthetic doesn’t last as long as a mechanical valve and may require replacement at a future date.


Your doctor will recommend which type of heart valve you get based on:

your age

your overall health

your ability to take anticoagulant medications

the extent of the disease


Types of Valve Replacement Surgery

Aortic Valve Replacement

The aortic valve is on the left side of the heart and serves as an outflow valve. Its job is to allow blood to leave the left ventricle, which is the heart’s main pumping chamber. Its job is also to close so that blood doesn’t leak back into the left ventricle. You may need surgery on your aortic valve if you have a congenital defect or disease that causes stenosis or regurgitation.

The most common type of congenital abnormality is a bicuspid valve. Normally, the aortic valve has three sections of tissue, known as leaflets. This is called a tricuspid valve. A defective valve has only two leaflets, so it’s called a bicuspid valve. A recent study found that aortic valve replacement surgery has a 94 percent five-year survival rate. Survival rates depend on:

your age

your overall health

other medical conditions you have

your heart function


Mitral Valve Replacement

The mitral valve is located on the left side of the heart. It serves as an inflow valve. Its job is to allow blood from the left atrium to flow into the left ventricle. Surgery may be required if the valve doesn’t fully open or completely close. When the valve is too narrow, it can make it difficult for blood to enter. This can cause it to back up, causing pressure in the lungs. When the valve doesn’t close properly, blood can leak back into the lungs. This can be due to a congenital defect, infection, or a degenerative disease.

The defective valve will be replaced with either a metal artificial valve or a biological valve. The metal valve will last a lifetime but requires you to take blood thinners. The biological valve lasts between 15 to 20 years, and you won’t be required to take medication that thins your blood. The five-year survival rate is about 91 percentTrusted Source. The following also play a role in survival rate:

your age

your overall health

other medical conditions you have

your heart function

Ask your doctor to help assess your personal risks.


Double Valve Replacement

A double valve replacement is a replacement of both the mitral and the aortic valve, or the entire left side of the heart. This type of surgery is not as common as the others and the mortality rate is slightly higher.


Pulmonary Valve Replacement

The pulmonary valve separates the pulmonary artery, which carries blood to the lungs for oxidation, and the right ventricle, which is one of the heart’s chambers. Its job is to allow blood to flow from the heart to the lungs through the pulmonary artery. The need for pulmonary valve replacement is usually due to stenosis, which restricts blood flow. Stenosis may be caused by a congenital defect, infection, or carcinoid syndrome.


What is the success rate of heart valve replacement surgery?

When a person’s aortic stenosis becomes severe, the average survival rate without surgical intervention is only 50 percent after two years and only 20 percent after five years. Evidence is also clear that with proper treatment, most people enjoy a return to good health and add many years to their life.


How dangerous is heart valve replacement surgery?

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.


Can you die from a leaky heart valve?

If left untreated, a leaky valve could lead to heart failure. … You may need heart surgery to repair or replace the valve for severe leakage or regurgitation. Left untreated, severe mitral valve regurgitation can cause heart failure or heart rhythm problems (arrhythmias).

Some physical signs of heart valve disease can include:

Chest pain or palpitations (rapid rhythms or skips)

Shortness of breath, difficulty catching your breath, fatigue, weakness, or inability to maintain regular activity level.

Lightheadedness or loss of consciousness.

Swollen ankles, feet or abdomen.


Can heart valve problems be treated with medication?

Your doctor may also recommend making healthy lifestyle changes and taking medications to treat symptoms. You may eventually need heart valve surgery to repair or replace the diseased heart valve. … Doctors continue to study catheter procedures to repair or replace heart valves.


Do you feel better after heart valve replacement?

You will feel tired and sore for the first few weeks after surgery. You may have some brief, sharp pains on either side of your chest. … The incision in your chest may be sore or swollen. These symptoms usually get better after 4 to 6 weeks.
