We all know that our heart is an amazing organ. It works like a little motor all the time. So, inside this heart, there are special parts like gates that help take blood from one side and send it to the other side. Today, we are going to talk about one such important gate, or valve. It is called the Tricuspid Valve.
What is this tricuspid valve? Simply put...
Imagine that your heart has four chambers. Two upper chambers and two lower chambers. This tricuspid valve is located between the upper chamber on the right side of the heart (which we call the right atrium) and the lower chamber on the right side (which is the right ventricle) . It is like a door. It is also called the right atrioventricular valve. But in everyday speech, we often use the word tricuspid valve.
This valve helps blood flow in exactly one direction by opening and closing here and there. Its main job is to stop blood from flowing back in the wrong direction.
What happens to the tricuspid valve? What is its function?
Our heart is like a little pump. It pumps blood throughout our bodies. This blood travels in a specific path through the four chambers of the heart. Every time your heart beats, the two upper chambers (atria) collect oxygen-poor blood from the body. Then the two lower chambers (mitral valves) contract, which means they tighten a little, and pump the blood out of the heart.
As the blood pumps, the valves in the heart open and close. This allows blood to flow from one place to another. Most importantly, these valves ensure that the blood flows at the right time and in the right direction.
If we talk about the Tricuspid Valve, it is what makes sure that blood flows from the right atrium to the right ventricle. It also stops blood from flowing back between those two chambers. Imagine, when the right atrium fills with blood, the Tricuspid Valve opens, allowing some blood to go into the right ventricle. Then the right ventricle contracts and sends the blood to the lungs. At that time, the Tricuspid Valve closes very tightly, so that the blood does not go back into the right atrium. Do you understand?
Where is the tricuspid valve located?
As we said before, this is on the right side of the heart. To be precise, it's located between the right ventricle (lower chamber) and the right atrium (upper chamber). It's located vertically, meaning from top to bottom.
What is the tricuspid valve made of?
The tricuspid valve is made up of three thin, but very strong flaps of tissue. These are called leaflets or cusps. These flaps have three names, depending on how they are positioned: anterior, posterior, and septal. These flaps are attached to papillary muscles in the atrium by thin, strong cords called chordae tendineae.
Every time the heart beats, these valves open and close. The sound of the heart that you hear is the sound of those valves opening and closing. Isn't it amazing?
What are the diseases that can affect the right atrial-mitral valve?
Imagine what happens if this tricuspid valve doesn't work properly. Then the blood may not flow in the right direction. Or it may leak back in the wrong direction. When that happens, your heart has to work harder to pump blood to the rest of your body.
There are three main types of problems that can be seen with the tricuspid valve:
1. Tricuspid atresia: This is a congenital heart defect. A person with this condition has only thick tissue where the valve should be. This restricts blood flow and may cause the right ventricle to not develop properly. This usually requires surgery.
2. Tricuspid regurgitation: This is when blood leaks backward through the tricuspid valve, much like a door that doesn't close properly and leaks water.
3. Tricuspid stenosis: In this condition, the opening of the tricuspid valve is very narrow. This restricts the flow of blood between the two chambers. It's like a blocked pipe that makes it difficult for water to flow.
What are the causes of Tricuspid Valve problems?
There are several possible reasons why this valve may be having problems. Let's take a look at what they are:
- Radiation therapy to the chest as a treatment for a cardiac tumor or cancer.
- A congenital defect is a structural defect that is present at birth. For example, a valve having only two leaflets, or having more than three.
- Diseases that affect the connective tissue in your body, for example, Marfan syndrome.
- Recreational drug use.
- Enlarged right ventricle.
- Infections that cause swelling of the heart muscle, for example endocarditis (an infection of the heart) or rheumatic fever.
- Using a weight loss drug called "fen-phen" (fenfluramine and phentermine). (This is now banned).
What are the symptoms of tricuspid valve problems?
As we mentioned earlier, when the tricuspid valve is not working properly, your heart has to work harder to pump blood. This can make you feel tired and weak .
If the problem with this valve becomes severe over time, other symptoms may appear. These include:
- Cold skin.
- Enlarged liver.
- An abnormal heart sound (heart murmur). This sound is heard when a doctor listens with a stethoscope.
- Feeling your heart beating faster or having a fluttering sensation in your chest (palpitations).
- Feeling like the veins in your neck are throbbing.
- Swelling of the stomach, legs, ankles, or feet.
If you have one or more of these symptoms, it is best to seek medical advice immediately.
What tests can be done to see if my heart valves are working properly?
If a doctor suspects that you have a problem with your tricuspid valve, they may refer you to a cardiologist, a specialist who diagnoses and treats heart disease.
There are several tests to check the tricuspid valve:
- Physical exam: In this, the doctor listens to your heart beat with a stethoscope.
- Chest imaging: A chest X-ray or cardiac MRI takes pictures of the inside of the chest.
- Echocardiogram: This is the main test to diagnose heart valve problems. Also called an echo. It produces moving images of the heart's chambers, valves, and how it pumps blood.
- Electrocardiogram (ECG): This test, also called an ECG or EKG, measures the electrical activity of the heart.
- Exercise stress test: In this test, a doctor measures your heart rate while you walk on a treadmill.
- Cardiac catheterization: This procedure can check for backflow and how far the tricuspid valve is open. In this procedure, a doctor inserts a long, thin tube called a catheter through a blood vessel into the heart.
What are the treatments for Tricuspid Valve related conditions?
Whether you need treatment or continued observation for your tricuspid valve problem depends on the severity of your valve problem and the symptoms you are experiencing.
If treatment is needed, your doctor may recommend the following:
- Diuretics: These are medications that reduce the amount of extra water in the body through urination. They help reduce swelling caused by tricuspid valve problems.
- Tricuspid valve repair: A surgeon can reshape, widen, or tighten the leaflets of the tricuspid valve. He or she can also implant an artificial ring to strengthen the valve.
- Tricuspid valve replacement: A surgeon can remove the tricuspid valve and replace it with an artificial mechanical valve or a biological valve taken from an animal.
- Transcatheter valve repair: If you have severe, symptomatic tricuspid regurgitation, an interventional cardiologist can repair the valve through the skin (that is, without a large incision) (percutaneous repair) .
- Transcatheter valve replacement: If you have severe and symptomatic tricuspid regurgitation, your interventional radiologist may suggest percutaneous valve replacement.
If I have tricuspid stenosis or tricuspid regurgitation, how can I keep my heart healthier?
If you have a problem with your tricuspid valve, these tips can help keep your heart healthier and prevent complications:
- Avoid smoking. This is very important.
- Control your blood pressure and cholesterol levels.
- Eat a heart-healthy diet low in saturated and trans fats, and rich in fruits and vegetables.
- Exercise regularly. Even a short walk is good.
- Keep regular appointments with your primary care provider so he or she can listen to your heart and identify any problems early.
- Take antibiotics (as directed by your doctor) before dental treatment or other medical procedures.
- Tell every healthcare provider who treats you, including your dentist, that you have a heart valve problem.
If I have a problem with my tricuspid valve, when should I see a doctor?
If you have a problem with your tricuspid valve, you should report any signs of infection right away. This can help you identify and treat conditions like endocarditis (a heart infection). Call your doctor right away if you have symptoms of infection, such as body aches, fever, or sore throat. Also, be sure to keep all your regular heart check-ups.
