Heart Valve Disease

Your heart has four valves that act like one-way doors, making sure blood flows in the right direction. If one or more of these valves isn't working correctly, it's called heart valve disease. This means the valve might not open or close completely. When this happens, blood flow through your heart and to the rest of your body can be affected.

The treatment for heart valve disease depends on which valve is affected and how serious the problem is. In some cases, surgery is needed to fix or replace the faulty valve. This surgery aims to restore normal blood flow.

Heart valve problems can sometimes go unnoticed for a long time. However, when signs do appear, they can include a variety of symptoms. These might be:

• Shortness of breath: This can happen even when you're resting, or when you're doing something active, or even when you're lying down. It's like your body isn't getting enough air.
• Feeling tired (fatigue): You might just feel unusually drained and lack energy.
• Chest pain: This pain could be sharp or dull.
• Dizziness: This can make you feel lightheaded or unsteady.
• Swelling in your ankles and feet (edema): This is often caused by fluid buildup.
• Fainting: Losing consciousness briefly.
• Irregular heartbeat: Your heart might beat too fast, too slow, or skip beats. This can feel like fluttering or a thumping sensation.

If you're experiencing any of these symptoms and suspect you might have a heart valve problem, it's important to see a doctor. They can perform tests to determine the cause. You might be referred to a cardiologist, who is a doctor specializing in heart conditions. Early diagnosis and treatment are key to managing heart valve disease effectively.

If you're experiencing symptoms that might be related to heart valve problems, schedule a doctor's appointment. A doctor specializing in heart conditions, called a cardiologist, may be consulted.

The human heart has four chambers: two atria (upper chambers) and two ventricles (lower chambers). The atria receive blood returning to the heart, and the ventricles pump blood out to the body. Valves in the heart ensure blood flows in the correct direction.

Problems with these heart valves can cause heart valve disease. One type of problem is stenosis, where a valve opening narrows, like a doorway getting too small. This makes it harder for blood to pass through. Another problem is regurgitation, where the valve doesn't close completely, allowing blood to leak backward. Valve prolapse happens when the valve flaps bulge out of shape. This can, but doesn't always, lead to regurgitation. In some cases, a valve doesn't form properly at all, called atresia. This typically involves a solid piece of tissue blocking the opening.

The heart has four main valves: the aortic valve, mitral valve, pulmonary valve, and tricuspid valve. Each valve has flaps (called leaflets or cusps). These flaps open and close with each heartbeat to control blood flow. If a valve doesn't work correctly, it can lead to problems with blood circulation throughout the body.

Here's a closer look at different types of heart valve disease:

• Stenosis: The valve flaps thicken and stiffen, sometimes fusing together, making the valve opening narrower. This reduces the amount of blood that can flow through.
• Regurgitation: The valve flaps don't close completely, allowing blood to flow backward. This is like a leaky faucet in the heart.
• Prolapse: The valve flaps are stretched out and floppy, bulging backward. This can cause blood to leak back (regurgitation).
• Atresia: The valve doesn't form correctly and is blocked by a solid piece of tissue. This mostly affects the pulmonary valve.

Some people are born with heart valve problems (congenital heart valve disease). Adults can develop heart valve disease due to factors like infections, natural aging processes, or other heart conditions.

Heart valve disease can happen for a number of reasons. One common factor is getting older. As we age, our risk of developing problems with our heart valves increases.

Certain infections, like rheumatic fever or infections that spread through the bloodstream, can also damage the heart valves. These infections can cause inflammation and scarring that can disrupt the valve's ability to open and close properly.

Having had a heart attack or other types of heart problems can also increase the risk of heart valve disease. The stress and damage from these events can weaken the valves.

Conditions like high blood pressure, high cholesterol, and diabetes are also linked to heart valve problems. These conditions, often referred to as heart disease risk factors, can put extra strain on the heart and gradually harm the valves over time. For example, high blood pressure can put more pressure on the valves, making them less effective at controlling blood flow. Similarly, high cholesterol can contribute to the buildup of plaque, which can further damage the valves. Diabetes can also increase the risk of inflammation, which can contribute to valve problems.

Problems with your heart valves can lead to serious health issues. These problems can make your heart work harder and less efficiently, potentially causing:

• Heart failure: This happens when your heart can't pump enough blood to meet your body's needs. It can feel like you're constantly tired, have trouble breathing, and may swell in your ankles or feet.

• Stroke: A stroke occurs when blood flow to a part of your brain is blocked or interrupted. This can lead to lasting physical or cognitive problems.

• Blood clots: Blood clots can form in your heart or blood vessels and travel to other parts of your body. If they get stuck, they can block blood flow, potentially causing damage to organs or tissues.

• Heart rhythm problems (arrhythmias): Your heart might beat too fast, too slow, or irregularly. This can cause dizziness, lightheadedness, chest pain, or even fainting.

• In severe cases, heart valve disease can be life-threatening. It's important to get prompt medical attention if you suspect you might have heart valve problems.

Diagnosing Heart Valve Disease

Doctors use several methods to diagnose heart valve disease. First, they'll ask about your symptoms and medical history, and conduct a physical exam. Sometimes a "whooshing" sound, called a heart murmur, can be heard using a stethoscope. This indicates a possible problem with the heart valves.

To get a clearer picture of your heart's health, various tests might be performed:

• Echocardiogram: This test uses sound waves to create images of your heart. It shows how blood flows through your heart and how well your heart valves are working. Different types of echocardiograms exist, chosen based on the reason for the test and your health.

• Electrocardiogram (ECG or EKG): This quick test records the electrical signals in your heart. Sensors (electrodes) are placed on your chest and sometimes your legs, connected to a computer that displays the results. This shows how your heart is beating.

• Chest X-ray: This shows your heart and lungs. It can reveal if your heart is larger than normal or if there's fluid around your lungs. Fluid buildup can be a sign of some heart valve problems.

• Cardiac MRI: This test uses magnetic fields and radio waves to create detailed images of your heart. It can help determine how severe the heart valve disease is.

• Exercise (Stress) Tests: These tests often involve walking on a treadmill or riding a stationary bike while your heart is monitored. They show how your heart responds to physical activity. If exercise isn't possible, medicines can sometimes mimic the effects of exercise on the heart.

• Cardiac Catheterization: This test isn't frequently used to diagnose heart valve disease, but it may be done if other tests aren't conclusive or to determine the severity of the problem. A thin tube (catheter) is inserted into a blood vessel (often in the groin or wrist), guided to the heart, and dye is injected. The dye helps the arteries show up better on X-rays and videos.

Stages of Heart Valve Disease:

After a diagnosis, your doctor may classify your heart valve disease into stages. This helps determine the best course of treatment. The stages depend on various factors, including:

• Symptoms: Are you experiencing any symptoms?
• Severity: How severe is the valve disease?
• Valve Structure: What is the condition of the valve(s)?
• Blood Flow: How is blood flowing through your heart and lungs?

The stages are generally categorized as:

• Stage A (At Risk): You have risk factors for heart valve disease, but no symptoms.
• Stage B (Progressive): You have mild or moderate valve disease, but no symptoms.
• Stage C (Asymptomatic Severe): You have severe valve disease, but you're not experiencing any symptoms.
• Stage D (Symptomatic Severe): You have severe valve disease and are experiencing symptoms.

Treating Heart Valve Problems

Heart valve problems can be treated in various ways, depending on several factors:

• Symptoms: How noticeable the problems are.
• Severity: How bad the valve damage is.
• Progression: Whether the problem is getting worse.

Treatment options often include:

Lifestyle Changes: A healthy diet and exercise can help manage symptoms and overall heart health. This may involve adjusting your diet to reduce sodium and unhealthy fats, and increasing physical activity.

Regular Checkups: Regular visits to your doctor are crucial to monitor the condition and catch any changes early.

Medications: Some people with heart valve problems need medication to manage symptoms. This might include blood thinners to prevent blood clots, or other medications to help the heart function better.

Surgery: If the condition is severe or worsening, surgery may be necessary to repair or replace the damaged valve. This might be done even if symptoms aren't immediately present. Surgery might be performed during another heart procedure.

Valve Repair:

If possible, surgeons will often try to repair a damaged valve rather than replace it. This involves:

• Patching holes: Fixing any tears or openings in the valve.
• Separating fused flaps: Opening up flaps that have stuck together.
• Repairing support cords: Fixing or replacing any damaged tissues that support the valve flaps.
• Removing excess tissue: Taking away any extra tissue that is preventing the valve from closing properly.
• Reducing valve size: Making the valve smaller to allow the flaps to close tightly.

Specific repair procedures include:

• Annuloplasty: This strengthens the ring around the valve to improve its function.
• Valvuloplasty: This procedure repairs the valve flaps themselves. One common example is fixing mitral valve prolapse. This often involves inserting a small tube with a balloon into a blood vessel and using the balloon to widen the valve opening.

Valve Replacement:

If a valve can't be repaired, it may need to be replaced. There are two main types of replacement valves:

• Mechanical Valves: These are artificial valves made of strong materials. They last a long time, but patients need to take blood thinners for life to prevent blood clots.
• Biological Valves: These valves are made from animal (cow, pig) or human tissue. They are less durable than mechanical valves and may need to be replaced later. Sometimes, a patient's own pulmonary valve can be used to replace a damaged aortic valve, which is called the Ross procedure.

Different Types of Valve Replacement Procedures:

• Open-Heart Surgery: This is the traditional method, requiring a larger incision.
• Minimally Invasive Surgery: This approach uses smaller incisions and often results in a quicker recovery.
• Transcatheter Aortic Valve Replacement (TAVR): This procedure is used for aortic valve problems. A catheter is inserted into a blood vessel and guided to the heart. A new valve is placed through the catheter. This method often has less impact on the body than open-heart surgery.

The specific type of surgery chosen depends on several factors, including the patient's age, overall health, and the nature of the valve problem.

Living with heart valve disease can be challenging, but there are ways to manage it and feel better. One important thing is to get support. Talking to friends, family, or joining a support group can help a lot. Sharing your feelings with others who understand what you're going through can ease stress and make you feel less alone.

Another key part of managing heart valve disease is stress management. Finding healthy ways to cope with stress is crucial. Regular exercise, mindfulness techniques (like meditation or deep breathing), and connecting with supportive people can all help. If you're struggling with anxiety or depression, talk to your doctor or other healthcare provider. They can suggest strategies to help you manage these feelings. They can also work with you to create a plan that addresses these issues alongside your heart valve disease.
