Heart valve disease is a condition that happens when one or more of the valves in the heart stop working properly. The human heart has four valves: the aortic valve, mitral valve, pulmonary valve, and tricuspid valve.
These valves act like small doors that open and close with every heartbeat. Their job is to make sure blood flows through the heart in the correct direction.
When the heart beats, the valves open to let blood move forward and then close tightly to stop blood from flowing backward.
This system helps the heart pump blood efficiently to the lungs and the rest of the body. If a valve becomes damaged, stiff, or leaky, the blood may not move the way it should. Over time, this can place extra strain on the heart and lead to serious health problems.
Heart valve disease can develop for several reasons. Some people are born with valve problems. Others develop them later in life due to aging, infections, high blood pressure, or other heart conditions. As people get older, heart valves can become thicker or less flexible, which can make it harder for them to open or close normally.
Because the heart is responsible for pumping oxygen-rich blood throughout the body, problems with the valves can affect many parts of the body.
The symptoms of heart valve disease can vary depending on which valve is affected and how severe the problem is. In some cases, symptoms develop slowly over many years. In other situations, they may appear suddenly.
One of the most common signs of heart valve disease is shortness of breath. Some people notice this when they are walking, climbing stairs, or doing other activities that require effort. Others may feel short of breath when lying flat in bed.
This can happen because a faulty valve may cause blood to flow backward and build up in the lungs. When fluid collects in the lungs, breathing becomes more difficult.
Another common symptom is fatigue. When the heart cannot pump blood effectively, the body may not receive enough oxygen. This can make people feel unusually tired, even during activities that once felt easy. Many people with valve problems say they feel exhausted after simple tasks like walking short distances or doing household chores.
Swelling in the body can also occur. Some people notice swelling in their ankles, feet, or legs. Others may develop swelling in the abdomen. This happens because poor heart function can cause fluid to build up in the body. In some cases, people may also gain weight quickly because their body is holding onto extra fluid.
Heart palpitations are another possible sign. Palpitations are sensations that feel like the heart is racing, pounding, fluttering, or skipping beats. When a valve does not work properly, the heart may try to compensate by beating harder or faster. This can make people more aware of their heartbeat.
Chest discomfort or pain can sometimes occur, especially when the aortic valve is affected. This type of pain may appear during physical activity when the heart has to work harder to pump blood through a narrowed valve. Although chest pain can have many causes, it should always be taken seriously and checked by a doctor.
Some people with heart valve disease may also feel dizzy or lightheaded. In severe cases, a person may faint. These symptoms can occur if the brain is not receiving enough blood and oxygen because the heart cannot pump effectively.
One of the earliest signs of a valve problem may be a heart murmur. A heart murmur is an unusual sound that a doctor can hear through a stethoscope while listening to the heart. Instead of the normal “lub-dub” sound of a heartbeat, a murmur may sound like a swishing or whooshing noise. This sound is caused by blood moving abnormally through a damaged valve.
Many people with heart valve disease do not notice symptoms right away. The condition can develop slowly, and early signs may be mild. Sometimes people assume that symptoms such as tiredness or shortness of breath are simply part of aging. Because of this, valve problems may go unnoticed for a long time.
Doctors can diagnose heart valve disease through several steps. First, they will ask about symptoms and medical history. They may listen to the heart with a stethoscope to check for murmurs.
One of the most important tests used to examine heart valves is an echocardiogram. This test uses sound waves to create moving pictures of the heart, allowing doctors to see how the valves open and close and how blood flows through them.
If heart valve disease is detected early, treatment can often help manage the condition. Some people may only need regular monitoring and medications to control symptoms. In more serious cases, doctors may recommend procedures or surgery to repair or replace the damaged valve.
With modern medical treatments, many people with heart valve disease can continue to live active and healthy lives. Recognizing the warning signs and seeking medical advice early can make a big difference in protecting heart health.
