Structural and Valvular Heart Disease
What is Structural Heart Disease?
Structural heart disease refers to a category of heart conditions that primarily involve the structure of the heart, rather than its blood vessels or electrical system. It encompasses a wide range of conditions, both congenital (present at birth) and acquired (developed over time). These conditions can affect various components of the heart, including the heart valves, chambers, walls, and muscle. Common types of structural heart disease include:
- Cardiomyopathy
This condition disrupts the heart muscle's ability to pump blood effectively, leading to symptoms like fatigue, shortness of breath, and swelling. - Congenital Heart Defects
Abnormalities that occur during fetal development can result in congenital heart defects, which vary in complexity and impact blood flow. - Coronary Artery Disease (CAD)
CAD arises from the buildup of plaques in the coronary arteries, restricting blood flow to the heart muscle and potentially leading to chest pain or heart attacks. - Heart Failure
In heart failure, the heart cannot pump enough blood to meet the body's demands, resulting in symptoms like fluid retention, fatigue, and shortness of breath. - Pericardial Disease
This condition involves inflammation of the pericardium, the sac-like structure around the heart, and can cause chest pain and other discomfort.
What is Valvular Heart Disease?
Valvular heart disease, also known as valvular disease or valvular heart disorder, refers to a group of conditions that affect the heart's valves. The heart has four essential valves: the aortic valve, the mitral valve, the tricuspid valve, and the pulmonary valve. These valves play a crucial role in ensuring that blood flows in one direction through the heart chambers, allowing for effective circulation throughout the body.
Valvular heart disease occurs when one or more of these valves do not function properly. There are several types of valvular heart disease, including:
- Valvular Stenosis
This occurs when a heart valve becomes narrowed or constricted, making it difficult for blood to flow through the valve. Valvular stenosis often leads to increased pressure in the heart chamber before the affected valve. - Valvular Regurgitation (Insufficiency)
In this condition, a valve does not close tightly, allowing blood to flow backward (regurgitate) into the previous chamber. This can cause the heart to work harder to pump blood efficiently. - Mitral Valve Prolapse
Mitral valve prolapse is a condition in which the flaps (leaflets) of the mitral valve bulge backward into the left atrium when the heart contracts. This can result in regurgitation of blood.
Structural and Valvular Heart Disease Symptoms
The symptoms of structural and valvular heart disease can vary depending on the specific condition, the severity of the disease, and individual factors. It's important to note that some individuals with structural or valvular heart disease may remain asymptomatic, particularly in the early stages of the disease. In such cases, the condition may be discovered incidentally during a routine medical examination or diagnostic test.
If you or someone you know experiences any of these symptoms or has risk factors for heart disease, it is essential to seek medical evaluation promptly. Early diagnosis and appropriate management can significantly improve outcomes and quality of life for individuals with these conditions. Some common symptoms associated with these types of heart disease include:
Common Symptoms of Structural Heart Disease
- Fatigue
People with structural heart disease often experience fatigue or a general lack of energy, which can interfere with daily activities. - Shortness of Breath
Difficulty breathing or shortness of breath, especially during physical exertion, is a common symptom. Severe cases may lead to shortness of breath even at rest. - Swelling
Fluid retention can result in swelling (edema), typically in the legs, ankles, feet, or abdomen. - Chest Pain or Discomfort
Chest pain or discomfort may occur, particularly in individuals with conditions like cardiomyopathy or coronary artery disease. - Palpitations
Irregular or rapid heartbeats (palpitations) can be a symptom of structural heart disease, especially when it affects the heart's electrical system. - Fainting or Syncope
Some people may experience fainting episodes or syncope due to reduced blood flow or abnormal heart rhythms caused by structural heart disease. - Coughing or Wheezing
Fluid buildup in the lungs can lead to a persistent cough or wheezing.
Common Symptoms of Valvular Heart Disease
- Heart Murmur
A heart murmur is often an early sign of valvular heart disease and can be detected by a healthcare provider during a physical examination. - Shortness of Breath
Similar to structural heart disease, valvular heart disease can cause shortness of breath, especially during physical activity. - Chest Pain or Discomfort
Chest pain or discomfort may occur, particularly when the disease affects the aortic valve. - Palpitations
Irregular heartbeats or palpitations can result from valvular regurgitation or stenosis. - Fatigue
Fatigue is a common symptom of valvular heart disease, especially as the disease progresses. - Swelling
Fluid retention and swelling in the legs, ankles, feet, or abdomen can occur when valvular heart disease leads to heart failure.
Structural and Valvular Heart Disease Treatments
The optimal treatment plan is tailored to the specific structural or valvular defect, the severity of impairment, risk factors, and the preferences of the informed patient. A combination of lifestyle changes, medications, and procedures helps provide the best outcomes. Common approaches include:
- Medications
Medications are often used to manage symptoms, control underlying conditions, and reduce the risk of complications associated with structural and valvular heart disease. Common medications include diuretics (to reduce fluid retention), beta-blockers (to slow the heart rate and reduce blood pressure), ACE inhibitors or ARBs (to lower blood pressure), and anticoagulants (to prevent blood clots). Antibiotics may be prescribed before dental or surgical procedures for individuals with certain types of valvular heart disease to prevent infective endocarditis. - Lifestyle Modifications
Lifestyle changes play a significant role in managing heart disease. These changes may include adopting a heart-healthy diet low in salt and saturated fats, maintaining a healthy weight, quitting smoking, and engaging in regular physical activity. - Minimally-Invasive Procedures
Some structural and valvular heart conditions can be treated with minimally invasive procedures, such as transcatheter valve repair or replacement. These procedures are performed using a catheter inserted through a blood vessel, often in the groin. Transcatheter aortic valve replacement (TAVR) is an example of a minimally invasive procedure used to replace a diseased aortic valve. - Surgical Interventions
In some cases, open-heart surgery may be necessary to repair or replace damaged heart valves or address other structural issues. - Cardiac Rehabilitation
Cardiac rehabilitation programs provide structured exercise, education, and support to individuals recovering from heart surgery or managing heart disease. These programs can help improve physical fitness and overall heart health. - Regular Monitoring
Individuals with structural or valvular heart disease often require regular follow-up appointments with their healthcare providers to monitor their condition, adjust medications, and assess any changes in symptoms or heart function.
