Heart Valve Diseases: Types, Symptoms, Causes, and Treatment Options

Any abnormality or failure affecting any one of the four valves in the heart (aortic, mitral, tricuspid, and pulmonary) is referred to as a heart valve disease. These conditions can pose severe health risks, such as heart failure, if they are not treated.

Maintaining the unidirectional flow of blood through your heart’s chambers and out to your body mainly depends on your heart valves. Imagine them as traffic lights that make sure blood flows freely and in an ordered manner, avoiding backflow or congestion.

This article will thoroughly explore the types, causes, symptoms, and treatment options for heart valve diseases, which will help us maintain cardiovascular health.

Heart Valve Diseases

Heart valve diseases are a collection of disorders that affect the valves of the heart, compromising their ability to control the flow of blood appropriately. These valves, which include the tricuspid, aortic, mitral, and pulmonary valves, are essential for regulating blood flow through each chamber of the heart and the rest of the body.

Many health issues and complications can occur when these valves malfunction as a result of damage, deformity, or disease. Understanding heart valve diseases is essential for early detection, prompt treatment, and effective management to prevent further complications and maintain heart health.

Types of Heart Valve Diseases

These are the heart valve diseases that can impact a person’s general health and cardiovascular health:

Aortic Valve Disease

The aortic valve, found between the left ventricle and the aorta, regulates blood flow throughout the body from the heart. A narrowing of this valve, called aortic stenosis, can limit blood flow and make your heart work harder, which can result in symptoms like breathlessness and chest pain. However, when the valve malfunctions and blood flows backwards into the heart, it is known as aortic regurgitation.

Mitral Valve Disease

The mitral valve regulates the left atrium and left ventricle’s blood flow. Mitral valve prolapse is a frequently occurring condition in which there is a murmur or clicking sound when the valve flaps close too slowly. 

Fatigue is a symptom of mitral stenosis, which involves the narrowing of the valve, while irregular heartbeats are a symptom of mitral regurgitation, which involves the leaking of the valve.

Tricuspid Valve Disease

The tricuspid valve, which is located between the heart’s right atrium and right ventricle, is essential for regulating how well blood flows through the chambers of the heart. Despite being less common than other valve disorders, tricuspid valve diseases can nevertheless have a significant impact on heart health. 

When the tricuspid valve narrows, it causes tricuspid stenosis, which limits blood flow from the right atrium to the right ventricle. Due to fluid accumulation from inefficient blood flow, this constriction may cause symptoms like exhaustion, swelling in the legs and abdomen, and discomfort in the stomach.

Pulmonary Valve Disease

The pulmonary valve, found between the right ventricle and the pulmonary artery, regulates the blood flow from the heart to the lungs. A variety of conditions can impact the function of the pulmonary valve. 

The narrowing of the pulmonary valve interrupts the flow of blood from the right ventricle to the lungs and is known as pulmonary stenosis. This limitation may result in symptoms like fatigue, breathing problems, and chest pain, particularly when engaging in physical activity.

Symptoms of Heart Valve Diseases

Common symptoms of heart valve diseases include:

  • Breathlessness, particularly when moving around or when lying down.
  • Weakness and fatigue, even after little effort.
  • Fluid retention which results in swelling in the legs, ankles, or abdomen.
  • An erratic or fast heartbeat referred to as heart palpitations.
  • Chest pain or discomfort, which could get worse when you exert yourself.

Causes of Heart Valve Diseases

Heart valve diseases can arise from a variety of causes, which include:

Congenital Heart Defects

Structural abnormalities that occur at birth are known as congenital heart defects. These defects can lead to heart valve diseases by causing abnormalities in the formation or function of the valves. Examples include malformed or abnormally structured valves that do not open or close properly, leading to leakage (regurgitation) or narrowing (stenosis) of the valves.

These congenital abnormalities might not show symptoms until adulthood, such as bicuspid aortic valves or mitral valve prolapse. Early detection and adequate management are essential for addressing congenital heart defects and preventing complications as individuals age.

Age-Related Changes

The heart valves can stiffen and lose their flexibility with age. Aortic stenosis is one condition that can result from calcium accumulation in which the valve narrows and restricts blood flow. Age-related changes in heart valve function can be lessened with routine monitoring and lifestyle changes like eating a healthy diet and exercising regularly.

Rheumatic Fever

The mitral valve, in particular, can be harmed by a history of rheumatic fever, which is frequently the result of untreated strep throat. Regurgitation (leaking) or stenosis (narrowing and scarring) may result from this damage. Rheumatic fever and its related complications can be avoided with prompt treatment of strep throat infections and routine follow-up care.


Bacterial endocarditis, which affects the heart valves, can be highly damaging and result in valve dysfunction. People who already have heart problems or compromised immune systems are more vulnerable to this condition. To minimise the risk of infective endocarditis, practising good oral hygiene and treating infections as soon as possible is recommended.

Other Medical Conditions

Heart valve diseases are possible from conditions such as hypertension, hypercholesterolemia, and autoimmune disorders, which may worsen the heart or lead to valve inflammation and damage. Preventing heart valve diseases and lowering the risk of complications requires managing these underlying medical conditions with medication, lifestyle modifications, and regular monitoring.

Treatment Options for Heart Valve Diseases

The goals of treatment for heart valve disorders are to reduce symptoms, enhance cardiac performance, and prevent complications. Here are the treatment options available for heart valve diseases:


Medication is essential for the management of heart valve diseases because it lowers the chance of complications and relieves symptoms. Numerous drugs are often given to treat various facets of the illness and enhance general cardiac health. 

Diuretics, for example, are widely used to lessen the accumulation of fluid in the body, mainly when heart valve disorders cause swelling and fluid retention. Diuretics relieve symptoms like swelling in the legs and ankles and breathing difficulties by encouraging the excretion of extra fluid through urine. Also, beta-blockers are often used to control blood pressure and heart rate, which reduces the pressure on the heart and increases its effectiveness.

Surgical Treatments

Surgical treatments are required when medications are not adequate to address problems with the heart valves. These operations aim to address the underlying issues and bring the valves back to optimal performance. 

Valves can be repaired surgically, maintaining the original valve by addressing specific problems like calcified deposits or structural reshaping. When it comes to valves, this approach tries to preserve their natural integrity. The valve may need to be replaced, though, in more severe situations where repair is not practical. The dysfunctional valve is replaced with a mechanical or biological valve during valve replacement surgery.

Minimally Invasive Procedures

Heart valve disease treatment has changed significantly as a result of technological advancements, which provide less invasive alternatives to conventional surgical procedures. Transcatheter aortic valve replacement (TAVR), which has become an innovation in the treatment of aortic valve stenosis, is one such innovative procedure.

As an alternative to traditional open-heart surgery, transcatheter aortic valve replacement (TAVR) uses catheters directed by imaging techniques like fluoroscopy and echocardiography to access the heart through small incisions in the groin or chest. By using these catheters, a collapsible artificial valve can be deployed at the location of the diseased aortic valve, effectively replacing the damaged valve without requiring open heart surgery.


In conclusion, It is essential to understand heart valve diseases, their causes, symptoms, and available treatments if one wants to keep their heart healthy. You can effectively prevent or manage these conditions and take charge of your health by being proactive and well-informed. You must seek medical advice and investigate your treatment options if you suspect you might have symptoms of heart valve disease.
