What They Are, What Causes Them, and How They’re Treated
Your heart is a powerful pump, working non-stop to circulate blood throughout your body. At the center of that operation are your heart valves—small but mighty flaps that ensure blood flows in the right direction. When these valves don’t work properly, it can affect how efficiently your heart functions, leading to a variety of symptoms and health concerns.
Let’s break down everything you need to know about heart valve problems—from causes and symptoms to diagnosis and treatment.
🫀 What Are Heart Valves?
Your heart has four valves, each opening and closing once per heartbeat:
-
Aortic valve
-
Mitral valve
-
Tricuspid valve
-
Pulmonary valve
These valves make sure blood flows forward through the heart’s chambers and out to the body or lungs—not backward. When a valve becomes damaged or diseased, it can:
-
Not open fully (called stenosis)
-
Not close properly (called regurgitation or insufficiency)
In either case, the heart must work harder to keep blood flowing, which can lead to heart enlargement, fatigue, or even heart failure if untreated.
⚠️ Types of Heart Valve Problems
1. Valve Stenosis
-
The valve doesn’t open properly due to thickening or stiffening.
-
This restricts blood flow and puts extra pressure on the heart.
Common types:
-
Aortic stenosis (most common, especially in older adults)
-
Mitral stenosis
2. Valve Regurgitation (Leaky Valve)
-
The valve doesn’t close completely, so blood leaks backward.
-
This can cause fluid buildup and reduce oxygen delivery to the body.
Common types:
-
Mitral regurgitation
-
Aortic regurgitation
3. Valve Prolapse
-
One or more valve flaps bulge back into the chamber, often leading to regurgitation.
-
Most common in the mitral valve (mitral valve prolapse).
🧬 Causes of Heart Valve Problems
Valve issues can be congenital (present at birth) or acquired later in life. Some common causes include:
-
Aging (natural wear and tear)
-
Rheumatic fever (a complication of untreated strep throat)
-
Infections (such as endocarditis)
-
Calcium buildup on valves
-
Heart attack or heart failure
-
Connective tissue disorders (like Marfan syndrome)
-
Radiation therapy to the chest
🩺 Symptoms of Heart Valve Problems
Some people have no symptoms for years, but as the condition worsens, they may experience:
-
Chest pain or discomfort
-
Fatigue or weakness
-
Shortness of breath (especially with exertion or lying down)
-
Heart palpitations or irregular heartbeat
-
Swelling in the ankles, feet, or abdomen
-
Dizziness or fainting
-
A heart murmur (often the first clue, heard during a physical exam)
🧪 How Heart Valve Problems Are Diagnosed
Doctors use several tools to assess valve function:
-
Stethoscope exam: To detect murmurs or abnormal sounds
-
Echocardiogram (Echo): An ultrasound of the heart that shows valve structure and motion
-
Electrocardiogram (EKG/ECG): Records electrical activity
-
Chest X-ray: May show heart enlargement or fluid in the lungs
-
Cardiac MRI or CT scan: Provides detailed imaging of heart structures
-
Cardiac catheterization: Measures pressures inside the heart and checks for blockages
💊 Treatment Options for Valve Problems
Treatment depends on the type, severity, and your overall health.
🔹 Lifestyle and Monitoring
-
Mild cases may just need regular check-ups and healthy lifestyle changes.
🔹 Medications
While medications won’t fix the valve, they can help manage symptoms and complications:
-
Diuretics (to reduce fluid buildup)
-
Beta-blockers or ACE inhibitors (to control blood pressure)
-
Blood thinners (to prevent clots, especially in atrial fibrillation)
🔹 Surgical or Interventional Procedures
1. Valve Repair
-
Often preferred when possible (especially for the mitral valve)
-
Involves reshaping, tightening, or reinforcing the valve
2. Valve Replacement
-
Mechanical valves (long-lasting but require blood thinners)
-
Biological valves (made from pig or cow tissue, don’t last as long but often don’t need blood thinners)
3. Minimally Invasive Procedures
-
TAVR (Transcatheter Aortic Valve Replacement): A catheter-based alternative to open-heart surgery for aortic stenosis
-
Balloon valvuloplasty: Opens a narrowed valve, often used temporarily
🧘♂️ Living with a Heart Valve Condition
With proper management, many people with valve problems live full and active lives. Here’s how to support your heart health:
-
Eat a heart-healthy diet (low in sodium and saturated fat)
-
Exercise regularly, as recommended by your doctor
-
Manage blood pressure and cholesterol
-
Avoid tobacco and limit alcohol
-
Take prescribed medications as directed
-
Report new symptoms promptly
💬 Final Thoughts
Heart valve problems can range from mild to severe—but with today’s diagnostic tools, medications, and surgical options, they’re more manageable than ever. The key is early detection and consistent care.
If you’ve been told you have a murmur or experience symptoms like fatigue or breathlessness, don’t ignore them. A simple test like an echocardiogram can provide vital answers—and peace of mind.
