Heart Valve Regurgitation: Causes, Symptoms and Treatment
Heart valve regurgitation means a valve does not close tightly. Blood leaks backward instead of moving forward. This forces the heart to work harder.
Over time, this strain can weaken the heart muscle.
What Is Heart Valve Regurgitation?
Your heart has four valves. They control blood flow in one direction.
When a valve leaks, some blood flows backward. This is called regurgitation.
The most common types are:
- Mitral valve regurgitation
- Aortic valve regurgitation
Both can range from mild to severe.
Mitral Valve Regurgitation
The mitral valve sits between the left atrium and left ventricle.
When it leaks, blood moves backward into the atrium. This raises pressure in the lungs.
Symptoms may include:
- Shortness of breath
- Fatigue
- Swelling in legs
- Rapid heartbeat
Long term leakage may lead to atrial fibrillation and other arrhythmias such as AFib or SVT.
Aortic Valve Regurgitation
The aortic valve controls blood leaving the heart.
When it leaks, blood flows back into the left ventricle. The ventricle enlarges over time. This is called myocardial remodeling.
Severe leakage can lead to heart failure symptoms.
Causes
Valve regurgitation can develop from many causes.
Common causes include:
- Bicuspid aortic valve also called BAV
- Other structural heart defects
- Congenital valve disease
- Rheumatic disease
- Infection
- High blood pressure
Rare conditions like Shone syndrome, pulmonary stenosis, or subaortic stenosis can also affect valve function.
Scar tissue from past heart injury may worsen valve performance.
How It Affects the Heart
When blood leaks backward, the heart pumps extra volume.
This leads to chamber enlargement and diastolic dysfunction.
Over time, pressure builds inside the heart and lungs.
Some people develop abnormal heart rhythms. These include atrial fibrillation.
In severe cases, the risk of sudden cardiac death rises.
Symptoms to Watch
Mild cases may cause no symptoms.
Moderate to severe leakage may cause:
- Shortness of breath
- Chest discomfort
- Fatigue
- Swelling
- Resting heart rate changes
Symptoms often worsen with stress or physical effort. Stress and emotional heart health also affect heart rhythm and blood pressure.
Diagnosis
Doctors begin with a physical exam. They may hear a heart murmur.
Tests include:
- Electrocardiogram also called ECG or EKG
- Ultrasound imaging of the heart
- Advanced cardiac imaging such as MRI
- Cardiac catheterization if surgery is considered
Imaging shows valve damage and chamber size.
Treatment Options
Treatment depends on severity.
Mild cases may only need monitoring.
Medicines can reduce symptoms and protect heart function.
These may include:
- Blood pressure medicines
- Diuretics
- Rhythm control drugs
If leakage is severe, surgery may be required. Valve repair is often preferred over replacement when possible.
Early treatment prevents long term damage.
Living With a Leaky Valve
Many people live normal lives with proper care.
Regular checkups are important. Monitor symptoms and heart rhythm.
Healthy habits protect the heart. Control blood pressure. Stay active within safe limits. Avoid smoking.
Final Thoughts
Heart valve regurgitation increases strain on the heart.
Early diagnosis and proper treatment protect heart function.
Regular follow up and healthy habits reduce long term risk.
