Aortic Regurgitation
Aortic Regurgitation (AR) occurs when the aortic valve fails to close completely during diastole (the heart's relaxation phase), allowing blood to leak backward from the aorta into the left ventricle.
This backward flow increases the volume of blood the left ventricle must handle with each heartbeat. Over time, the heart enlarges and works harder to maintain adequate blood flow to the body.
Why is it Important?
Over time, severe aortic regurgitation can cause:
- Enlargement of the left ventricle
- Reduced heart function
- Heart failure
- Shortness of breath
- Reduced exercise capacity
Key Message
Aortic Regurgitation can develop gradually and remain silent for years. Early diagnosis and timely treatment can prevent long-term damage to the heart.
Why is it Dangerous?
If severe and left untreated, aortic regurgitation can lead to:
- Left ventricular enlargement
- Reduced heart pumping function
- Heart failure
- Cardiac arrhythmias
- Reduced exercise capacity
Who is at Risk?
- People with bicuspid aortic valve
- Individuals with aortic root disease or aneurysm
- People with rheumatic heart disease
- Patients with infective endocarditis
- Individuals with connective tissue disorders such as Marfan Syndrome
Common Symptoms
Many people have no symptoms initially.
As the condition progresses, symptoms may include:
- Shortness of breath
- Fatigue
- Palpitations
- Chest discomfort
- Reduced exercise tolerance
Can it be Treated?
YES
Treatment may include:
- Regular monitoring
- Blood pressure control
- Aortic valve repair
- Aortic valve replacement
- Surgery for associated aortic root aneurysms Surgical repair of the enlarged aorta
India records approximately 29 lakh (2.9 million) cardiovascular disease (CVD) deaths per year, including heart attacks, strokes, heart failure, and other heart and blood vessel diseases.
