Symptoms of aortic regurgitation: the silent phase and warning signs
Medically reviewed by
Prof. Vlad Gariboldi
Updated on
August 6, 2026
You have aortic regurgitation and are starting to feel something during physical exertion. Or perhaps your cardiologist says you are asymptomatic, yet your usual activities feel more difficult than before. These situations are common with this condition: understanding how symptoms develop can help clarify things.
Key points
- Chronic aortic regurgitation is often asymptomatic for several years: the left ventricle gradually adapts to the overload without causing noticeable discomfort.
- The first symptoms appear during exertion: shortness of breath, unusual fatigue, and palpitations. Their occurrence at rest marks a more advanced stage of the condition.
- Some patients unconsciously reduce their activity level to avoid feeling short of breath, which can mask the actual progression of the condition.
- Sudden, intense shortness of breath, whether or not associated with chest pain, is a warning sign that warrants an urgent medical consultation.
Why the heart can remain silent for years
In chronic aortic regurgitation, the left ventricle (the heart chamber responsible for pumping blood to the body) gradually dilates to accommodate the volume of blood that leaks back with each beat. This adaptation allows the heart to maintain near-normal function for years without the person feeling anything at all.
This compensation mechanism raises a question many patients ask: "I don't have any symptoms, does that mean everything is fine?" The absence of symptoms does not mean the condition is not progressing. This is precisely why regular monitoring via echocardiography is central to managing this disease, regardless of the severity of the leak at the time of diagnosis.

The progression of symptoms: from exertion to rest
When the left ventricle's compensation mechanisms reach their limits, symptoms begin to appear. They usually follow a characteristic progression.
- Early phase: shortness of breath only during intense exertion, fatigue setting in faster than usual, and palpitations (the sensation of a stronger or faster heartbeat).
- Intermediate phase: shortness of breath during moderate exertion, sometimes chest pain during exertion, and significantly reduced tolerance for physical activity.
- Advanced stage: shortness of breath at rest, orthopnea (difficulty breathing while lying down, requiring sleep in a semi-upright position), lower limb edema, extreme fatigue.

Situations requiring special attention
The nature and progression rate of symptoms vary depending on the cause of aortic regurgitation. Certain profiles require tailored cardiological monitoring.
- Bicuspid aortic valve: the valve may remain asymptomatic for a long time, but progression to significant regurgitation often occurs before age 65. When a bicuspid valve is identified, cardiological guidelines recommend screening for first-degree relatives.
- Genetic connective tissue disorders (Marfan syndrome, Ehlers-Danlos): monitoring is generally intensified because the ascending aorta may be affected alongside the valve.
- High blood pressure: recognized as a factor that worsens the progression of aortic regurgitation, it is included in the overall assessment of the case.
- Autoimmune or inflammatory diseases (lupus, ankylosing spondylitis): valvular involvement may be part of a broader clinical picture; tailored cardiological monitoring is standard in these contexts.
Frequently Asked Questions
What are the first symptoms of aortic regurgitation?
The first symptoms appear during physical exertion: shortness of breath that occurs more quickly than usual, abnormal fatigue, and sometimes palpitations. In chronic cases, several years may pass between the initial diagnosis and the onset of these first signs.
Can you have aortic regurgitation without any symptoms?
Yes, the majority of chronic aortic regurgitation cases are discovered in patients who feel no discomfort. The heart compensates for the overload for years through the progressive dilation of the left ventricle.
Is shortness of breath during exercise always a sign that aortic regurgitation is worsening?
Not necessarily: shortness of breath during exercise can have several causes unrelated to aortic regurgitation. A medical evaluation can determine whether this symptom is linked to the progression of the condition or another cause.
At what stage of aortic regurgitation do symptoms appear?
Characteristic symptoms (shortness of breath, fatigue, palpitations) generally appear when the left ventricle begins to dilate significantly. Their occurrence at rest indicates a more advanced stage, which requires prompt evaluation.
Aortic regurgitation and fatigue: are they linked?
Fatigue is one of the common symptoms of aortic regurgitation as cardiac output decreases. It is not specific to this condition and must be evaluated within the overall clinical context.

Did you know?
Some patients gradually and unconsciously reduce their physical activity to avoid feeling short of breath. They perceive themselves as asymptomatic, when in reality they have simply adapted to a reduced exercise capacity. This phenomenon, described in standard cardiology literature, highlights the value of an exercise stress test to evaluate actual tolerance for physical activity.
Sudden, intense shortness of breath accompanied by acute chest pain may indicate acute aortic regurgitation. This is a medical emergency distinct from chronic forms and requires immediate care.
