The aorta is the primary artery responsible for carrying blood away from the heart and circulating it throughout the body. The aortic valve facilitates this process by regulating blood flow as it exits the heart and enters the aorta. However, in cases of aortic stenosis, the aortic valve fails to open fully, resulting in reduced blood flow from the heart. In this condition, decreased blood flow can potentially lead to a range of symptoms and complications associated with the situation. Doctors can locate the valve in the left ventricle of the aorta.
- Stenosis: A narrowing or constriction of the aortic valve opening.
- Symptoms: Chest pain, shortness of breath, and fatigue.
- Causes: Thickening and stiffening of the valve leaflets.
- Complications: Heart failure, arrhythmias, and sudden cardiac death.
- Diagnosis: Echocardiogram, electrocardiogram, and cardiac catheterization.
- Treatment: Medication, valve replacement, or repair.
- Prognosis: The prognosis depends on the severity of the stenosis and the timing.
Aortic valve stenosis is a medical condition where the opening of the aortic valve becomes narrowed, leading to obstruction of blood flow from the heart to the rest of the body. Cardiologists can locate the aortic valve between the left ventricle and the aorta of the heart, the largest artery in the body.

- Aortic valve stenosis is a condition where the aortic valve becomes narrowed.
- Cardiologists can locate the aortic valve between the left ventricle and the aorta.
- Aortic valve stenosis develops during the thickening and stiffening of the valve leaflets, which reduces the amount of blood that can pass through the valve with each heartbeat.
- Symptoms may include chest pain, shortness of breath, and fatigue.
- If left untreated, it can lead to heart failure.
- Treatment options may include medication or surgery, such as valve replacement or repair.
- The appropriate treatment will depend on the severity of the stenosis and the individual patient's medical history and condition.
What are the symptoms of aortic stenosis?
- Aortic stenosis can cause many symptoms, although some people may not experience any symptoms.
- Shortness of breath is a common symptom of aortic stenosis, particularly during physical activity or lying down.
- Chest pain or discomfort, often described as tightness or pressure, may occur as the heart has to work harder to pump blood through the narrowed valve.
- Fatigue and weakness may occur as the heart becomes less efficient at pumping blood to the rest of the body.
- Dizziness or fainting may occur in a decreased blood flow to the brain.
- Heart palpitations or irregular heartbeats may occur as the heart compensates for the increased workload caused by aortic stenosis.
- Aortic stenosis may cause swelling in the ankles, feet, or abdomen due to fluid buildup.
- Symptoms of aortic stenosis can worsen over time and may eventually lead to heart failure or sudden cardiac arrest.
What are the causes of Aortic stenosis?
- Aortic stenosis causes the aortic valve to narrow, leading to increased work for the left ventricle to pump blood exit through the valve.
- The extra work leads to the thickening of the ventricle walls, which can cause chest pain.
- As the pressure continues to rise, blood can back up into the lungs, which limits the amount of blood that reaches the brain and other parts of the body.
- Aortic stenosis can be congenital and usually develops later in life, especially in older people with calcium buildup on the valve (calcific aortic stenosis).
- Children with aortic stenosis may have other conditions present from birth.
- People born with abnormal aortic or bicuspid valves will certainly experience calcium buildup sooner.
- Chest radiation can also lead to faster development of calcium buildup in rare cases.
- After having strep throat or scarlet fever, a person may develop rheumatic fever. However, valve problems related to rheumatic fever typically do not manifest until 5 to 10 years or more after the initial occurrence of rheumatic fever.
The progression rate of aortic stenosis can vary among individuals. While some may experience a slow progression over several years, others may experience a faster progression. It is important to seek timely treatment, as waiting too long may result in irreversible heart damage. Additionally, severe aortic stenosis can increase the risk of sudden death. Therefore, healthcare providers may advise against delaying treatment.

How is aortic stenosis diagnosed?
- Cardiac Surgeons diagnose Aortic stenosis through various tests and examinations.
- Cardiologists may listen to the patient's heart using a stethoscope to detect abnormal sounds or murmurs.
- An echocardiogram, a type of ultrasound, may be used to visualize the heart and assess the condition of the aortic valve.
- Other imaging tests, such as a chest X-ray or a cardiac MRI, may also be used to diagnose aortic stenosis.
- A cardiac catheterization, which involves inserting a thin tube into the blood vessels to access the heart, may be used to confirm the diagnosis and assess the severity of the condition.
- An electrocardiogram (ECG) may detect any irregularities in the heart's electrical activity.
- Genetic testing may be recommended, especially for patients with a family history of aortic stenosis or other heart valve conditions.
Is it possible to cure aortic stenosis?
- Medication or lifestyle changes alone cannot cure aortic stenosis.
- However, treatments are available to manage the symptoms and slow down the progression of the disease.
- Doctors prescribe medication to relieve symptoms or manage related conditions, such as high blood pressure or heart failure.
- Surgery, such as aortic valve replacement or balloon valvuloplasty, may be necessary to treat severe cases of aortic stenosis.
- Aortic valve replacement is a surgical procedure that involves replacing the damaged valve with a new one. The new valve can be either mechanical or biological.
- Balloon valvuloplasty is a less invasive procedure that involves inserting a catheter with a balloon on its tip into the narrowed valve and inflating it to widen the valve opening.
- Transcatheter aortic valve replacement (TAVR) is a newer, minimally invasive procedure that involves inserting a new valve through a small incision in the groin or chest and guiding it to the heart using a catheter. EXPERTS recommend TAVR for patients who are not candidates for traditional surgery.
What will be the proper guidance to the patient?
- Talking to your cardiologist sooner about your risk for aortic stenosis, especially if you have symptoms, can significantly impact your life.
- Aortic stenosis is a complex condition, but with advances in surgical and catheter-based techniques, more treatment options are available with reason.
- Surgical treatments, such as aortic valve replacement or balloon valvuloplasty, can help manage the condition and improve symptoms.
- Catheter-based procedures, such as transcatheter aortic valve replacement (TAVR), can also be effective for those not candidates for surgery.
- These treatment options have enormously improved outcomes, especially for older patients or those with other underlying health conditions that may complicate their care.
