Understanding Aortic Stenosis: Causes, Symptoms, and Treatment Options

Aortic stenosis is a condition characterized by the narrowing of the aortic valve opening, which restricts blood flow from the left ventricle to the aorta and onward to the rest of the body. This condition can lead to significant health problems if left untreated.

FAQs About Aortic Stenosis

What is Aortic Stenosis? Aortic stenosis is a heart condition where the aortic valve becomes narrowed, reducing blood flow from the heart to the rest of the body. This can cause various health issues if not properly managed.

Why Does Aortic Stenosis Occur? Aortic stenosis typically occurs due to a few key reasons:

• Age-related calcification: Over time, calcium deposits can build up on the valve, causing it to stiffen and narrow.
• Congenital heart defect: Some people are born with a bicuspid aortic valve instead of the usual tricuspid valve, making them more susceptible to stenosis.
• Rheumatic fever: This inflammatory disease can damage the aortic valve and lead to stenosis later in life.
• Radiation therapy: Radiation treatments for cancer in the chest area can sometimes cause long-term damage to the heart valves.

What Are the Risk Factors for Aortic Stenosis? Several factors can increase the risk of developing aortic stenosis, including:

• Age: The risk increases as people get older, particularly after the age of 60.
• High blood pressure: Chronic hypertension can contribute to valve damage.
• High cholesterol: Elevated cholesterol levels can accelerate calcification and plaque buildup on the valve.
• Diabetes: This condition can contribute to atherosclerosis, affecting the heart valves.
• Smoking: Tobacco use is a significant risk factor for many cardiovascular diseases, including aortic stenosis.

What Are the Symptoms of Severe Aortic Stenosis? As aortic stenosis progresses, it can cause various symptoms, particularly when it becomes severe. These symptoms include:

• Chest pain or tightness: Often occurring during physical activity.
• Shortness of breath: Particularly during exertion or lying down.
• Fatigue: A general feeling of tiredness and reduced stamina.
• Heart palpitations: A sensation of rapid, fluttering, or pounding heartbeats.
• Dizziness or fainting: Especially during activity due to reduced blood flow.

What Are the Treatment Options for Severe Aortic Stenosis? When aortic stenosis becomes severe, medical intervention is usually necessary. Treatment options include:

• Medications: Although they cannot cure aortic stenosis, medications can help manage symptoms and improve heart function.
• Aortic valve replacement: Surgical replacement of the aortic valve can significantly improve outcomes. This can be done through open-heart surgery or minimally invasive techniques like transcatheter aortic valve replacement (TAVR).
• Balloon valvuloplasty: This procedure involves inserting a catheter with a balloon at the tip into the narrowed valve. When inflated, the balloon widens the valve opening. However, this is usually a temporary measure.
• Lifestyle changes: Patients are often advised to make heart-healthy lifestyle changes, such as quitting smoking, eating a balanced diet, and engaging in regular physical activity as tolerated.

Can Aortic Stenosis Be Prevented? While you cannot prevent age-related changes or congenital heart defects, you can reduce your risk of aortic stenosis by managing other risk factors:

• Maintain a healthy blood pressure and cholesterol level.
• Manage diabetes effectively.
• Avoid smoking.
• Follow a heart-healthy diet and exercise regularly.
