Complications of Aortic Valve Stenosis

Overview

Aortic stenosis is a condition where the valve of the aorta, which controls blood flow from the heart to the rest of the body, becomes narrow or stiff. This makes it harder for the heart to pump blood through the aorta, which can cause the heart to work harder and can lead to various complications. Some common complications are:

• Decreased exercise tolerance: Since the heart struggles to push blood through the narrowed valve, people often experience shortness of breath and feel tired when they try to be active.
• Heart failure: As aortic valve stenosis gets worse, the heart’s left wall may get thicker because it has to work harder to pump blood through the narrowed valve. This thickening makes the space inside the heart smaller, reducing the amount of blood that can be pumped to the body. This can lead to heart failure. To avoid this, it’s important to treat aortic valve stenosis early
• Pulmonary hypertension: Aortic valve stenosis can also cause pulmonary hypertension, which is a type of high blood pressure affecting the blood vessels in the lungs. This puts extra strain on the heart and can lead to more problems.
• Infective endocarditis: Aortic valve stenosis raises the risk of getting infective endocarditis, which is a bacterial infection of the heart valve or the lining of the heart. To prevent this, it’s important to keep good oral hygiene because mouth infections can spread through the blood and harm the heart valves. It’s also important to treat severe sore throats quickly to prevent rheumatic fever, which can lead to heart valve infections.
• Blood clots: Aortic valve stenosis increases chances of getting blood clots. These clots can travel through the bloodstream and block blood flow in other parts of the body, leading to serious complications such as stroke or organ damage. To prevent blood clots, it is important to follow any prescribed medications or treatments for aortic valve stenosis.
• Sudden death: People with severe symptoms of aortic valve stenosis have a risk of sudden death if they don’t get treatment in time. Getting immediate treatment is important in preventing this serious complication.

To treat these complications if they occur, medical interventions may be necessary:

• Medications:
  • Aortic valve stenosis can be linked to high blood pressure that can be treated with a variety of medications.
  • If you have high cholesterol, taking cholesterol-lowering medications may help slow down the worsening of aortic valve stenosis.
• Heart-healthy lifestyle: If you have no symptoms or only mild ones, maintaining a heart-healthy lifestyle may help prevent the disease from getting worse. This includes:
  • Eating healthy
  • Exercising
  • Managing stress.
• Surgical procedures: If your aortic valve stenosis is moderate to severe or causing symptoms, your doctor may recommend a procedure or surgery to repair or replace the damaged valve.
  • Transcatheter aortic valve replacement (TAVR) is a less aggressive procedure that replaces the damaged valve with one made from animal tissue.
  • Surgical aortic valve replacement (SAVR) is an open-heart surgery that replaces the damaged valve with either a mechanical valve or a valve from a cow, pig, or human donor.
• Valvuloplasty: In some cases, a minimally aggressive procedure called valvuloplasty may be performed to repair your existing valve without replacing it.

It's important to note that these treatment options should be discussed with your doctor as they will determine what course of action is best for your specific situation.
