Your aortic valve is one of your four heart valves. It connects the left side of your heart with your aorta. Your aorta is the large artery that carries oxygen-rich blood to your body. Your aortic valve controls blood flow into your aorta and keeps blood moving in one direction.Feb 23, 2022
What is the main function of the aortic valve?
Aortic Valve Opens to allow blood to leave the heart from the left ventricle through the aorta and the body. Prevents the backflow of blood from the aorta to the left ventricle.
What happens if the aortic valve is blocked?
In aortic valve stenosis, the aortic valve opening is narrowed (top row). The narrowing requires increased pressure within the heart to pump blood across a smaller opening. Eventually this reduces the heart's ability to pump blood to the body.
Where are aortic valves located?
aortic valve: located between the left ventricle and the aorta.
What are the symptoms of a failing aortic valve?
As aortic valve regurgitation worsens, signs and symptoms may include:Shortness of breath with exercise or when you lie down.Fatigue and weakness, especially when you increase your activity level.Heart murmur.Irregular pulse (arrhythmia)Lightheadedness or fainting.More items...•
Can aortic valve be replaced without open-heart surgery?
Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure to replace a narrowed aortic valve that fails to open properly (aortic valve stenosis). In this procedure, surgeons insert a catheter into the leg or chest and guide it to the heart.
What is the life expectancy of a person with aortic stenosis?
Without treatment, a person's life expectancy with aortic stenosis after symptoms develop is 1–3 years. Around 50–68% of symptomatic people die within 2 years. Often, they die suddenly. However, aortic valve replacement surgery significantly increases life expectancy.
How long does it take to recover from aortic valve replacement?
After an aortic valve replacement, you'll usually need to stay in hospital for about a week. The time it takes to fully recover varies depending on factors like your age and overall health. Your breastbone will usually heal in about 6 to 8 weeks, but it may be 2 to 3 months before you feel your normal self again.
Which heart valve is the most difficult to replace?
The aortic valve is the most common valve to be replaced. The mitral valve is the most common valve to be repaired. Only rarely is the tricuspid valve or the pulmonic valve repaired or replaced.
What is the success rate of aortic valve replacement surgery?
Survival rates of 84% to 93%, 79% to 82%, and 57% to 82% were reported after isolated AVR at 1, 3, and 5 years, respectively. After combined AVR and CABG, the survival rates were 76% to 92%, 65% to 79%, and 47% to 78% at 1, 3, and 5 years, respectively.
How long can you live with a leaky aortic valve?
For aortic valve-replacement patients in general, this loss was 1.9 years. Without treatment, however, the mean survival for these patients is two to three years.
What are the signs of needing a heart valve replacement?
Why might I need heart valve repair or replacement surgery?Dizziness.Chest pain.Breathing difficulties.Palpitations.Edema (swelling) of the feet, ankles, or abdomen (belly)Rapid weight gain due to fluid retention.
What happens if aortic valve is not replaced?
Aortic Valve Problems Or, it could be from wear and tear over the years, or because of another health condition, like a heart infection. Those problems can cause shortness of breath, chest pain, dizziness, fainting, and other symptoms. If you don't get the valve replaced, it can be life-threatening.
What would happen if the aortic valve was damaged?
The aortic valve helps keep blood flowing in the correct direction through the heart. A damaged or diseased aortic valve can affect blood flow to the rest of the heart and body.
What are the end stages of aortic stenosis?
If left untreated, severe aortic stenosis can lead to heart failure. Intense fatigue, shortness of breath, and swelling of your ankles and feet are all signs of this. It can also lead to heart rhythm problems (arrhythmias) and even sudden cardiac death.
How do you fix aortic valve stenosis?
Aortic valve replacement is often needed to treat aortic valve stenosis. In aortic valve replacement, your surgeon removes the damaged valve and replaces it with a mechanical valve or a valve made from cow, pig or human heart tissue (biological tissue valve).

Bicuspid aortic valve (aka BAV) is a form of heart disease in which two of the leaflets of the aortic valve fuse during development in the womb resulting in a two-leaflet (bicuspid) valve instead of the normal three-leaflet (tricuspid) valve. BAV is the most common cause of heart disease present at birth and affects approximately 1.3% of adults.

An aortic aneurysm is an enlargement (dilatation) of the aorta to greater than 1.5 times normal size. They usually cause no symptoms except when ruptured. Occasionally, there may be abdominal, back, or leg pain. The prevalence of abdominal aortic aneurysm ("AAA") has been reported to range from 2 to 12% and is found in about 8% of men more than 65 years of age.

· Three main problems can arise when a valve doesn’t work properly: The valve doesn’t close completely, allowing blood to leak back into the heart. This is known as regurgitation. The valve doesn’t open fully, which reduces blood flow out of the heart. This is known as stenosis. An infection damages or destroys the valve, known as endocarditis.
