What will a stenotic aortic valve increase?
Andrew Campbell When the aortic valve opening is narrowed, your heart must work harder to pump enough blood into the aorta and to the rest of your body. The extra work of the heart can cause the left ventricle to thicken and enlarge.
What diseases can lead to insufficient aortic valve?
Causes
- Congenital heart valve disease.
- Narrowing of the aortic valve (aortic stenosis).
- Inflammation of the lining of the heart’s chambers and valves (endocarditis).
- Rheumatic fever.
- Other diseases.
- Tear or injury of the body’s main artery (aorta).
Can you live a long life with a bicuspid aortic valve?
Many people can live with a bicuspid aortic valve for their entire life, but there are those who may need to have their valve surgically replaced or repaired. When people are born with a bicuspid aortic valve, the bicuspid valve typically functions well throughout childhood and early adulthood.
What is considered critical aortic stenosis?
Cardiac catheterization is indicated when the angina of aortic stenosis may be due to coexistent coronary disease or when aortic valve replacement is indicated….Diagnosis – Aortic Stenosis.
| Mean gradient (mmHg) | Aortic Valve Area (cm2) | |
|---|---|---|
| Mild | 15-25 | > 1.5 |
| Moderate | 25-40 | 1.0-1.5 |
| Severe | > 40 | 0.7-1.0 |
| Critical | N/A | < 0.7 |
When should you have aortic valve replacement?
The aortic valve may need to be replaced for 2 reasons:
- the valve has become narrowed (aortic stenosis) – the opening of the valve becomes smaller, obstructing the flow of blood out of the heart.
- the valve is leaky (aortic regurgitation) – the valve allows blood to flow back through into the heart.
Do bioprosthetic aortic valves have bleeding risks?
Mechanical valves used for aortic valve replacement (AVR) continue to be associated with bleeding risks because of anticoagulation therapy, while bioprosthetic valves are at risk of structural valve deterioration requiring reoperation.
When is anticoagulation indicated for patients with bioprosthetic aortic valves?
For patients with bioprosthetic aortic valves, anticoagulation for 3-6 months is indicated in patients with established risk factors, such as atrial fibrillation.
Are patients with bioprosthetic mitral valves at higher risk for thrombotic complications?
Finally, even though fewer data are available, patients with bioprosthetic mitral valves appear to be at higher risk for thrombotic complications, and routine anticoagulation for 3-6 months is recommended.
What are the risks of bioprosthetic heart valves for SVD?
The main risk with bioprosthetic valves is reoperation for SVD due to the limited durability of bioprosthetic valves ( Figure 1 ).
