A 25-year-old member asked:

is the bicuspid valve opened or closed when the left atrium contracts?

Open: The bicuspid or mitral valve would be open when the left atrium contracts. It opens during diastole (heart is relaxed) and blood is flowing from the atrium to the ventricle. The contraction of the left atrium results in the valve opening wider and an increase in that flow.
Dr. Bennett Werner
Cardiology 44 years experience
Open: Open. In humans, and in clinical medicine, the biscupid valve is called the mitral valve.

How do aortic valves become fused?

Dr. Francis Uricchio
Cardiology 38 years experience
Birth/Inflammation: Valve leaflets can be fused at birth due to birth defect. They can also become fused later in life due to inflammation such as rheumatic heart disease. The aortic valve may degenerate over time due to wear and tear. This is probably a type of low level but progressive inflammation.

What happens if someone's bicuspid valve does not close properly?

Dr. John Wylie

Aortic insufficiency: When an aortic valve (bicuspid or a normal tricuspid valve) does not close properly, insufficiency or regurgitation ("leaking") results. When mild, this does not have clinical effects, but when severe it can compromise cardiac function.

I sure agree. Also, will need antibiotics prior to dental procedures that may cause bleeding.

Long standing aortic insufficiency with a significant backward flow gradually enlarges the heart eventually weakening it and causing heart failure. When the situation is clearly progressing toward that end, replacement of the aortic valve is generally done to stop the progression to heart failure.
