Detailed explanation-1: -This results in leakage of blood back into the atria from the ventricles in the case of the mitral and tricuspid valves. Or it leaks back into the ventricles in the case of the aortic and pulmonary valves . This can cause the chambers to be overworked because they have to pump the extra blood that was returned.
Detailed explanation-2: -Bicuspid valves may eventually leak (aortic regurgitation) and/or narrow (aortic stenosis). It can be years before BAV causes an issue. Once your valve shows signs of regurgitation or stenosis, your heart is likely working harder to pump blood to the body. The extra work can lead to heart failure.
Detailed explanation-3: -Sometimes, the bicuspid aortic valve is leaky. This lets blood to flow back into the heart when the heart relaxes, instead of flowing forward into the body the way it should. This process is called aortic regurgitation. It can also make the heart work harder.
