Classification
Bicuspid aortic valves may assume three different types of configuration:
"Real" bicuspid valves with two symmetric leaflets
A tricuspid architecture with a fusion of two leaflets
A tricuspid architecture with a fusion of three leaflets

Treatment
Complications stemming from structural heart issues are most often treated through surgical intervention, which could include aortic valve replacement, or balloon valvuloplasty. Prognosis
BAV frequently leads to significant complications in over one-third of affected individuals which often lead to significant morbidity and mortality. Notable complications of BAV include narrowing of the aortic valve opening, backward blood flow at the aortic valve, dilation of the ascending aorta, and infection of the heart valve.If aortic regurgitation and dilation of the ascending aorta are noted in someone, they should undergo yearly surveillance with transthoracic echocardiograms if the aortic root measures 4.5 centimeters or greater in diameter. Epidemiology
Bicuspid aortic valves are the most common cardiac valvular anomaly, occurring in 1–2% of the general population. It is twice as common in males as in females.Bicuspid aortic valve is a heritable condition, with a demonstrated association with mutations in the NOTCH1 gene.
These individuals are also at far greater risk of severe hypoglycemia.While the exact cause of hypoglycemic unawarenss is still under research, it is thought that these individuals progressively begin to develop fewer adrenergic-type symptoms, resulting in the loss of  neuroglycopenic-type symptoms. Neuroglycopenic symptoms are caused by low glucose in the brain, and can result in tiredness, confusion, difficulty with speech, seizures, and loss of consciousness. Adrenergic symptoms are caused by the bodys reaction to low glucose in the brain, and can result in fast heart rate, sweating, nervousness, and hunger. See section above on Signs and Symptoms for further explanation of neuroglycopenic symptoms and adrenergic symptoms. In terms of epidemiology, hypoglycemic unawarenss occurs in 20-40% of type 1 diabetics. Other causes
Other causes of hypoglycemia in diabetics include the following:

Fasting, whether it be a planned fast or overnight fast, as there is a long period of time without glucose intake
Exercising more than usual as it leads to more use of glucose, especially by the muscles
Drinking alcohol, especially when combined with diabetic medications, as alcohol inhibits glucose production
Kidney disease, as insulin cannot be cleared out of circulation well

Non-diabetics
Serious illness
Serious illness may result in low blood sugar. Severe disease of many organ systems can cause hypoglycemia as a secondary problem. Hypoglycemia is especially common in those in the intensive care unit or those in whom food and drink is withheld as a part of their treatment plan.Sepsis, a common cause of hypoglycemia in serious illness, can lead to hypoglycemia through many ways.
