Bicuspid aortic valve

Bicuspid aortic valve

• occurs in 1-2% of the population
• usually asymptomatic in childhood
• the majority eventually develop aortic stenosis or regurgitation
• associated with a left dominant coronary circulation (the posterior descending artery arises from the circumflex instead of the right coronary artery) and Turner's syndrome
• around 5% of patients also have coarctation of the aorta

• aortic stenosis/regurgitation as above
• higher risk for aortic dissection and aneurysm formation of the ascending aorta
