In the past, the most common risk<unk> for aortic valvular disease had been the rheumatic fever, with subsequent fibrosis of the scarred valve then leading to retraction of the aortic valve cusps and prevention of their apposition during diastole. In the modern era, a more common risk<unk> for acquired aortic regurgitation is degenerative disease of the aorta and aortic valve in which case there is calcification and fibrosis of the cusps. Infective endocarditis remains an important risk<unk> and cause of aortic regurgitation. Congenital conditions such as congenital bicuspid aortic valve or a ventricular septal defect can also result in aortic regurgitation. Patients with bicuspid aortic valve are at increased risk of developing aortic dissection.
