Frequency of intracranial aneurysms and sub-arachnoid hemorrhage is significantly lesser in bicuspid aortic valve than aortic coarctation

Background Bicuspid aortic valve(BAV) is common. Some studies suggest that all BAV patients require screening for intracranial aneurysm(IA) in order to prevent sub-arachnoid hemorrhage(SAH). Aortic coarctation(CoA) carries high-risk of both IA and SAH. Using a nationally-representative population, we assessed the frequency of IA and SAH in admissions with BAV-without-CoA versus admissions with CoA(with or without BAV). Methods Between 2000 and...
