Aortic aneurysms with tricuspid aortic valve have more degeneration than unicuspid aortic valve aneurysms

OBJECTIVES The unicuspid aortic valve (UAV) is a rare cardiac malformation and is associated with the formation of ascending aortic aneurysms. To characterize its associated aortic wall changes, normal and aneurysmatic ascending aortic wall specimens were analysed, focusing on the potential mechanisms of aneurysm formation. Patients with tricuspid aortic valve (TAV) served as controls. METHODS In a retrospective observational study, 74 specimens...
