Aortic annulus size and shape were analyzed in computed tomography angiography after a reimplantation procedure in patients with bicuspid and tricuspid aortic valves. Prior to surgery, elliptic shape was observed in tricuspid valves and more circular shape in bicuspid valves. After reimplantation, there was no difference between groups with similar roundness regardless of valve morphology. The authors concluded that annuloplasty plays an active role on the geometry of the aortic annulus.
