Morphological modification of the aortic annulus in tricuspid and bicuspid valves after aortic valve reimplantation: an electrocardiography-gated computed tomography study†

Abstract

There is a possible gradual spectrum in terms of shape, from native TAVs, to type 1 BAVS to type 0 BAVs. These differences are eliminated in the postoperative phase, suggesting an active role of the annuloplasty on the geometry of the aortic annulus. The preoperative analysis showed a complete inelasticity of BAVs, which was partly restored in the postoperative phase.
