Surgical Bicuspid Aortic Valve Replacement with Rapid Deployment Aortic Valve Prosthesis in Sievers Type 0 versus Sievers Type 1 Morphology

Background: The use of rapid deployment (RD) surgical aortic valve replacement (SAVR) in bicuspid aortic valve morphology (BAV) faces several challenges due to annular asymmetry and massive calcification of the leaflets. Especially BAV with Sievers type 0 morphology, which has only two opposed raphes, and a mostly elliptical annulus must be reconstructed with caution. Nevertheless, RD SAVR might be a feasible approach for all types of BAV by following specific implantation strategies. The study aimed for retrospective feasibility analysis and comparison of RD SAVR in different bicuspid morphologies.
