Abstract:
The Perceval sutureless valve has gained in popularity for treating degenerative aortic valve stenosis but not for congenital type 0 bicuspid aortic valve owing to anatomic challenges. We modified implant techniques following the four principles of ECHO-an acronym for elasticity, circularity, height, and orientation-to prevent paravalvular leakage and malposition.
