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.
经食管超声心动图（ECHO）四原则——即弹性、圆度、高度和方向——指导，我们对植入技术进行了改良，以预防瓣周漏和瓣膜错位，从而使 Perceval 无缝合瓣膜在治疗退行性主动脉瓣狭窄方面得到了越来越多的应用，但由于解剖学方面的挑战，尚未用于治疗 0 型二叶式主动脉瓣先天性病变。
