Beschreibung
Zusammenfassung:	Methods for generating aortic heart valve leaflets are disclosed wherein the aortic sinus surfaces (the inner surfaces of the sinuses of Valsalva) are used as a template to generate geometric representations of replacement aortic heart valve leaflets. As such, sinus-matched replacement leaflets can be sized and shaped according to the patient-specific geometry of the aortic root. Patient-specific aortic valve assemblies based on aortic root and sinus geometry are also described. Methods for estimating the coaptation area of a sinus-matched valve and assessing whether the valve is functionally competent for implantation are described.
