Beschreibung
Zusammenfassung:	A method of valve implantation includes installing a leaflet lasso on a host leaflet assembly at an implantation site within a patient's body. The method includes positioning an expandable prosthetic heart valve in a crimped state within a central region of the host leaflet assembly. The method includes radially expanding the prosthetic heart valve to a working diameter. During at least a portion of radially expanding the prosthetic heart valve, the prosthetic heart valve contacts a central lasso portion of the leaflet lasso and applies a radial force to the central lasso portion that results in folding of at least one leaflet of the leaflet assembly.
