A prosthetic heart valve comprises a collapsible and expandable support frame comprising a longitudinal axis. The frame comprises a first circumferential undulating structure defining an outflow end of the frame, and a second circumferential undulating structure spaced apart from the first circumferential undulating structure. The frame also comprises a plurality of struts longitudinally aligned with the longitudinal axis of the frame, and connecting the first circumferential undulating structure to the second circumferential undulating structure. Each strut of the plurality of struts comprises a first end terminating at a trough of the first circumferential undulating structure, and a second end terminating at a peak of the second circumferential undulating structure. The prosthetic heat valve also comprises a biological tissue valve coupled to the frame. The prosthetic heart valve is configured to be collapsed for introduction into a patient using a catheter and to be expanded for deployment at an implantation site.
