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. ## Claims ### Claim at position 1 1-78.
