Transcatheter Heart Valves

A prosthetic heart valve comprising:

• a collapsible and expandable support frame comprising a longitudinal axis, the frame comprising:
• a first circumferential undulating structure defining an outflow end of the frame;
• a second circumferential undulating structure spaced apart from the first circumferential undulating structure;
• and
• 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 comprising:
• 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;
• and
• a biological tissue valve coupled to the frame,
• wherein 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.
