1. A tricuspid valve replacement system for use in a heart of a patient, comprising:
a frame; and
a valve coupled to the frame,
wherein the frame comprises;
a central ring,
a plurality of atrial struts extending from a first side of the central ring and terminates at an atrial end of the frame thereby defining an atrial dome, wherein the plurality of atrial struts comprises between two and four atrial struts and
two ventricular struts extending from a second side of the central ring opposite the first side to a ventricular end of the frame;
wherein the frame defines a central axis,
wherein the two ventricular struts terminate separately from each other at the ventricular end of the frame, wherein each of the two ventricular struts bow outwardly away from the central axis so that a maximum distance between the ventricular struts at a point of maximum bowing away from the central axis is greater than a diameter of the central ring,
wherein the valve is coupled to the central ring and the plurality of atrial struts, and
wherein the tricuspid valve replacement system is configured to be placed within the heart of the patient with the atrial dome positioned within a right atrium of the heart, the central ring and valve within an annulus of a native tricuspid valve of the heart, and the plurality of ventricular struts within a right ventricle of the heart so that atrial dome and the plurality of ventricular struts stabilize the tricuspid valve replacement system within the heart in order for the valve to replace function of the native tricuspid valve.
