Shunt To Avoid Ventricle Overload And Conduit For Lead Placement

A prosthetic heart valve system for replacing a native right atrioventricular valve, the system comprising:

• a collapsible and expandable anchor frame including:
• a support frame that has a central portion, and an atrial portion and ventricular portion each flared radially outwardly from the central portion, the atrial and ventricular portions sized to sandwich an annulus of the right atrioventricular valve therebetween;
• an atrial sheet coupled to the atrial portion of the support frame and extending radially inwardly to a central aperture in the atrial sheet, the atrial sheet being formed of a material that is substantially impermeable to blood;
• and
• a generally cylindrical leaflet support structure, an inflow end of the leaflet support structure coupled to the atrial sheet;
• wherein the atrial sheet defines an opening positioned radially outside of the leaflet support structure so that blood flowing around an exterior of the leaflet support structure can pass through the opening.
