An expandable support member comprising an ECM composition that is configured to engage an interior region of a prosthetic valve and capable of transitioning from a pre-deployment configuration, where the support member is capable of being positioned at an interior valve region of the valve when the valve is disposed at a cardiovascular valve structure, to a post-deployment configuration when the support member absorbs a first bodily fluid and expands, where an outer surface region of the valve is placed in intimate contact with host cardiovascular tissue of the cardiovascular structure at a first position and seals perivalvular leaks present at the first cardiovascular structure position.
