摘要：
A heart valve anchor apparatus may include a body having a proximal portion and a distal portion. The body may include a first radially expandable portion at the proximal portion of the body, a second radially expandable portion at the distal portion of the body, and a root portion extending from the first radially expandable portion to the second radially expandable portion, the root portion having an outer extent. The first radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. The second radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. In an unstressed configuration, the body may define a longitudinal centerline that extends away from a plane tangent to the root portion.
