The apparatus includes a substantially annular support member, at least one infra-annular support member securely connected thereto, and at least one anchoring element associated with the at least one infra-annular support member. The at least one anchoring element is configured to securely receive a prosthetic chordae tendineae for attachment to a papillary muscle. The posterior end portion is dimensioned for attachment to a posterior portion of the diseased heart valve annulus. The at least one infra-annular support member is securely connected to the substantially annular support member. The at least one infra-annular support member is dimensioned to extend below at least one of the posterior and anterior valve leaflets and across or behind at least one subvalvular structure.
