An apparatus for implantation in an annulus of a tricuspid valve. The apparatus has an anterior annulus aspect, a posterior annulus aspect, and an atrioventricular (AV) node located adjacent the anterior annulus aspect. The apparatus includes an ovoid main body portion. The main body portion has an anterior body segment adapted for placement adjacent the anterior annulus aspect, a posterior body segment located opposite the anterior body portion and adapted for placement adjacent the posterior annulus aspect, and oppositely disposed left and right side body segments extending between the anterior and posterior body segments. At least two valve leaflets are secured within the main body portion and are coaptable to permit unidirectional flow of blood. A cushioned section is attached to the main body portion, coextends with a portion of the main body portion, and is adapted for placement adjacent the AV node.
