Abstract
ABSTRACT Anatomical and anti-anatomical placement of a prosthetic mechanical valve in mitral position has been described in the literature. In mitral position, it is preferred to place the tiltingdisk valve with its large orifice directed posteriorly, which is called as “anatomical position.” We report an incident wherein a Chitra heart valve prosthesis (CHVP) implanted in anatomical position had limited motion of tilting disk with inadequate angle of opening. This was addressed by rotating the prosthesis occluder mechanism by 180° in situ in such a way that the large orifice was directed anteriorly (anti-anatomical position) and this resulted in the adequate opening of the tilting disk. Transesophageal echocardiography (TEE) played a decisive role in identifying the problem and ensuring adequacy of disk opening after repositioning the prosthesis.
