Does anti-anatomical placement improve tilting disk motion compared to anatomical placement for a Chitra heart valve prosthesis in the mitral position?
Anti-anatomical placement of a tilting-disk mechanical valve in the mitral position may be necessary to ensure adequate disk opening if anatomical placement results in limited motion, with TEE playing a crucial role in assessment.

Anti-anatomical placement may resolve limited disk motion in Chitra mitral prostheses; case report leaves open need for confirmatory studies.
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.

Gadhinglajkar et al. (2017) conducted a case report in Mitral valve replacement (n=1). Anti-anatomical placement of a tilting-disk mechanical valve vs. Anatomical placement was evaluated on Adequate opening of the tilting disk. Rotating a Chitra heart valve prosthesis 180° in situ to an anti-anatomical position resolved limited disk motion observed during initial anatomical placement.
