Abstract
- Nonstructural valvular dysfunction of the mechanical valve is one of the serious complications after valve replacement. It may be caused by various factors; 1) entrapment by pannus, tissue or suture material 2) paravalvular leakage 3) inappropriate sizing or positioning. We have experienced the rare case of nonstructural valvular dysfunction caused by abnormal subaortic pannus ingrowth associated with malposition of mechanical valve. We removed the pannus and successfully performed valve replacement after annulus enlargement procedure(Nicks procedure).
