Occluder stop design may influence mitral valve cavitation risk; leaves open clinical relevance for valve selection or outcomes.
In vitro testing of mechanical mitral valves reveals that the occluder stop design is the most critical factor for cavitation initiation, which can occur below normal physiological loading rates.
Lee et al. (1994) studied this question. Mechanical mitral heart valve designs was evaluated on Cavitation initiation sources and dynamics. In vitro testing of nine mechanical mitral heart valves revealed that the occluder stop design is the most critical factor for cavitation initiation.
