In vitro findings link cavitation and CO2 to stable bubbles on mechanical valves; leaves open clinical relevance and preventive strategies.
Does cavitation and gas content influence the formation of stable gas bubbles on mechanical heart valves?
In vitro modeling demonstrates that cavitation is an essential precursor to stable gas bubble formation on mechanical heart valves, driven primarily by CO2 concentration.
Lin et al. (2000) studied this question.
