Abstract:
Five years after the first description of Doppler microembolic signals, both their clinical significance and underlying material remain a matter of debate. It appears certain that MES depend on valve type and position, while their relation to other clinical parameters, including neurological complications, is still unclear. A number of clinical and experimental studies are reviewed, most of which argue towards gaseous embolic material.
