To the Editor:

We are investigating the closing sounds of bi-leaflet mechanical heart valves (MHVs) for the early detection of valve dysfunction. Bi-leaflet MHVs are known to generate a typical "double click" due to the asynchronous closure of the leaflets. A simple phonographic analysis allows checking the presence of "double clicks" in a normally functioning MHV; if the signal, monitored over the time domain, lacks "double clicks" (or a sufficient number thereof), the hampered mobility of one leaflet can be hypothesised, thus suggesting further analyses because this event can be due to endothelial pannus growth, thromboembolic deposition on . . .
