Silent mitral stenosis (report of 8 cases)

: We studied eight cases of mitral "mute" stenosis we had discovered through echocardiogram, and analysed its clinical behaviour, the various findings in exploration, and electrocardiographic, radiologic, phonomecanocardiographic and echocardiographic changes. We mention the most notable signs for the suspected diagnosis of this kind of stenosis and the importance they have in the alleviation of this illness--frequently a very severe one, through surgical treatment. When mitral stenosis is not recognized in time through a precise diagnosis, turns to be a potentially lethal illness a short time after being diagnosed as a pulmonary arterial hypertension. We highly recommend the use of echocardiography for the diagnosis of mitral "mute" stenosis, because it has proved to be a inocuous, easy to obtain and very sensible way of diagnosing.
