Viridans streptococcal endocarditis.
Although responsible for a declining proportion of cases of infective endocarditis, viridans streptococci remain the commonest cause and accounted for 30% of our cases seen in Huntsville, Alabama. Usually viridans streptococcal endocarditis is associated with dental manipulation or infection and underlying heart disease but both conditions were not common in our series. Similar to the experience of other investigators, our patients exhibited a subacute course with fever, dyspnea, weight loss and heart murmur. Echocardiography, reported useful in detecting vegetations in one series, was not a sensitive diagnostic tool in our patients. We confirmed the low relapse rate and mortality rate associated with earlier reports of viridans streptococcal endocarditis but observed a high rate of complications, as noted in a recent series.
