title: [Significance of echocardiography for the diagnosis and strategy in infectious endocarditis].
abstract: The echocardiographic results of 29 patients--clinically suspected of infective endocarditis--were compared with clinical, intraoperative, histologic, autoptic data and the available outcome of cardiac catheterization. The purpose of this retrospective study was to define the potential valence of echocardiography for planning of therapy and success. Valvular vegetations of different histological ages were established on 35 valves. The sensitivity was 96.3%, the specificity 100% considering this topic. Following visual assessed sonographical intensity of such vegetations echographical floridity was postulated. In 26 vegetations the sensitivity--considering this floridity statement--was 92% and the specificity 86% compared with the results of histology and intraoperative assessment. The type of pathogens and the time interval between beginning of the clinical symptomatic and the echocardiographic procedure were important for the prognosis in this study. In the case of longer latency time prevailed bivalvular vegetations (n = 6) combined with a high mortality. No patient died in the case of univalvular vegetations. The whole group had a mortality of 17.2%. Considering these results using echocardiographic methods an exact identification of vegetations (infective and noninfective) and additional a quantification of subsequent valvular damaging and actual ventricular function is possible. A qualified sonographical technique permits an earlier diagnosis of bacterial endocarditis (especially in the absence of bacteriaemia) and in the followings a more opportune indication for prosthetic valve replacement.
