[Diagnostic contribution of transesophageal echocardiography in infectious endocarditis. Apropos of 101 cases].
One hundred and one consecutive patients with infectious endocarditis were examined by transthoracic (TTE) and transoesophageal echocardiography (TEE). There were 71 cases of endocarditis on native valves (N) and 30 cases of endocarditis on prosthetic valves (P). The detection of vegetations was significantly greater by TEE (93%), than by TEE (73%) on native valves but the rate of detection of endocarditis on prosthetic valves was low and identical with both methods. Out of a total of 18 abscesses, only 6 were detected by TEE compared with 15 by TEE. There were 3 false negative results by TEE: small anterior abscesses marked by the prosthesis or aortic calcifications. In addition, TEE demonstrated 3 perforations and 2 mycotic aneurysms of the mitral valve. The lesions were confirmed anatomically in 48 cases. The sensitivity of TEE was 94% and the specificity was 84.5%; the negative predictive value was 87.5%. These results show that TEE is significantly superior in the detection and morphological analysis of vegetations. It is the method of choice for the diagnosis of abscesses, especially in prosthetic valve endocarditis.
