Abstract:
Objective:To explore the value of echocardiography for diagnosing infectious endocarditis (IE).Methods:A total of 487 patients with cardiovascular implantable electronic devices (CIED) infection treated in our hospital from 2013-01 to 2015-06 were enrolled.Based on symptoms,blood culture and echocardiography,9 patients with suspected IE were further examined by 18F-FDG PET-CT to confirm their diagnosis and classification.Definitive therapy was conducted and the patients were followed-up for 1 year to confirm the diagnostic accuracy of echocardiography on CIED induced IE.Results:3 patients were preliminarily diagnosed for bacteremia since no vegetation was found by echocardiography,while IE was finally diagnosed by PET-CT.2 patients were preliminarily diagnosed for IE by echocardiography presented valvular vegetation,while PET-CT showed no evidence of vegetation;then one of them was diagnosed as bacteremia by positive blood culture and another was diagnosed as non-infection.4 patients were preliminarily diagnosed for IE by echocardiography indicated existing vegetation after CIED lead extraction,while PET-CT demonstrated no infection sign in heart chamber and the finally diagnosed was as "non-infectious fibrous residual tissue".According to final diagnosis,definitive therapies were performed to specific patients with at least 1 year follow-up study,no one had new and recurrent infection.Conclusion:Echocardiography had deficiency for diagnosing vegetation in heart chamber especially in suspicious IE patients after CIED lead extraction.It is necessary to make accurate diagnosis with other method for guiding appropriate therapy.
