Key result
Transoesophageal echocardiography detected vegetations in 48% of patients with suspected endocarditis versus 28% with transthoracic echocardiography, and identified 100% of confirmed cases vs 63%.
Why the study?
Does transoesophageal echocardiography improve the detection of vegetations compared to transthoracic echocardiography in patients with suspected infective endocarditis?
Population
96 patients (64 men, 32 women; age range 17–84 years) with clinically suspected infective endocarditis

TEE may be preferred for vegetation detection in suspected IE; leaves open impact on management and outcomes.

Does transoesophageal echocardiography improve the detection of vegetations compared to transthoracic echocardiography in patients with suspected infective endocarditis?
Absolute Event Rate: 48% vs 28%
Transoesophageal echocardiography is significantly superior to transthoracic echocardiography for detecting vegetations in suspected infective endocarditis, particularly for lesions smaller than 10 mm.
Drexler et al. (1987) conducted an observational in clinically suspected infective endocarditis (n=96). Transoesophageal echocardiography (TEE) vs. Transthoracic echocardiography (TTE) was evaluated on Detection of vegetations. Transoesophageal echocardiography detected vegetations in 48% of patients with suspected endocarditis versus 28% with transthoracic echocardiography, and identified 100% of confirmed cases vs 63%.
