Key result
TEE detects infective endocarditis with ~94% sensitivity, vastly outperforming TTE.
Why the study?
The study was conducted to compare the diagnostic value of transesophageal versus transthoracic echocardiography in patients with suspected infective endocarditis.
Does transesophageal echocardiography improve diagnostic sensitivity and specificity compared to transthoracic echocardiography in patients with suspected infective endocarditis?
Population
62 patients with 66 episodes of suspected endocarditis
Comparison
Transesophageal echocardiography vs transthoracic echocardiography
Design
Prospective paired comparative study with blinded observer interpretation

Does transesophageal echocardiography improve diagnostic sensitivity and specificity compared to transthoracic echocardiography in patients with suspected infective endocarditis?
Absolute Event Rate: 94% vs 44%
p-value: p=<0.01
Transesophageal echocardiography provides significantly higher diagnostic sensitivity than transthoracic echocardiography for suspected infective endocarditis.
Shively et al. (1991) conducted an observational in Suspected infective endocarditis (n=62). Transesophageal echocardiography vs. Transthoracic echocardiography was evaluated on Diagnostic sensitivity for infective endocarditis (p=<0.01). Transesophageal echocardiography was significantly more sensitive than transthoracic echocardiography for diagnosing infective endocarditis (94% vs 44%, p<0.01) with 100% specificity.
