Key result
TEE outperforms cardiac CT for detecting valvular infective endocarditis lesions, with an AUC of ~0.88.
Why the study?
The diagnostic agreement between transesophageal echocardiography and cardiac computed tomography in patients with surgically confirmed left-side infective endocarditis was unclear.
Does transesophageal echocardiography improve diagnostic accuracy for detecting valvular and paravalvular lesions compared to cardiac computed tomography in patients with surgically confirmed left-side infective endocarditis?
Comparison
Transesophageal echocardiography vs cardiac computed tomography
Design

TEE preferred over CT for valvular lesions in left-sided IE; leaves open additive role of CT when TEE is inconclusive.

Does transesophageal echocardiography improve diagnostic accuracy for detecting valvular and paravalvular lesions compared to cardiac computed tomography in patients with surgically confirmed left-side infective endocarditis?
Absolute Event Rate: 0.881% vs 0.72%
p-value: p=0.02
Transesophageal echocardiography is superior to cardiac CT for detecting valvular lesions in left-sided infective endocarditis, while both modalities offer similar diagnostic accuracy for paravalvular lesions.
Sifaoui et al. (2020) conducted an observational in Infective endocarditis (n=68). Transesophageal echocardiography (TEE) vs. Cardiac computed tomography (CT) was evaluated on Detection of valvular IE-related lesions (vegetations, erosion) (p=0.02). Transesophageal echocardiography performed better than cardiac CT for detecting valvular infective endocarditis-related lesions (AUC 0.881 vs 0.720, P=0.02).
