Background: We sought to compare diagnostic performance of cardiac computed tomography (CCT) with transesophageal echocardiography (TEE) in detecting vegetation and cardiac complications in patients with infective endocarditis (IE).
Methods: A total of 75 patients with definite IE who underwent TEE and CCT were analyzed. Diagnostic performance of two imaging modalities for vegetation and IE related intracardiac complications (valve perforation, valve aneurysm, peri-valvular abscess, pseudoaneurysm, or fistula) were compared.
Results: The detection rate of vegetation in TEE and CCT was 97.3% and 72.0% respectively. The maximum sizes of vegetation by TEE and CCT were well correlated (r=0.627, p<0.001), especially in patients with large vegetation (≥10 mm) suggestive of high risk of systemic embolism. (r=0.678, p<0.001). However, small size vegetation (<10 mm) was underdiagnosed by CCT (52.8%) compared to TEE (94.4%) and the sizes from the two modalities were poorly correlated (r=0.216, p=0.375). Both modalities showed good diagnostic performance for detecting IE related intracardiac complications.
Conclusions: TEE is superior for detecting small sized vegetation. Both TEE and CCT showed good agreement on large size vegetation and valve related complications. CCT had additional role for the diagnosis of coronary artery disease and extracardiac embolic events.
