Echocardiography predicts embolic events in infective endocarditis
Key result
Highly mobile vegetations over 15 mm on TEE predict an ~83% embolic event rate.
- P<0.001
- n=178
Why the study?
The value of echocardiography in predicting embolic events in patients with infective endocarditis remained controversial, with conflicting evidence on whether large and mobile vegetations increase embolic risk.
Population
178 consecutive patients with definite infective endocarditis according to Duke criteria
Comparison
Echocardiographic characteristics (localization, size, mobility) of vegetations
Design
Observational study

Implication
May refine embolic risk stratification by TEE in IE; leaves open whether vegetation thresholds should guide therapy.
Key Points
- Determine whether echocardiographic features can predict the occurrence of embolic complications in infective endocarditis.
- Evaluation of cardiac structures and infected valve vegetations using echocardiographic imaging.
- Assessment of vegetation characteristics in relation to subsequent systemic embolic events.
- Echocardiographic parameters significantly predict the probability of future embolic episodes.
- Specific anatomical and kinematic properties of cardiac vegetations identify patients at elevated risk for systemic embolization.

Cite This Study
Salvo et al. (2001) conducted an observational in Infective endocarditis (n=178). Large (>15 mm) and severely mobile vegetations on transesophageal echocardiography vs. Absence of large and severely mobile vegetations was evaluated on Embolic events (p=<0.001). Vegetation length and mobility on transesophageal echocardiography independently predicted embolic events, which occurred in 83% of patients with vegetations >15 mm and severe mobility (p<0.001).
