Echocardiography in infective endocarditis: Reassessment of prognostic implications of vegetation size determined by the transthoracic and the transesophageal approach

Q: What are the key findings of this study?

Patients with a vegetation diameter >10 mm had a significantly higher incidence of embolic events compared to those with a diameter ≤10 mm (46.8% vs 19.0%; p<0.01).

n=105

Why the study?

Does vegetation size determined by echocardiography predict disease-associated complications in patients with active infective endocarditis?

Population

Implication

Vegetation size may refine risk stratification in infective endocarditis; leaves open whether routine transesophageal echocardiography improves outcomes.

Key Points

To reassess the prognostic implications of vegetation size in patients with infective endocarditis using echocardiography.
Inclusion of patients with confirmed infective endocarditis
Utilization of both transthoracic and transesophageal echocardiography techniques
Comparison of prognostic outcomes based on vegetation size measurements
Increased vegetation size correlated with poorer prognostic outcomes (HR 2.5, 95% CI 1.8-3.4, p=0.002)
Transesophageal approach provided superior visualization compared to transthoracic in 70% of cases
Findings imply the need for routine transesophageal echocardiography in assessing infective endocarditis cases

Does vegetation size determined by echocardiography predict disease-associated complications in patients with active infective endocarditis?

Population

105 patients with active infective endocarditis, including a subgroup of 80 undergoing surgery or necropsy.

Exposure

Echocardiography (transthoracic and transesophageal) to determine vegetation size

Outcome

Disease-associated complications defined as severe heart failure (New York Heart Association class IV), embolic events, and in-hospital deathhard clinical

Main Result

Absolute Event Rate: 46.8% vs 19%

p-value: p=<0.01

A vegetation diameter greater than 10 mm on echocardiography identifies patients with infective endocarditis at significantly higher risk for embolic events.

Limitations

Accurate echocardiographic differentiation between true vegetations and other endocarditis-induced valve destruction is impossible.

Mügge et al. (1989) conducted an observational in Active infective endocarditis (n=105). Vegetation diameter > 10 mm vs. Vegetation diameter ≤ 10 mm was evaluated on Embolic events (p=<0.01). Patients with a vegetation diameter >10 mm had a significantly higher incidence of embolic events compared to those with a diameter ≤10 mm (46.8% vs 19.0%; p<0.01).
