    Echocardiography detects bacterial endocarditis vegetations in most patients. Large vegetations or valve issues may necessitate surgery, especially with heart failure or embolic events.

    Area of Science:

    • Cardiology
    • Infectious Diseases
    • Medical Imaging

    Background:

    • Bacterial endocarditis is a serious infection affecting heart valves.
    • Echocardiography is a key diagnostic tool for endocarditis.
    • Vegetations are a hallmark of bacterial endocarditis.

    Purpose of the Study:

    • To evaluate the role of echocardiography in diagnosing and managing bacterial endocarditis.
    • To identify echocardiographic findings predictive of complications and surgical intervention.

    Main Methods:

    • Retrospective analysis of patients with clinical bacterial endocarditis.
    • Utilized echocardiography to detect and characterize vegetations and valve damage.
    • Correlated echocardiographic findings with clinical outcomes and need for surgery.

    Main Results:

    • Echocardiography detected vegetations in 55-80% of patients.
    • Large left-sided vegetations correlated with increased embolic risk.
    • Multiple valve involvement indicated progressive deterioration.
    • Serial echocardiography identified complications like leaflet disruption and abscesses.
    • Vegetations did not regress with antibiotics.

    Conclusions:

    • Echocardiography is crucial for diagnosing bacterial endocarditis and assessing complication risk.
    • Key indications for surgery include heart failure, embolic events, and persistent sepsis.
    • Echocardiographic findings guide management decisions, often obviating the need for cardiac catheterization.
