    Native valve endocarditis surgery outcomes show 70% survival, with early intervention improving results. Abscess presence significantly lowers survival rates in patients undergoing valve replacement.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Infectious Diseases

    Background:

    • Native valve endocarditis (NVE) is a serious infection requiring prompt management.
    • Surgical valve replacement is often necessary for NVE, but outcomes can vary.

    Purpose of the Study:

    • To evaluate the long-term outcomes of surgical valve replacement in patients with NVE.
    • To identify factors influencing survival after valve replacement for NVE.

    Main Methods:

    • Retrospective analysis of 35 patients undergoing 40 valve replacements for NVE between 1972 and 1981.
    • Assessment of hospital mortality, long-term survival, and functional status (New York Heart Association Class).
    • Evaluation of the impact of anular/myocardial abscess and timing of surgery on outcomes.

    Main Results:

    • Hospital mortality was 17%.
    • Overall long-term survival was 70% among survivors.
    • Patients without abscesses and those undergoing early surgery (<4 weeks antibiotic therapy) had significantly better long-term survival (91%) compared to late surgery (>4 weeks, 79%).
    • Anular or myocardial abscess was associated with poor prognosis (25% long-term survival).

    Conclusions:

    • Surgical valve replacement for NVE can achieve favorable long-term survival, particularly when performed early and in the absence of abscess.
    • The presence of anular or myocardial abscess is a critical negative prognostic indicator.
    • Timely surgical intervention is crucial for improving outcomes in native valve endocarditis.
