    Area of Science:

    • Cardiovascular Surgery
    • Cardiac Pathology
    • Prosthetic Heart Valves

    Context:

    • Paravalvular insufficiency (PVI) is a significant complication following prosthetic heart valve replacement.
    • Understanding PVI morphology is crucial for patient management and surgical outcomes.
    • A large cohort of 5,113 prosthetic heart valve replacements provides a robust dataset for analysis.

    Purpose:

    • To investigate the morphological characteristics of paravalvular insufficiency.
    • To analyze the hemodynamic and functional status of patients diagnosed with PVI.
    • To review specific features and outcomes of reoperations for PVI.

    Summary:

    • Analysis of 5,113 prosthetic heart valve replacements revealed key morphological features of paravalvular insufficiency.
    • Clinical, non-invasive, and invasive data elucidated hemodynamic disorders and functional impairments in PVI patients.
    • Outcomes of 35 repeat surgeries for PVI were examined, showing a 5-year survival rate of 26.4%.

    Impact:

    • Highlights the critical nature of paravalvular insufficiency as a complication.
    • Emphasizes the importance of preventative strategies to mitigate PVI incidence and severity.
    • Provides insights into the long-term prognosis and management challenges associated with PVI.
