    Routine cardiac catheterization before valve replacement surgery is often unnecessary. Clinical assessment alone is sufficient for most patients, ensuring similar outcomes and avoiding invasive procedures when not clinically indicated.

    Area of Science:

    • Cardiology
    • Cardiac Surgery

    Background:

    • Valvular heart disease management often involves invasive cardiac catheterization.
    • The necessity of routine catheterization prior to valve replacement is debated.

    Purpose of the Study:

    • To evaluate the necessity of routine cardiac catheterization before valve replacement surgery.
    • To compare outcomes between patients who underwent valve replacement with and without prior catheterization.

    Main Methods:

    • Retrospective analysis of 1978 patient data undergoing valve replacement.
    • Comparison of outcomes in three groups: no catheterization, elective catheterization, and prior catheterization elsewhere.
    • Analysis included age, sex, symptoms, cause of disease, operative mortality, and 2-year follow-up.

    Main Results:

    • 184 patients had valve replacement without invasive studies; 59 had elective catheterization; 62 had prior catheterization.
    • No significant differences in preoperative diagnosis, operative mortality, or 2-year survival and symptom status were observed between groups.
    • No uncorrected valve lesions were found in patients not undergoing catheterization.

    Conclusions:

    • Routine cardiac catheterization is not necessary for all patients undergoing valve replacement.
    • Catheterization can be reserved for specific indications, optimizing resource utilization.
    • Clinical and noninvasive assessments are adequate for guiding surgical decisions in many valvular heart disease cases.
