Is cardiac catheterisation necessary before valvular surgery?

P H Wong, J S Chow, W W Chen

    The Medical Journal of Australia
    |October 16, 1982
    PubMed
    Summary

    Cardiac catheterization is often unnecessary for patients undergoing valvular heart surgery. Clinical assessment and echocardiography provide adequate preoperative evaluation, leading to comparable outcomes and low mortality in surgical candidates.

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Diagnostic Imaging

    Background:

    • Cardiac catheterization was a standard preoperative assessment for valvular heart surgery.
    • Non-invasive methods like echocardiography have advanced diagnostic capabilities.

    Purpose of the Study:

    • To evaluate the necessity of cardiac catheterization in patients undergoing valvular operations.
    • To compare surgical outcomes between patients assessed with and without cardiac catheterization.

    Main Methods:

    • Retrospective analysis of 269 patients undergoing valvular operations between January 1980 and June 1981.
    • Group 1: 178 patients assessed with cardiac catheterization (conventional approach).
    • Group 2: 91 patients assessed with clinical and non-invasive methods (echocardiography) only.

    Main Results:

    • No significant differences in major clinical characteristics between the two groups.
    • Preoperative assessment accuracy was high in both groups, with only minor discordance in two catheterized patients.
    • Hospital mortality was low and comparable between the catheterized and non-catheterized groups.

    Conclusions:

    • Cardiac catheterization is not essential for the majority of patients undergoing valvular heart surgery.
    • Clinical evaluation and non-invasive testing, including echocardiography, are sufficient for preoperative assessment.
    • This approach can streamline patient management without compromising surgical outcomes or safety.
