Combined valve replacement and myocardial revascularization.

A S Geha, C K Francis, G L Hammond

    Journal of Vascular Surgery
    |January 1, 1984

    Summary

    Combining valve replacement with coronary artery bypass grafting (CABG) is controversial. This study found that CABG with aortic valve replacement had lower mortality when cardioplegia was used, while mitral valve replacement with CABG had higher risks.

    Area of Science:

    • Cardiovascular Surgery
    • Cardiac Valve Surgery
    • Coronary Artery Bypass Grafting

    Background:

    • The combination of valve replacement and coronary artery bypass grafting (CABG) for patients with significant concomitant disease is a subject of ongoing debate.
    • Understanding the operative outcomes of these combined procedures is crucial for surgical decision-making.

    Purpose of the Study:

    • To evaluate the operative results and mortality rates of patients undergoing combined valve replacement and CABG.
    • To compare outcomes based on the type of valve replaced (aortic, mitral, or both) and the use of cardioplegia.

    Main Methods:

    • A consecutive series of 201 patients undergoing combined valve replacement and CABG between July 1977 and June 1982 were retrospectively analyzed.
    • Data collected included patient demographics, type of valve procedure, presence of coronary artery disease, use of cardioplegia, and operative outcomes (mortality).

    Main Results:

    • The operative mortality for aortic valve replacement and CABG was 8.5% overall, significantly lower when cardioplegia was used (4.9%) compared to when it was not (20%).
    • The operative mortality for mitral valve replacement and CABG was higher at 21.9%, with specific challenges noted in patients with rheumatic disease or ischemic mitral regurgitation.
    • Late survival rates for aortic valve replacement alone and combined with CABG were similar.

    Conclusions:

    • The use of cardioplegia significantly reduces operative mortality in patients undergoing aortic valve replacement and CABG.
    • Mitral valve replacement combined with CABG carries a higher operative risk, particularly in specific patient subgroups.
    • Combined valve and CABG procedures require careful patient selection and surgical technique to optimize outcomes.
