    Combined heart valve and coronary artery bypass graft surgery showed significant improvements in patients. However, early mortality was noted, particularly in aortic valve replacement cases, highlighting the need for careful patient selection and management of coronary lesions.

    Area of Science:

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

    Context:

    • The study examines combined surgical procedures for cardiac valves and coronary arteries.
    • Data was collected from 27 consecutive patients between 1970 and 1976.
    • This period saw advancements in cardiopulmonary bypass techniques and valve replacement procedures.

    Purpose:

    • To evaluate the outcomes of combined valve replacement and coronary artery bypass grafting.
    • To identify risk factors and complications associated with this complex surgical approach.
    • To refine indications for coronary arteriography in patients undergoing valve surgery.

    Summary:

    • The study involved 18 aortic valve replacements, 8 mitral valve replacements, and 1 double mitro-aortic replacement, with a longer cardiopulmonary bypass time compared to valve replacement alone.

  • In-hospital mortality was 18.5%, concentrated in the aortic valve group and earlier cases, with post-mortem findings revealing unaddressed coronary lesions.
  • Despite complications, 17 followed-up patients showed substantial improvement, with a mean follow-up of 24 months.

    • Impact:

    • The findings underscore the importance of addressing both valvular and coronary lesions concurrently.
    • The study suggests expanding indications for coronary arteriography to include most patients undergoing valve surgery, excluding specific age groups or those without atherosclerosis risk factors.
    • Identifying unsuspected coronary lesions as a significant operative risk factor informs future surgical strategies.
