    Silent cerebral emboli do not appear to cause long-term intellectual decline after heart surgery. However, open-heart surgery, particularly aortocoronary bypass, can impact cognitive function.

    Area of Science:

    • Neurology
    • Cardiology
    • Neurosurgery

    Background:

    • Cerebral emboli are known complications following heart valve replacement surgery.
    • The potential for clinically silent emboli to impair intellectual function remains a concern.

    Purpose of the Study:

    • To investigate if clinically unnoticeable cerebral emboli affect long-term intellectual function after cardiac surgery.
    • To compare intellectual function changes in patients undergoing valve replacement, aortocoronary bypass, and atrial septal defect closure.

    Main Methods:

    • A cohort of 165 adult patients underwent psychometric testing before and at multiple points after cardiac surgery.
    • Patients were monitored for late cerebral complications like infarction or hemorrhage.
    • Intellectual function was assessed 2 months and 2–8 years postoperatively.

    Main Results:

    • Ten patients experienced late cerebral infarction or hemorrhage, showing impaired intellectual function.
    • Patients with valve prostheses had lower late intellectual function compared to other groups, linked to the operation itself.
    • Aortocoronary bypass patients showed more intellectual function deterioration than other groups.

    Conclusions:

    • The hypothesis that silent cerebral emboli cause late intellectual decline was not confirmed.
    • Intellectual function is significantly influenced by events occurring during open-heart surgery.
    • Further improvements in open-heart surgery techniques are needed to preserve brain function.
