    I'm assuming you mean people who have undergone corrective surgery and may have had a device (say a seal or an occluder) implanted. A clot may form around this device and the risk of breakage of the clot may cause stroke, or a clot into the vessels of the lung (pulmonary embolus). Aspirin thins the blood and helps prevent the formation of such clots. Many people with heart conditions take aspirin for this very same reason.

    Certain surgical repairs, for example, the Fontan repair, can be associated with formation of blood clots in the heart. Aspirin helps prevent clot formation.
