Summary

Background: Blood clots cause poor outcomes, including death, in babies with heart defects that require a surgical connection ("shunt") to provide blood flow to their lungs. Aspirin (ASA) blocks the part of the blood that helps clots form (platelets). Aspirin is used in babies with shunts to prevent blood clots. The dose of aspirin given to babies is based on adult research. Because babies are different from adults, the investigators do not know if the dose is enough to block platelets, or if it is too much and may cause bleeding. The investigators can test the platelets using a blood test called Thromboelastography with Platelet Mapping (TEG-PM). This test needs a small amount of blood so it can be used in babies.

Hypothesis and Specific Aims: The investigators suspect the aspirin doses typically given babies are not enough to block platelets and prevent blood clots in their shunts. The investigators want to determine the percentage of babies whose platelets are not blocked enough (\< 70% inhibition), by using TEG-PM. The investigators also want to determine how often bleeding or clots occur in babies receiving aspirin.
