Thromboembolic complications (TCs) are important causes of morbidity and mortality after
pediatric cardiac surgery, resulting in longer hospital stay, increased risk of early and
late post-surgical complications, early reoperation, neurologic and organ damage, and
potentially death. The true incidence of blood clots in pediatric surgical patients is
The overarching objective of this study is to further our understanding of TCs, including
quantification, characterization and risk stratification. This study will ultimately allow
the development of effective tools for prevention and early identification of TCs, rather
than focusing on treatment alone.
