ABSTRACT
Cardiac disease and thrombosis are intimately related in adults, but primary myocardial
infarction in children is rare. Homozygous familial hyperlipidemia occurs in approximately
1 million children, and causes severe coronary artery disease during childhood. Kawasaki's
disease is an acquired inflammatory disorder, which, if untreated, leads to coronary
artery aneurysms and subsequent myocardial infarction. The current understanding of
the pathophysiology and management of these conditions is discussed. More commonly,
the relationship between cardiac disease in children and thrombosis is that children
being treated for congenital structural cardiac disease develop iatrogenic thrombosis,
most commonly precipitated by central venous access. The epidemiology of common treatment-induced
thrombosis is described, and management guidelines presented. Finally, many cardiac
surgical procedures increase the risk of thrombosis, and prophylactic antithrombotic
therapy is commonly used. The current evidence for prophylaxis in different clinical
situations is presented. Additional study is required in all areas to improve the
outcome for children affected by cardiac disease and thrombosis.
