Prevalence of significant congenital heart defects in children of parents with Fallot's tetralogy

Abstract

There is a paucity of empiric recurrence risk data for children of patients with some forms of congenital heart defects, especially cyanotic forms such as Fallot's tetralogy (TF). This information is necessary for accurate genetic counseling because many of these patients now reach reproductive age and wish to know the risk to their children. This investigation estimates the prevalence of significant congenital heart defects (i.e., those brought to the attention of a medical provider) in children of parents with TF.
