Abstract congenital heart disease is an integral part of many genetic syndromes such as the major trisomies 13, 18, and 21. Little information, however, is available with reference to the incidence of cardiac anomalies in the trisomy 7 syndromes. Two patients with partial trisomy 7q, one of whom had congenital heart disease, are presented. A reviews of the literature reveals incomplete description of the cardiovascular abnormalities in the majority of case reports of patients with this syndrome, however, when described it appears that there are no specific defects associated with trisomy 7p and 7q, but only an increased frequency of occurrence. Further clinical and postmortem data regarding details of the congenital heart defects associated with trisomy 7 is requried to confirm this preliminary observation.
