RESUMO

Thirty-one hearts with aortic arch obstruction and patent ductus arteriosus were examined with special reference to associated cardiac anomalies. Six presented with complete interruption of the aortic arch, four with atretic isthmus, twelve with coarctation, and three with tubular hypoplasia. Associated cardiac anomalies were divided into two main groups: (1) septal defect with left-to-right shunt, and (2) left ventricular inflow and/or outflow obstruction. A high incidence (9/19=47.4%) of ventriculo-infundibular malalignment type of ventricular septal defect with subaortic stenosis was observed. Associated cardiac lesions that reduce blood flow in the aortic arch during fetal life may be responsible for poor development of this structure.
