[Echocardiographic aspects of the aortopulmonary window. Report of a case with angiocardiographic correlations].

A case of complex congenital heart disease is presented with diagnosis of; ventricular septal defect, interrupt aortic arch, patent ductus arteriosus and aorticopulmonary window. The latter condition was studied by means of M mode and two-dimensional echocardiographic techniques. The heart was scanned perpendicular to its long axis at the origin of the great arteries. This scan revealed an image of two adjacent circular structures which has been previously described as suggestive of dTGA or Double-outlet right ventricle. The clinical picture discarded the possibility of dTGA, and the atrioventricular relationship established by the cross-sectional echocardiography invalidated the diagnosis of Double-outlet right ventricle. The cause of the echocardiographic morphologies observed are discussed.
