GONZALEZ RAMOS, Luis Antonio et al. Left juxtaposition of the heart atrial appendages. Arch. Cardiol. Méx. [online]. 2007, vol.77, n.3, pp.232-236. ISSN 1665-1731.

We present the first case of left juxtaposition of the right atrial appendages that has been seen at the Children's Hospital of the state of Sonora. This anomaly was associated with a complex congenital heart defect, i.e. absence of the right atrioventricular connection and transposition of the great arteries. The two-dimensional echocardiogram is the usual study to reach a clinical diagnoses, but it may also be an incidental of finding during surgery or during autopsy, in ocurred in our case. Its timely diagnosis may have implications in the surgical treatment and in therapeutic cardiac catheterization.
