Abstract
The pathological features of 13 cases with juxtaposition of the atrial appendages in human autopsy cases were studied. The anomaly occurs most frequently in association with transposition of the great vessels, ventricular septal defect, patent foramen ovale and obstructive lesions of the tricuspid and pulmonic valves. The malformation complex of tricuspid atresia, atrial and ventricular septal communication, and the transposition of the great vessels seems particularly common with juxtaposition of the atrial appendage. A recent case showed a small accessory right atrial appendage lying in juxtaposition to the left atrial appendage. A normally situated right atrial appendage was present. Review of the other 12 cases showed normally situated right atrial appendages and well-formed accessory appendages lying in juxtaposition to the left atrial appendages. Juxtaposition of the atrial appendages should apparently be reinterpreted as an accessory appendage or atrial diverticulum.This publication has 1 reference indexed in Scilit:
