Absence of one atrioventricular connexion--a terminologic problem.
We present a patient in whom the heart was right-sided, with usual atrial position, absence of the right-sided atrioventricular connexion, and a single outlet via the aorta from a dominant morphologically right ventricle. We use the case to illustrate potential problems in the terminology as used to describe the absence of one atrioventricular connexion. Our case shows why absence of one atrioventricular connexion must be classified according to the side of the missing connexion, and not the anatomy of the atrial or ventricular chambers involved. To simplify the approach to certain hearts, the use of the concept of one concordant or discordant atrioventricular connexion may be justified when the other atrioventricular connexion is absent.
