Abnormal position of the cardiac apex to the right associated with reversed position of the liver, stomach, and spleen. Bilobed right and left lungs. Abnormally dilated bronchi of the left hilar region.
The classification of situs does not depend on the position of the cardiac apex. The terms levocardia and dextrocardia indicate only the direction of the cardiac apex. In levocardia, the apex axis points to the left, and in dextrocardia, the axis is to the right. Isolated dextrocardia is referred as situs solitus.
Situs Inversus is therefore classified into situs inversus with levocardia or situs inversus with dextrocardia. Situs inversus with dextrocardia is also called situs inversus totalis because of the reversed direction of the cardiac position, as well as the mirror image appearance of abdominal viscera.
Kartagner syndrome is characterized by situs inversus, bronchiectasis, and sinusitis. It affects 20 % of patient with situs inversus, however, 50% of Kartagner patients have situs inversus.
