[Normal position and malposition of the heart (author's transl)]

The main types of heart positions and the malpositions are described as demonstrated on plain films of the thorax. Special attention is drawn to the situs ambi -- guous with the poly -- or asplenia which may be recognized from hypoarterial or epiarterial position of the main bronchi and their equal lengths and courses. This diagnosis is important because of the frequent accompanying congenital cardiac malformations and in respect to the planning of angiocardiography.
