[A case of thoracopagus with an unusual cardiac anomaly]

A case of Siamese twins is described being especially interesting because of the rare kind of heart malformation. The joint heart shows in particular a reduction of the heart rooms, a defect of the ventricular septum and a transposition of the big vessels in one of the individuals. Moreover a multilobularity of the lungs, a fusion liver and a partly joint portion of the small intestine is to be seen.
