NeoCardioSim based on an advanced fully animated heart model. Our models was created by used magnetic resonance imaging and expert knowledge form physicians and anatomists.

The Newborn's heart is such a difference as the botalle connecting the pulmonary trunk to the aorta and the opening connecting the right and left atrium. Many neonatal cardiac pathologies result from the problems associated with these elements. The rest elemenst and pathology may be common for adults and newborns.
