[Dissection of the heart: a useful guide to understanding the three-dimensional gross anatomy].

In order to understand the three-dimensional gross anatomy of the heart, it is important to observe the inner structures of the chambers and the spatial relation between the valves and the ventricles. In our dissecting laboratory, we designed a guide to dissection of the heart according to the following procedures. First, we observe the surface anatomy of the heart in the pericardial cavity, remove the heart and then identify the coronary vessels, open the four chambers and observe the intra-cardiac structures.
