The vascular anastomoses of the human heart.

Several types of vascular anastomoses were found in the normal human heart which mainly represent the increase in calibre of pre-existing channels in response to certain stimuli such as total or partial occlusion of the coronary arteries, generalized hypoxia, anaemia, bodily exercise, drugs, etc.. The heart circulation though looking rather simple with several types of vessels with different going in and out orifices, is in fact, extremely complex. We could show with this new technique different kind of anastomoses in normal hearts, between the same type of vessels, between vessels and heart chambers and between different types of vessels.
