Clinical importance of intramural blood vessels in the sino-atrial segment of the conducting system of the heart

Abstract: We studied the morphology and histology of intramural vessels in the sino-atrial [S-A] segment of the cardiac conducting system because of the clinical relevance of the anatomy of the microvascular system for those performing cardiac surgery or coronary angiography, catheterization or arterialization. In 25 human and 25 canine hearts the vasculature was fixed by the Komahidze method, the anatomy was studied and sections were stained and studied by microscopy. Of clinical importance is a finding of considerable… Show more

“…In our study we were not able to identify vasculature within the sinoatrial node region, which is in contrast to previous reports that the sinoatrial node has a rich intramural network of anastomosing blood vessels and that the density of the microvasculature in the node is greater than in adjacent atrial tissue (Ovcina and Cemerlic, 1997). A possible explanation is the focal depth of the applied probe (approximately 26 μm).…”
