  Objective: The purpose of this study was to describe, in 45 normal hearts of black Africans adults, the location of the sinoatrial node. Methods: After naked eye observation of the external epicardial area of the sinus node classically described as cavoatrial junction (CAJ), a histological study of the sinus node area was performed. Results: This study concluded that the sinus node is indistinguishable to the naked eye (97.77% of cases), but still identified histologically at the CAJ in the form of a cluster of nodal cells surrounded by abundant connective tissues. It is distinguished from the Myocardial Tissue. Conclusion: The sinus node is located in the cavoatrial junction but, most often, indistinguishable to the naked eye. Therefore, this area should be avoided during cardiac surgery... View More»
