“…These histological observations, according to the levels of cuttings performed in the cavoatrial junction (CAJ) allowed us to locate the black African sinus node in the atrial wall, under the epicardium, limited outside by the epicardium and inside by the endocardium in a roughly rhombic portion of the right atrium located in the cavoatrial junction. These observations were similar to those described by R E B Hudson [13] in 1967 in England; Kenneth [10] in 1979 in New Zealand, Damián Sánchez-Quintana [14], in 2015 in Spain and Anderson [15], in 2003 in England.…”

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.

“…Therefore, we cannot conclude that A-V conduction tissue was not located in this latter area. Thus, another interpretation of the data in these three cases is that the proximal portion of the A-V cona 1 4.39 duction svstem lies in the location described by Anderson et al,l5 16 but the specialized A-V conduction svstem provides a branch which courses between the ventricular septal defect and the pulmonary outflow tract. A clear answer to this question might have been provided if meaningful evaluation of conduction intervals within the A-V conduction system were possible in this study.…”

“…However, in two of our patients with corrected transposition of the great vessels (cases 1 and 2), and in our case of single ventricle (case 4), the A-V conduction system in the ventricles was delineated posterior to the pulmonary outflow tract between it and the ventricular septal defect, as well as along the anterolateral margin of the ventricular septal defect (figs. 3,4,6). This location between the pulmonary outflow tract and the ventricular septal defect of what appears to be the proximal A-V conduction system differs from the description of Anderson.…”

“…[1][2][3][4][5][6][7][8][9] Histological studies by Anderson et al"5 16 in patients with corrected transposition of the great vessels demonstrated that the A-V conduction system emanated from an A-V node located quite anterior in the A-V junction. These authors also found that the specialized A-V conduction system always coursed on the anterior border of the pulmonary outflow tract and then coursed around the anterolateral margin of the ventricular septal defect, if one were present, in a manner similar to that which we found in case 3 ( fig.…”

SUMMARYThe specialized atrioventricular (A-V) conduction system was electrophysiologically delineated during open-heart surgery in four patients with congenitally corrected transposition of the great vessels and associated ventricular septal defect and one patient with single ventricle. Two consistent observations were made: 1) In no case was the specialized A-V conduction system found in the right atrium, whether or not there was a coronary sinus ostium present. 2) Specialized A-V conduction system electrograms were never delineated posterior to the ventricular septal defect, in contradistinction to this usual location in hearts having ventricular septal defects associated with other congenital lesions. In three of five patients, the initial course of the A-V conduction system of the ventricles was delineated between the anterior aspect of the ventricular septal defect and the pulmonary artery. In one patient the proximal portion of the A-V conduction system was delineated on the anterior aspect of the pulmonary conus. The course and extent of the A-V conduction system delineated in the morphological left ventricle suggests it is a left bundle branch. The surgical implications of the ectopic location of the A-V conduction system anterior to the ventricular septal defect, and the variability of the more proximal portion of the A-V conduction system are discussed.

Lymph drainage of sinu-atrial node in man and dog

The lymphatic vessels of the sinu-atrial (SA) node were investigated after injection of Indian ink plus gelatine in 62 canine and 31 human hearts, the latter of subjects aged between 21 and 80. Lymph was found to be chiefly drained from the SA node of the dog by a vessel which collected lymph near the left margin of the SA node and ran between the superior vena cava and the right circumference of the aorta into the left cardiac lymph collector and through it into the left cardiac node. Approximately in two thirds of cases this main lymph drainage was supplemented by smaller lymphatic branches running into the right tracheo-bronchial nodes. In man, the main route of lymph drainage from the SA node is represented by one or two vessels which run to the right and upwards along the superior vena cava into the inferior tracheo-bronchial nodes (of the bifurcation), lying near the right bronchus. Little branches draining lymph into the cardiac collector are found rarely. It has become evident from histological sections that the lymphatic vessels run between the cells of the conduction system and the collagenous fibres of connective tissue and are not numerous.
