“…Halpearn [12] and Meek [16] reported that 3 atrial branches originated from each of the right and left coronary arteries, while Moore [15] reported that 2 branches originated from each coronary artery. According to Pianetto [18], 3 to 5 branches originated from the right coronary artery and 2 to 4 branches originated from the left circumflex artery.…”

“…In the reports published so far, the arterial branch forming the SNA of dogs was either a single atrial branch originating from the right coronary artery [11][12][13][14][15], a single atrial branch originating from the left circumflex artery [16,17], two atrial branches originating from the right coronary artery and left circumflex artery [18], or two atrial branches originating from the right coronary artery [17]. Such discrepancies in the observations concerning the arterial branches forming the SNA may have resulted from the variation in the breed of dog used in each study, and this assumption supported our observation in mongrels.…”

“…Occasionally, however, there have been cases where human SNAs consisted of two atrial branches, one originating from the right coronary artery and the other from the left circumflex artery [24][25][26]. Similarly, various cases of SNAs in dogs have been reported where the SNA consisted of a single atrial branch originating from either the right coronary artery [11][12][13][14][15] or left circumflex artery [16,17]. In other studies on dogs, however, two atrial branches were seen, one originating from the right coronary artery and the other from the left circumflex artery [18].…”

Summary. Postmortem coronary angiography wasperformed in 20 beagles and 15 mongrels, and the origin and distribution of the sinus node arteries (SNAs) were subsequently investigated using soft X-ray radiography, the tissue elearing method, and histological examination. In 19 of 20 beagles, the SNAs consisted of a single atrial branch originating from the right coronary artery, and the distribution pattern of the atrial branch seemed to be uniform. In contrast, the following three different patterns were recognized in the atrial branehes forming the SNAs of mongrels: (1) distribution by two atrial branches, i.e., one originating from the right coronary artery and the other from the left circumflex artery, (2) dual distribution by two atrial branches originating from the right coronary artery, and (3) distribution by a single atrial branch originating from the right coronary artery or from the left circumflex artery. In 26 of the 30 dogs which were histologically examined, the SNAs ran õutside of the sinus node and were not centrally located. In the beagles, the proximal atrial branch from the right coronary artery reached the atrioventricuolar node area and supplied blood to the atrioventricular node together with the arterial branches derived from the anterior septal artery and posterior septal artery. In addition, the arterial branch of the SNAs reached the atrioventricular junction area. These findings should contribute to clinical, pharmacological, and pathological studies of the cardiovascular system, including studies on cardiac arrhythmias in beagles.

Even before the time of Servetus arid Joliii Hunter obserrations were niade on the coi*onaries by a n Arab physician of the 13th Century, Ibii Nafis, dean of the 1Iaiisourp Hospital in Cairo, Egypt. Accordiiig to Haddad aiid Khairallali ('36) he stated that the blood is aerated iii the lungs aiid that tlie heart is iiourislied by its owii vessels. Whitten published a review and aiia1;vsis of the many methods used prior to 1928. As he pointed out, actual dissection of the vessels is tediouh and tlie finer braiiches are frequently destroyed. The cleared preparations do not perinit easy esaniinatioii of the deeper vessels. Iiijectioii followed by plane roentgenography iiivolves cutting along or across branches thereby destroying their relationship and also fails to give depth. The m e of steroscopic x-ray pictures results in overlapping of the branches. Whitten concluded that of the methods reviewed the injection and corrosion methods were the best and recommended celloidin for injecting the vessels. The actual injection requires several days aiid the castiiig of the heart cavities is done by a n additional procedure.Since 1928 the injection-corrosion aiid iiijectioii-roeiitgeiiography methods h a~e been dereloped further. Schlesinger ( '38) used the injection-plane roentgenography method. Hip 43
