“…The difference in the frequency of third coronary artery between the sexes was statistically insignificant. In all the specimens, the ostium of the third coronary artery was to the left and superior to ostium of right coronary artery [10] . Kaur D et al found that out of 77 heart specimens minute accessory coronary ostia for third coronary artery was observed in anterior aortic sinus in 12 specimens (15%) [11] The frequency of the Third Coronary artery in various studies is compared in the The frequency of the third coronary artery noted in our study is comparable to the values noted in the previous studies on cadavers [5,6,7,8] .…”

Introduction:The human heart is vascularised by the Third coronary artery apart from the right and the left coronary arteries. The first branch of the right coronary artery is the conus artery. This branch may arise separately from the anterior aortic sinus in 36% of the individuals which is sometimes termed a 'Third coronary' artery (TCA). Objective: To detect prevalence of Third coronary artery among cadaveric human hearts. Material & Method: After an ethical approval, 50 formalin fixed human cadaveric hearts were collected from Department of Anatomy as well as from mortuary of SGMH Rewa MP. India and a study was done on the origin of third coronary artery in human cadavers by dissection method. Result: Present study find that among 50 cadeveric human hearts 16 hearts having Third coronary artery i.e 32% taking as a separate opening from anterior Aortic sinus. Conclusion: Sound knowledge on third coronary artery is essential to understand the advances made in coronary artery bypass surgeries and newer methods of myocardial revascularisation. Well developed collateral circulation through TCA may allow diagnostic and therapeutic interventions in patients with coronary artery disease.

“…Wherever in anterior sinuses accessory ostia were present, the main ostium was found to be shifted near the commissure. The However, the presence of multiple openings within AAS was explained as a result of the absorption of the bulbous cordis into both ventricles during the heart folding by Stankovic and Jesic (2004).…”

Coronary arteries take origin from the sinus of Valsalva present at the aortic root bounded by a circumferential ridge called sinotubular junction (STJ). Developmentally, the location and morphology of these ostia may vary, and can cause variations in origin of coronary arteries and further complications in any interventional cardiac procedure. This has made it necessary to find the variation in number and location of ostia, their size, shape and relation with surrounding structures. The present study included 40 formalin-fixed cadaveric hearts. The average diameter of the right coronary ostium (RCO) was 3.1 mm and the left coronary ostium (LCO) was 4.2 mm. With regard to the shape of the ostium, the RCO was described as circular in 92.5% (37/40), horizontally elliptical in 7.5% (3/40) of cases. The LCO was circular in 90% (36/40), horizontally elliptical in 5% (2/40) of cases. The RCO was located below STJ in 65% cases (26/40), at STJ in 22.5% (9/40) and above STJ in 22.5% (9/40) cases. LCO were below STJ in 50% (20/40), at STJ in 27.5% (11/40) and above STJ in 22.5% (9/40) cases. Multiple ostia in single aortic sinus were recorded in 24.4 % of cases. The study of the location, shape and morphometry of coronary ostia is essential for any cardiac interventional procedures done for diagnostic and therapeutic evaluation

“…The frequency of the TCA varies depending on the method used for its detection and ranges from 8% and 12% (16,18) on selective coronary angiograms, 17%, 22%, and 29.7% (31)(32)(33) on CT coronary angiograms, and 34.8%, 36.8%, and even 68% on dissection preparations of human hearts (26,34,35).…”

“…For the correct performance of selective angiography of the TCA, it is very important to know the size of the orifice of the TCA in the right aortic sinus, as well as its position relative to ostia of the RCA and sinotubular junction (10,26,27), which was the aim of this research. Furthermore, our goal was to determine the size of the angle between the aorta and the TCA, since this information could prevent its damage during ventriculotomy and other heart surgeries (26,28).…”

Introduction: The human heart is in most cases vascularized by two coronary arteries, the right coronary artery (RCA) and the left coronary artery. The supernumerary coronary artery, which arises independently from the right aortic sinus and passes through sub-epicardial adipose tissue of the pulmonary conus and anterior side of the right ventricle is called the third coronary artery (TCA). Methods: This study consisted of 28 formalin-fixed adult human cadaveric hearts. The presence of the TCA was determined. The position of the orifice of the right and excess arteries in relation to the sinotubular junction was determined, and then also the position of the orifice of the excess arteries “on the o’clock level” in relation to the orifice of the RCA. The radius of these orifices and their distance from the orifice of the RCA were measured. The angle between the aorta and TCA, as well as RCA and conus branch, was measured. Results: A total 11 of specimens had supernumerary arteries. A supernumerary artery was found in two hearts. The angle formed by the aorta with the TCA was 60.09 ± 17.57, while the angle between the aorta and the conus branch had an average value of 89.88 ± 15.92. The orifices of all supernumerary arteries were located below the level of the sinotubular junction. The average diameter of the TCA was 1.49 mm ± 0.41. The average distance between the TCA orifice and the RCA orifice was 2.21 mm ± 1.03. In 45.45% cases, the orifice of TCA was located at the 10 o’clock level. Conclusion: The present study highlights the presence of the TCA. It may constitute a significant collateral circulation contributing to apical and septal perfusion. Interpretation of signs and symptoms of coronary occlusion should therefore include possible contribution of this vascular channel.
