The Anatomical Study of Third Coronary Artery in Cadaveric Human Heart

Dr. Ranjana Agrawal

Abstract :

 The Third Coronary Artery (TCA) is a direct anch originates from the Right Aortic Sinus (RAS) without any apparent common trunk with the Right Coronary Artery (RCA). It supplies the infundibulum of the Right Ventricle (RV) which is usually supplied by the conal anches of both the RCA and the Left Anterior Descending (LAD). Distribution of this artery may be important in various diagnostics and surgical procedures related to coronary heart diseases. According to literature the direct connection of Third Coronary Artery with aorta enhances its value as an effective pathway of collateral blood supply. This study was planned with keeping above facts in mind. Study was done on 50 cadaveric heart specimens obtained from department of Anatomy, Netaji Subhash Chandra Bose Medical College Jabalpur (M.P.). Coronary Arteries were traced by underwater micro–dissection and incidences of Third Coronary Arteries were noted. In the study, in 18% specimens the Right Conus Artery arose directly from the anterior aortic sinus (Third Coronary Artery).
