Morphometry of coronary sinus and its role in cardiac cannulation
Keywords:
morphometry, coronary sinus, cardiac cannulationAbstract
Introduction:- The coronary sinus is a collection of veins, joined together to form a large vessel that collects blood from the heart muscle (myocardium) 1. Most cardiac veins drain into the wide coronary sinus, 2 or 3 cm long, lying in the posterior atrioventricular groove between the left atrium and ventricle.2 The sinus opens into the right atrium between the opening of the inferior vena cava and the right atrioventricular orifice. An endocardial fold may guard the entrance of sinus valve of the coronary sinus or Thebesian Valve. The fold may be absent or may cover the ostium of the sinus completely or partially. Material & Method:- The present study was conducted in the anatomy department of medical college Baroda, Gujarat. One hundred formalin-fixed hearts specimens were taken for the study The dimensions of the coronary sinus ostium in millimetres was measured with the help of digital vernier calliper. Craniocaudal and transverse length were measured and recorded in Microsoft excel. Result :- In the current study, we observed that 58 hearts had the coronary sinus with a thebesian Valve and the rest 42 were without a thebesian Valve.
