The shape of the heart is like an inverted cone with slightly flat front and back. If it is regarded as the head, the coronary artery located at the top of the head and almost around the heart is like a crown, which is the origin of its name. The coronary artery is the artery that supplies blood to the heart. It starts from the aortic root in the aortic sinus and runs on the surface of the heart. According to Schlesinger's classification principle, the distribution of coronary artery was divided into three types: 1. Right dominant type; 2; 2. Balanced type; 3. Left dominant type.
