The coronary arteries are divided into left and right coronary arteries, of which the left coronary artery can be divided into the left anterior descending branch and the left gyratory branch.
1. Left coronary artery: the left coronary artery originates from the left coronary sinus at the root of the aorta, also known as the left trunk, which is divided into the left anterior descending branch and the left circumflex branch, and sometimes there are also intermediate branches.
Left anterior descending branch: mainly along the interventricular groove down to the apical or around the apical, there are also septal branches, diagonal branches and other branches.
Left echogenic branch: travels backward along the left auricle down to the left atrioventricular groove and divides into obtuse marginal branches.
2. Right coronary artery: it mainly originates from the right coronary sinus at the root of the aorta, descends to the right atrioventricular groove, and continues to the posterior interventricular groove. The right coronary artery can be divided into cone branches, sinus node artery, etc..
Coronary arteries are blood vessels that supply blood to the heart. Coronary artery disease may lead to coronary artery disease, arrhythmia, heart failure and many other heart diseases.
