The heart, just like other organs, consists of cells and needs oxygenation / blood supply. Although all four chambers of the heart are filled with blood, the heart receives its nourishment not from the blood within itself; It is fed by the right and left heart arteries (coronary arteries) branching off from the aorta. Initially, it consists of 2 main branches:
Right coronary artery (right coronary artery or RCA for short)
Left main coronary artery. The left main coronary artery divides into 2 after a short segment:
1. left anterior descending artery (left anterior descending or LAD for short),
2nd circumflex artery (circumflex artery or simply Cx).
Therefore, his heart 2 is on the left. It feeds 3 arteries, one on the right.
The right coronary artery bleeds the back side of the heart and the right ventricle. From himself; Branches arise from the acute margin, left ventricle, and sinus node artery. Sometimes it also gives off the posterior descending branch. Cx artery, on the other hand, winds between the atrium (atrium) and the ventricles (ventricle) and directs to the back of the heart. They bleed the side and back. The side branches arising from it are called obtus. Sometimes it also gives off the posterior descending branch.
LADextends from top to bottom on the front surface of the heart. It bleeds the front side of the heart. The branches arising from it are called diagonal and septal branches. It is the vessel that irrigates the largest part of the heart muscle, therefore it is the most important vessel of the heart. Cardiac muscle damage is greater in myocardial infarctions due to this vessel.
- Right coronary artery feeds the right atrium and ventricle and the posterior part of the compartment between the two ventricles.
- Circumflex artery, left It supplies the atrium and the lateral and posterior parts of the left ventricle.
- The left anterior descending artery supplies the anterior aspect of the left ventricle and the anterior part of the compartment between the two ventricles.
These vessels. When it is blocked (myocardial infarction or heart attack), damage and related contraction disorders occur in the heart areas they supply.
It is extremely important that these vessels feeding the heart remain open. In the disease we call atherosclerosis (Coronary artery disease), these vessels Structures called plaques are formed and these can progress over time and cause stenosis and blockages, disrupting the nutrition of the heart muscle and thus causing serious problems.
