In the blood supply of the heart, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. [1] [2] It travels down the right coronary sulcus, towards the crux of the heart.
The right coronary artery (RCA) is one of two main coronary vessels that supply the myocardium (the other being the left coronary artery). It originates from the right aortic sinus of the ascending aorta and runs in the right part of atrioventricular groove (coronary sulcus) wrapping around the right side of the heart.
Right coronary artery (RCA). The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm.
The right coronary artery specifically provides blood to the right atrium, heart ventricles, and the cells in the right atrial wall, which are called the sinoatrial node. Injuries to...
This article will explain how the right coronary artery works and provide information about its main branches. It will also discuss the health conditions that might affect the right...
Right coronary artery (RCA): The RCA supplies blood to your right atrium and right ventricle (where deoxygenated blood goes before heading to the lungs). Its branches supply the sinoatrial (SA) and atrioventricular (AV) nodes.
The right coronary artery (RCA) arises from the right aortic sinus, which is located just above the right cusp of the aortic valve. It begins as a short trunk from the ascending aorta and proceeds to descend along the right atrioventricular (AV) groove, also known as the coronary sulcus, which separates the right atrium and the right ventricle.
Coronary artery disease, also called CAD, is a condition that affects your heart. It is the most common heart disease in the United States. CAD happens when coronary arteries struggle to supply the heart with enough blood, oxygen and nutrients.
The right coronary artery emerges from the aorta into the AV groove. It descends through the groove, then curves posteriorly, and makes a bend at the crux of the heart and continues downward in the posterior interventricular sulcus.
The right coronary artery finds its origin from the aorta immediately above the right (coronary) semilunar cusp of the aortic valve. It follows a course between the pulmonary trunk and right atrium in the right atrioventricular groove and curves around the acute angle of the heart.
