Right coronary artery
(Redirected from Arteria coronaria dextra)
== Right Coronary Artery ==
The right coronary artery (RCA) is one of the two main coronary arteries that supply blood to the heart. The RCA originates from the right aortic sinus of the ascending aorta and travels down the right atrioventricular groove towards the crux of the heart.
Anatomy[edit | edit source]
The right coronary artery typically gives rise to several important branches, including the right marginal artery and the posterior descending artery (PDA). The RCA supplies blood to the right atrium, right ventricle, the bottom portion of both ventricles, and the back of the septum.
Branches[edit | edit source]
- Right marginal artery: This artery branches off the RCA and supplies the right ventricle.
- Posterior descending artery (PDA): This artery runs along the posterior interventricular sulcus and supplies the posterior third of the interventricular septum.
Function[edit | edit source]
The primary function of the right coronary artery is to supply oxygenated blood to the right side of the heart, which includes the right atrium and right ventricle. It also supplies blood to the sinoatrial (SA) node in about 60% of people, which is crucial for maintaining the heart's rhythm.
Clinical Significance[edit | edit source]
Blockage or narrowing of the right coronary artery can lead to myocardial infarction (heart attack), particularly affecting the right side of the heart. This can result in symptoms such as chest pain, shortness of breath, and fatigue. Treatment may involve coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI).
