Course and Distribution of the Right Coronary Artery
The right coronary artery (RCA) originates from the right aortic sinus of the ascending aorta and follows a specific course that supplies critical cardiac structures...
Origin of the Right Coronary Artery
The RCA arises from the right coronary cusp of the aortic valve and immediately enters the coronary sulcus...
Course of the Right Coronary Artery
The RCA travels along the atrioventricular groove and gives off several important branches...
Branches of the Right Coronary Artery
- Right marginal artery: Supplies the right ventricular wall.
- Posterior descending artery: Perfuses the posterior interventricular septum.
- Sinoatrial nodal artery: Provides blood supply to the SA node.
Clinical Significance
Blockage of the RCA can lead to significant myocardial ischemia, particularly affecting the right ventricle and posterior left ventricle...
