The left circumflex artery courses through which groove?

The left circumflex artery courses through the left atrioventricular groove, which is also known as the coronary sulcus. This groove runs around the heart between the atria and ventricles and is significant for the topographical division of the heart. The left circumflex artery branches off from the left coronary artery and supplies blood mainly to the left atrium and the lateral and posterior walls of the left ventricle.

Understanding the anatomy and course of coronary arteries is crucial for interpreting echocardiograms and identifying areas of myocardial perfusion. The left atrioventricular groove plays an essential role in the heart's blood supply, providing the necessary nutrients and oxygen to the heart muscle. Therefore, recognizing the path of the left circumflex artery through this specific groove is essential for various cardiac assessments and interventions.
