Interventricular Artery

Diagram of the arterial system of the human heart, with the Interventricular Artery highlighted.

The Interventricular Artery, also known as the Anterior Interventricular Artery or Left Anterior Descending Artery (LAD), is one of the main arteries supplying blood to the heart. It is a branch of the Left Coronary Artery and runs down the anterior interventricular sulcus of the heart.

Structure

The Interventricular Artery originates from the Left Coronary Artery, which itself arises from the Aorta. It descends along the anterior interventricular sulcus, a groove that separates the Left Ventricle and Right Ventricle of the heart. Along its course, it gives off several branches that supply blood to the ventricles and the Interventricular Septum.

Function

The primary function of the Interventricular Artery is to supply oxygenated blood to the front part of the Myocardium, the muscular tissue of the heart. This includes the anterior wall of the left ventricle and the anterior two-thirds of the interventricular septum.

Clinical Significance

Blockage of the Interventricular Artery, often due to Coronary Artery Disease, can lead to a type of heart attack known as an anterior wall myocardial infarction. This is a serious condition that requires immediate medical attention.
