What does LAD stand for in the context of coronary arteries?

• A. Left Anterior Descending artery
• B. Left Atrial Descending
• C. Left Aorta Descending
• D. Left Anterial Descending

Answer: (A)

The acronym LAD refers to the Left Anterior Descending artery, a major branch of the left coronary artery that travels down the front of the heart in the anterior interventricular groove and supplies the anterior wall of the left ventricle and much of the interventricular septum. This vessel is central to myocardial perfusion, so understanding its name helps you connect location, covered territory, and potential clinical impact. Other options aren’t correct because they describe structures that aren’t recognized coronary arteries (for example, a term implying a left atrial or aorta-descending vessel) or are misspelled, so they don’t match the actual anatomy.
