What is LAD and LCX?
The left anterior descending artery (LAD) supplies the anterior two-thirds of the septum. [2] The LAD is one of two major branches of the LMCA, with the other being the left circumflex (LCx) coronary arteries. Combined, these two supply blood to the left atrium and left ventricle.
