The Left Coronary Artery (LCA) arises from the superior portion of the of the left aortic sinus just below the sinotubular junction. Typically it begins as a Left Main (LMCA) for about 0 to 10mm before giving rise to the LAD and LCX. In less than 1% there is no LMCA and the LAD and LCX originate directly from the left sinus of valsalva; so-called seperate ostia. The left main can also give rise to intermediate or anterolateral (AL) branches that originate from the left main inbetween the LAD and LCX. | The Left Coronary Artery (LCA) arises from the superior portion of the of the left aortic sinus just below the sinotubular junction.
