Coronary artery anomalies are rare, but still rarer is anomalous branching pattern of the left coronary artery (LCA) alone, without any congenital anomalies. We report the case of a 50-year-old man who presented with dyspnea on exertion New York Heart Association (NYHA) class II, had a positive stress test, and his coronaryangiogram revealed the left main coronary artery (LMCA) dividing into four branches. This type of branching pattern is quite rare. He had type I dual left anterior descending (LAD) artery in addition to a fairly large ramus intermedius (RI) and a nondominant left circumflex (LCx) arising from the LCA. Awareness and recognition of dual LAD is of importance to surgeons and interventionalists alike in planning the revascularization strategy.
