A 52-year old man was referred to our hospital for atrial fibrillation ablation therapy. A multislice computed tomography study demonstrated a giant coronary artery aneurysm situated just proximal to the left anterior descending（LAD), LAD stenosis and coronary-pulmonary artery fistula. The fistula was ligated and the aneurysm was resected under cardiopulmonary bypass. The left internal thoracic artery was used as a bypass graft to the LAD as well as a patch for closure of the LAD orifice to avoid left circumflex artery stenosis. We report a rare case of giant LAD aneurysm with coronary-pulmonary artery fistula.
