A case of a giant pulmonary artery aneurysm due to an atrial septal defect with left main coronary artery occlusion.

Cases of coronary artery occlusion due to the exclusion of pulmonary artery aneurysm are extremely rare, and there are few reports of surgical treatment. A 60-year-old woman with pulmonary hypertension due to an atrial septal defect and obstruction of the left main coronary trunk due to the exclusion of a giant pulmonary artery aneurysm underwent surgery. The surgery included atrial septal defect closure, tricuspid annulus plasty, pulmonary artery aneurysmorrhaphy, and coronary artery bypass grafting. One and a half years after the surgery, no re-expansion of the pulmonary artery was observed, and the symptoms of heart failure had improved. There are no reports of improvement in pulmonary valve regurgitation by aneurysmorrhaphy in pulmonary artery aneurysm. Surgery for pulmonary artery aneurysm with the exclusion of other organs was effective, and aneurysmorrhaphy for pulmonary artery aneurysm was acceptable.
