The combination of coronary artery aneurysm and pulmonary artery fistula is extremely rare and its common cause is atherosclerosis. A 61-year-old woman presented with a giant coronary artery aneurysm with pulmonary artery fistula and intramyocardial calcifications of the left ventricle associated with progressive atherosclerosis due to chronic hemodialysis. The coronary artery aneurysm was resected under cardiopulmonary bypass because of hemodynamic instability due to restrictive cardiac dysfunction. The patient's restrictive cardiac dysfunction was improved after aneurysm resection. Surgical resection should be considered for giant coronary artery aneurysm with restrictive cardiac dysfunction.
冠状动脉瘤和肺动脉瘘的联合非常罕见，其常见病因是动脉粥样硬化。一名 61 岁女性因慢性血液透析导致进行性动脉粥样硬化而出现巨大冠状动脉瘤合并肺动脉瘘和左心室心肌内钙化，伴有限制性心功能障碍。由于限制型心功能障碍导致心功能不稳定，在体外循环下切除了冠状动脉瘤。动脉瘤切除后，患者的限制型心功能障碍得到改善。对于合并限制型心功能障碍的巨大冠状动脉瘤，应考虑手术切除。
