Introduction. Coronary artery fistulae (CAF) are rare defects with abnormal communication between a coronary artery with either a cardiac chamber or another vascular structure, bypassing the myocardial capillary network. We report a rare multiple arterial coronary fistulae with drainage to the right pulmonary artery. Case Presentation. A 56-year-old male was brought to our hospital for work-up of severe aortic stenosis. Further evaluation revealed multiple CAF with abnormal drainage to the right pulmonary artery. He was discharged after aortic valve replacement and closure of the coronary fistula. Conclusion. This case demonstrates that patients with complex CAF and drainage to the right pulmonary artery can remain asymptomatic and diagnosed accidentally during cardiac imaging, presenting particular challenges in both medical and surgical treatment.
引言。冠状动脉瘘（CAF）是一种罕见的先天性心脏缺陷，冠状动脉与心腔或其他血管结构之间存在异常连通，绕过了心肌毛细血管网络。我们报告一例罕见的多条冠状动脉瘘引流至右肺动脉的病例。病例介绍。一名56岁男性因严重主动脉瓣狭窄入院检查。进一步评估发现多条冠状动脉瘘伴异常引流至右肺动脉。他在接受主动脉瓣置换和冠状动脉瘘闭合术后出院。结论。该病例表明，患有复杂冠状动脉瘘且引流至右肺动脉的患者可能无症状，在心脏成像检查时偶然被诊断出来，这在医学和外科治疗方面都带来了特殊挑战。
