Despite being one of the most prevalent cardiac arrhythmias, the cause of atrial fibrillation (AF) in a vast majority of patients remains unknown. There is growing evidence of associated AF in patients diagnosed with coronary arteriovenous fistula. In this discussion, we have included an example of a patient who presented with new-onset AF and was subsequently diagnosed with an anomalous fistula between the right coronary artery and the superior vena cava. Definitive treatment of the fistula resulted in permanent resolution of the AF. Based on this case and a similar case reported in the literature, it is proposed that further research will unmask this possibly underdiagnosed and very treatable cause of AF.
尽管心房颤动（AF）是最常见的心律失常之一，但绝大多数患者的房颤病因仍不明确。越来越多的证据表明，被诊断为冠状动脉瘘的患者会出现相关房颤。在本次讨论中，我们纳入了一名新发房颤患者的病例，该患者随后被诊断为右冠状动脉与上腔静脉之间存在异常瘘管。瘘管的确定性治疗使房颤得到了永久性缓解。基于该病例及文献中报道的类似病例，有人提出进一步的研究将揭示这种可能未被充分诊断且极易治疗的房颤病因。
