Aorto-atrial fistulas (AAFs) are a relatively rare, but potentially life-threatening condition, where an anomalous connection forms between the aortic structures and the cardiac atria. AAFs are most often the result of an underlying condition concerning the cardiac structures. It may be congenital, secondary to conditions such as aortic dissection, infective endocarditis, or valve replacement, or iatrogenic in nature. Secondary causes incite local deterioration of cardiac wall integrity leading to formation of fistulous connections, whereas iatrogenic causes are more traumatic in nature. Signs and symptoms include those of volume overload and heart failure, with patients often presenting with fever, regurgitative murmurs, cardiac chamber dilation, and pedal edema. The diagnosis of AAFs requires a high degree of clinical suspicion necessitating imaging techniques such as echocardiography, computer tomography, and more invasive procedures. Management is dependent on underlying conditions and include the use of antibiotics, percutaneous closure, and in many cases, open heart surgery. It is important for physicians to be aware of this pathological condition to aid in timely management and favorable outcomes. This review attempts to summarize the various causes and clinical presentations of AAFs over the past decades.

主动脉房瘘：当代回顾。

主动脉房瘘（AAF）是一种相对罕见但可能危及生命的疾病，在这种情况下，主动脉结构与心脏心房之间会形成异常连接。AAF通常是与心脏结构有关的潜在疾病的结果。它可能是先天性的，继发于主动脉夹层，感染性心内膜炎或瓣膜置换等疾病，或者是医源性的。次要原因引起心脏壁完整性的局部恶化，导致瘘管连接的形成，而医源性原因本质上更具创伤性。体征和症状包括体量超负荷和心力衰竭，患者经常出现发烧，反流性杂音，心腔扩张和踏板水肿。AAF的诊断需要高度的临床怀疑，因此需要成像技术，例如超声心动图，计算机断层扫描和更具侵入性的程序。治疗取决于潜在的状况，包括抗生素的使用，经皮封堵以及在许多情况下的开放性心脏手术。对医生而言，重要的是要意识到这种病理状况，以帮助及时进行治疗并取得良好的疗效。这篇综述试图总结过去几十年中AAF的各种原因和临床表现。对医生而言，重要的是要意识到这种病理状况，以帮助及时进行治疗并取得良好的疗效。这篇综述试图总结过去几十年来AAF的各种原因和临床表现。对医生而言，重要的是要意识到这种病理状况，以帮助及时进行治疗并取得良好的疗效。这篇综述试图总结过去几十年来AAF的各种原因和临床表现。
