Aneurysms of the sinus of Valsalva (ASV) are rare, with an incidence ranging from 0.1% to 3.5% of all congenital cardiac defects and a prevalence of 0.009% in an autopsy series.ASVs occur much more frequently in the right coronary sinus of Valsalva. Previous reports, based on necropsy and cardiac surgery findings, estimated that 20% of ASVs are unruptured. Patients with an unruptured ASV may remain asymptomatic for a long period of time until rupture. They may also presented with dyspnea, palpitation, and angina-like chest pain. Aortic insufficiency in the patients with unruptured ASVs is common, and other valvular lesions can be observed in these patients as well. Echocardiography, as a noninvasive and portable tool, is widely used to detect ASVs. Additionally, computed tomography and cardiac magnetic resonance imaging, alone or in combination, can provide precise information about its anatomic extension and intrinsic characteristics of the pathology.
主动脉窦瘤（ASV）较为罕见，在所有先天性心脏缺陷中，其发病率为0.1%至3.5%，在尸检系列中的患病率为0.009%。ASV在主动脉右冠状动脉窦中更为常见。基于尸检和心脏手术结果的既往报告估计，20%的ASV未破裂。未破裂的ASV患者可能长期无症状，直至破裂。他们也可能出现呼吸困难、心悸和心绞痛样胸痛。未破裂ASV患者中主动脉瓣关闭不全很常见，这些患者也可观察到其他瓣膜病变。超声心动图作为一种无创且便携的工具，被广泛用于检测ASV。此外，计算机断层扫描和心脏磁共振成像单独或联合使用，可提供有关其解剖范围和病变内在特征的精确信息。
