We describe a case of ruptured sinus of Valsalva aneurysm (RSVA) with moderate aortic regurgitation (AR), which developed on the second day after admission. The AR was caused by a hemodynamic effect solely, in which the shunt blood flow through ruptured site pulled the right aortic cusp away from closure. The pathological mechanism of the AR was clearly visualized by intraoperative transesophageal echocardiography (TEE) and the AR was successfully resolved after simple closure of the RSVA without any additional procedure to the aortic valve.
我们描述了一例伴有中度主动脉瓣反流（AR）的瓦氏窦瘤破裂（RSVA）病例，该病例在入院后第二天出现。AR完全是由血流动力学效应引起的，即通过破裂部位的分流血流将右主动脉瓣叶拉开使其无法闭合。术中经食管超声心动图（TEE）清晰显示了AR的病理机制，在单纯闭合RSVA后，AR成功得到解决，未对主动脉瓣进行任何额外操作。
