A sinus of Valsalva aneurysm (SVA) is a rare aortic anomaly. The most common complication is a rupture into the right ventricle and atrium. An SVA rupture into the left ventricle is a rare event. A 42-year-old man visited an outpatient clinic due to worsening exertional dyspnea. A loud to-and-fro heart murmur was detected, and echocardiography revealed a right SVA that had ruptured into the left ventricle, inducing acute heart failure. Computed tomography imaging allowed us to determine that the right SVA had been caused by asymptomatic Takayasu's arteritis. The patient was treated with prednisolone and the right SVA rupture was surgically repaired.
主动脉窦瘤（SVA）是一种罕见的主动脉异常。最常见的并发症是破裂进入右心室和右心房。SVA破裂进入左心室是一种罕见事件。一名42岁男性因劳力性呼吸困难加重就诊于门诊。检测到响亮的来回性心脏杂音，超声心动图显示右SVA已破裂进入左心室，导致急性心力衰竭。计算机断层扫描成像使我们能够确定右SVA是由无症状的高安动脉炎引起的。患者接受了泼尼松龙治疗，并对右SVA破裂进行了手术修复。
