Abstract:
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.
