Abstract

Rupture of sinus of Valsalva aneurysm (SVA) is a fatal complication, and early detection and immediate surgical correction is critical for lifesaving. However, achieving its definite diagnosis is challenging. Computed tomography (CT) can provide excellent diagnostic value for SVA rupture and other combined anomalies with better spatial resolution of cardiac structure. Herein, we described a case of a young woman with ruptured SVA. SVA rupture was suggested by transthoracic echocardiography and confirmed by cardiac CT. CT scan confirmed SVA rupture by revealing a ring-like structure originating from the right coronary sinus of the aortic valve protruding to the right ventricle with extravasation of the radiocontrast agent. This finding was not clearly defined by transthoracic echocardiography. Cardiac CT may be useful for the diagnosis of ruptured SVA by providing more detailed visualization of adjacent structures and additional information on combined cardiac pathology.
