Case Presentation. A 35-year-old female presented with a 6-month history of dizziness, palpitations and sweating. A continuous precordial murmur was audible. Transthoracic echocardiography (TTE) showed abnormal flow between the aortic root and the right atrium (RA) with significant aortic regurgitation. Aortography and transesophageal echocardiography (TEE) confirmed the presence of a ruptured non-coronary sinus of Valsalva aneurysm (SVA) with a fistula to the right atrium. The findings were confirmed during a successful surgical repair which included aortic valve replacement (Figure 1).
Discussion. The non-coronary sinus is involved in less than 15% of patients with congenital SVA. Congenital SVA is often unrecognized until it ruptures, usually in the third or fourth decade, causing acute chest pain, syncope or cardiac failure.1 When a non-coronary sinus aneurysm ruptures, it forms a fistula to the RA in 10% of patients. Cardiac catheterization and aortography, magnetic resonance imaging, 2-dimensional TTE and multiplane TEE are all useful in providing anatomical information to aid transcatheter or surgical management.2
