ANEURYSM OF THE LEFT SINUS OF VALSALVA DRAINING INTO THE RIGHT ATRIUM

The Authors report the case of an arteriovenous fistula connecting the aorta to the right atrium, due to a ruptured aneurysm of the left sinus of Valsalva. Clinical, echocardiographic, and angiographic aspects of this unusual lesion are discussed and correlated. Emphasis is put on the diagnostic value of the echocardiogram; a characteristic dense echo parallel to the posterior aortic wall is seen, along with signs of right ventricular volume overload. Combined with the case history and auscultatory finding (a continuous murmur on the right sternal edge), this may lead to the correct diagnosis by noninvasive means.
