title: Echocardiographic features of an unruptured aneurysm of the right sinus of Valsalva.
abstract: A 2-cm aneurysm of the right sinus of Valsalva was documented in a patient with a prosthetic aortic valve. The M-mode findings differed from prior reports and mimicked those of aortic root dissection or a catheter placed in the right ventricular outflow tract. Two-dimensional echocardiograms readily distinguished the aneurysm of the right sinus of Valsalva from the alternative possibilities.
