Pseudoaneurysm of the left ventricular outflow tract following prosthetic valve endocarditis. a Three-chamber view during diastole demonstrates an open St. Jude's valve in the mitral position and a closed St. Jude's valve in the aortic position. A pocket of contrast just anterior to the aortic prosthesis (arrowheads) represents a pseudoaneurysm of the left ventricular outflow tract. b Axial image during systole demonstrates an open aortic prosthesis in short axis. The pseudoaneurysm is visualized to extend as a tubular structure into the aorto-pulmonary window (arrowheads)
