Misleading supine chest X-ray in complete detachment of a Starr-Edwards prosthetic aortic valve
Abstract:
The authors report a case of total detachment of a Starr-Edwards aortic valve prosthesis occurring eleven years after implantation. The detached valve had embolized into the descending thoracic aorta. The prosthetic valve was projected into an apparently normal position on a supine chest X-ray. The correct diagnosis was thus delayed. The authors stress the importance of obtaining lateral views or performing fluoroscopy and/or echocardiography in the emergency room in patients with acute chest symptoms after heart valve replacement.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
