title: A proposed method to visualize the ductus arteriosus on transesophageal echocardiography.
abstract: The ductus arteriosus occupies a uniquely privileged position in the management of heart disease; it initiated not only the surgical management of congenital lesions but also the percutaneous management of this subset. During trans-thoracic echocardiography (TTE) the ductus is often visualized using 'high' parasternal (or the 'ductal' view) or suprasternal windows. It is generally agreed that imaging ductus during transesophageal echo (TEE) can be sub-optimal. During TEE imaging, visualization of the ductus arteriosus is obscured by the acoustic impedance offered by the left main bronchus; adjunct techniques such as insertion of a saline filled balloon in this airway have been used. We describe a simple maneuver that allows visualization of the patent ductus arteriosus during TEE imaging without the use of any adjuncts.
