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.
