Use of linear and convex ultrasound transducers for evaluation of retrosternal area in patients after cardiac surgery.

The use of linear and convex transducers is usually reserved for ultrasound imaging of vessels, abdominal organs, and lungs. However, the use of these transducers may be extended for the evaluation of thoracic structures. We describe our experience with the use of linear and convex transducers in the evaluation of the retrosternal area, which is usually difficult to visualize by conventional echocardiography and so could provide improved diagnostic information in patients after cardiac surgery.
