Transoesophageal echoardiography in cardiac surgery

Project Details

Our research program on transoesophageal echocardiography is investigating the impact of this new technique on diagnosis, management and outcome of patients during cardiac surgery. This research stream was developed by Professor Colin Royse and continues with many collaborators.

The use of ultrasound is the modern day revolution in anaesthesia and acute care medicine. The use of ultrasound in the acute care specialties of anaesthesia, intensive care, emergency medicine, and surgery has evolved from discrete, office-based echocardiographic examinations performed by radiologists or cardiologists to the real- time or point- of- care clinical assessment and interventions by the acute care physician. Use of ultrasound improves speed and accuracy of clinical assessment and is non-invasive and cheap.

Transoesophageal echocardiography is now routinely used by anaesthetists during cardiac surgery and increasingly used in intensive care and in non-cardiac surgery. However its applications are still being discovered, which is expanding in part due to advances in technology, such as the new 3-dimensional machines.
