[Diagnosis of right ventricular function by transesophageal echocardiography]

Transesophageal echocardiography allows the complex structure of the right ventricle to be adequately visualized. Image analysis with specially designed software provides qualitative and quantitative information on right ventricular function, whether during surgery or in the intensive care unit, where the technique has proven particularly useful for early diagnosis of right ventricular insufficiency in patients receiving assisted ventilation. Loading conditions and degree of dysfunction of the right ventricle can be monitored in real time under various clinical conditions, significantly facilitation management.
