Transoesophageal Echo

About

  • Transoesophageal echocardiography (TOE) is now a standard technique in clinical practice and is an essential ultrasonographic technique for rapid bedside tomographic evaluation of the cardiovascular system. Imaging from the confines of the gastro-oesophageal track reduces signal attenuation and permits the use of higher ultrasound frequencies, thereby providing an enhanced spatial resolution.

    Transoesophageal echocardiography (TOE) is now a standard technique in clinical practice and is an essential ultrasonographic technique for rapid bedside tomographic evaluation of the cardiovascular system. Imaging from the confines of the gastro-oesophageal track reduces signal attenuation and permits the use of higher ultrasound frequencies, thereby providing an enhanced spatial resolution.

    In patients with atrial fibrillation, clinical and echocardiographic markers of thromboembolism are helpful for risk stratification and include a history of hypertension, a previous thromboembolic event, and heart failure. TOE also plays a role in the interventional laboratory for percutaneous interventions such as transcatheter closure of atrial septal defects and ventricular septal defects.
