Hemodynamics derived from Transesophageal Echocardiography (TEE) - 05/09/11
Résumé |
During a transesophageal echocardiographic (TEE) examination, it is possible to establish the hemodynamic profile.5 Using a combination of information derived from anatomic appearance and Doppler flow, it is possible to identify conditions such as high cardiac output, hypovolemia, elevated left ventricular filling pressure, and elevated pulmonary artery pressure. To achieve this potential, the following variables must be imaged carefully, recorded, measured, and analyzed:
• | Image the chambers, interatrial septum, and great veins |
• | Doppler imaging of pulmonary veins, pulmonary artery, mitral inflow, tricuspid regurgitation, mitral regurgitation jets, and hepatic and great veins |
When applied to TEE this approach is useful for the qualitative identification of abnormalities of cardiac output, filling pressure, and contractility but less so for the exact quantitation of these parameters. For example, the distinction between normal and elevated left ventricular filling pressure, but not precise measurements, can be made.
