ResumoTransesophageal 2-D and Doppler echocardiography provide useful information about cardiac structure and function. While global LV systolic function can be quantitated using wall stress cross-sectional area shortening relations, TEE has become an important tool in detecting ischemia related regional wall motion abnormalities in intraoperative patients. Analysis of mitral and pulmonary venous flow velocity patterns provide access to assessment of LV diastolic function and filling pressures. Dynamic changes in cardiac output can be reliably monitored using aortic or pulmonic pulsed Doppler flow velocity signals. Incorporation of continuous wave Doppler promises direct estimation of systolic pulmonary artery pressures by sampling tricuspid regurgitant jets. Transesophageal cardiac imaging has therefore become a powerful tool to gauge hemodynamic variables in patients with heart disease.
