Transesophageal echocardiography (TEE) plays an important role in intraoperative monitoring and can be used to estimate pulmonary artery pressures. An excellent correlation between right ventricular systolic pressure (RVSP) measured by right heart catheterization (RHC) and simultaneously estimated by transthoracic echocardiography is reported and also implemented into the current guidelines for the echocardiographic assessment of the right heart in adults by the American Society of Echocardiography. So far there are no studies evaluating RVSP measured by transesophageal echocardiography (TEE) and recommendations are unclear which transesophageal view is the best for calculation.
