Estimation of Pulmonary Arterial Pressure With Transesophageal Echocardiography: a Pilot Study

NCT03117673 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 39

Last updated 2017-10-20

No results posted yet for this study

Summary

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.

We want to assess if there is a difference in the systolic pulmonary artery pressure measured invasively with a pulmonary artery catheter (PAC) and the calculated right ventricular systolic pressure (RVSP) using transesophageal echocardiography (TEE) in 3 different views: ME 4Ch, ME RV inflow-outflow, ME modified bicaval.
