Estimation of pulmonary artery pressure with transesophageal echocardiography: An observer-blinded test accuracy study.

ABSTRACT:

Abstract

With the declining use of the pulmonary artery catheter (PAC), transesophageal echocardiography (TEE) has become an appealing alternative to obtain pulmonary artery pressure non-invasively using the simplified Bernoulli equation. The validation of this method in the perioperative setting has been scarce with no clear recommendations about which view is the most accurate to estimate right ventricular systolic pressure (RVSP).Therefore, we performed a prospective, observer-blinded, diagnostic test accuracy study to assess the difference in systolic pulmonary artery pressure (sysPAP) measuring both, invasively sysPAP and estimated RVSP with TEE in 3 different views: the mid-esophageal (ME) 4Chamber, the ME right ventricular (RV) inflow-outflow and the ME modified bicaval view
