Figure 1

Receiver operating characteristic (ROC) curves of transoesophageal echocardiography (TEE) Doppler parameters to predict an invasive pulmonary artery occlusion pressure (PAOP) ≤ 18 mmHg in protocol A. Left panel: area under the curves (AUC) with standard error and 95% confidence intervals (CI) and p values (comparison of the actual AUC with the 0.50 AUC) of mitral Doppler parameters were as follows: E/A, 0.83 ± 0.09 (95% CI: 0.70–0.92; p = 0.0002); mitral E wave deceleration time, 0.81 ± 0.07 (95% CI: 0.67–0.90; p < 0.0001); atrial filling fraction: 0.82 ± 0.07 (95% CI: 0.68–0.91; p < 0.0001). Right panel: AUC with standard error and 95% CI of pulmonary vein Doppler parameters were the followings: S/D, 0.78 ± 0.07 (95% CI: 0.65–0.88; p = 0.0001); systolic fraction, 0.84 ± 0.06 (95% CI: 0.72–0.93; p < 0.0001). Abbreviations: AFF, atrial filling fraction; DTE, deceleration time of early diastolic mitral E wave; SF, systolic fraction.
