Figure Lengend Snippet: Results of the external validation. ( A–C ) Agreement between the invasively measured pressure curves (i.e. ground truth) and those predicted by the three investigated methods using the invasively derived peak systolic pressure as input. ( D–F ) Agreement between the invasively measured pressure curves (i.e. ground truth) and those predicted by the three investigated methods using the non-invasively derived peak systolic pressure (i.e. the peak RV pressure estimated from the Doppler echocardiography–derived peak velocity of the tricuspid regurgitation jet) as input. The thick red line indicates the mean difference. LV, left ventricular; PVC, pulmonary valve closure; PVO, pulmonary valve opening; RV, right ventricular; TVC, tricuspid valve closure; TVO, tricuspid valve opening.
Article Snippet: Comprehensive 2D and 3D transoesophageal echocardiography was performed during the operation to quantify RV volumes and RVEF (EPIQ CVx system, X8-2t transducer, Philips Healthcare, Best, The Netherlands; and 4D RV-Function 2, TomTec, Unterschleissheim, Germany).
