(A) The collapse point of the internal jugular vein was localized by ultrasound (white arrow) in an upright position and was marked on the skin. (B) At the end of catheterization, the level of the pulmonary arteries (PAs) was located by fluoroscopy and was also marked on the skin (grey arrow). (C) The craniocaudal distance between the collapse point of the internal jugular vein and the level of the PAs was measured and used for the estimation of PAP. (D) Estimated non-invasive pulmonary artery pressure (ePAP, open circles) and invasive measurements (iPAP, grey circles) of each participant. Note that ePAP and iPAP did not differ > 2 mmHg during the last 10 measurements. (E) Bland–Altman plot depicting agreement between ePAP and iPAP. The central red dotted line represents the mean difference (0.67 mmHg) between the iPAP and ePAP measurements while the green dotted lines represent the standard deviation. There was only one outlier (Subject No. 5).
