“…2,[11][12][13][14][15][16][17][18] Inadequate TR jet Doppler signal is the most common source of inappropriate PASP DE estimation. Our hypothesis was that the hemodynamic consequences of severe TR on atrioventricular interaction may be a confounding factor for PASP DE measurement as PASP DE estimation relies on pressure difference between RV and RA.…”

“…As previously shown, CVP and SPAP were also associated with mortality, 20 but they are sometimes missing in clinical echocardiography and the values may be erroneous. [21][22][23] There is therefore a need for other parameters to help in risk stratification.…”

“…First, the reference standard for PA pressure used in this study was Doppler echocardiography, which may not equal an invasive method such as right heart catheterization. Moreover, recent studies have questioned the accuracy of Doppler echocardiography in determining PA pressure 12 , 13 . Second, lung sonography is an operator‐dependent method.…”

“…The right ventricular (RV) systolic pressure was estimated by adding the right atrial (RA) pressure to the transtricuspid pressure gradient. 1,[11][12][13] The transtricuspid pressure gradient was calculated from the peak tricuspid regurgitation velocity by using the modified Bernoulli equation. The RA pressure was estimated to be 5, 10, or 15 mm Hg based on the variation in the size of the inferior vena cava 13 : complete collapse, RA pressure = 5 mm Hg; partial collapse, RA pressure =10 mm Hg; and no collapse, RA pressure = 15 mm Hg.…”

ulmonary hypertension is a common and important complication of interstitial lung diseases, which substantially affects the exercise tolerance and survival of patients with these diseases. Right heart catheterization is the reference standard for measurement of pulmonary artery (PA) pressure; however, it is an invasive technique and is not always performed for patients with interstitial lung diseases. Transthoracic echocardiography is a useful technique for noninvasive estimation of PA pressure 1,2 through tricuspid regurgitation or pulmonary valve regurgitation and is readily available anywhere. -Zhi Zheng, PhD, MD, Quan Zheng, MS, Jing Zhou, BS, Bin Yang, PhD, MD Received October 23, 2014, Xiao ORIGINAL RESEARCHObjectives-This study was conducted to evaluate the value of sonographic B-lines (previously called "comet tail artifacts") in assessment of pulmonary hypertension in patients with interstitial lung diseases.Methods-One hundred thirty-four patients with clinically diagnosed interstitial lung diseases complicated by pulmonary hypertension underwent transthoracic lung sonography and Doppler echocardiography for assessment of the presence of B-lines, the distance between them, and the pulmonary artery (PA) systolic pressure. A correlation analysis and a receiver operating characteristic curve analysis were performed.Results-All patients had diffuse bilateral B-lines. The maximum number of B-lines seen in any positive zone (not a summation) was significantly correlated with the severity of PA systolic pressure (r = 0.812; P < .0001), and a linear regression equation could be demonstrated: that is, y = 6.06 x + 17.57, where x and y represent the number of Blines and PA systolic pressure, respectively. A cutoff of more than 4 B-lines seen in any positive zone had 89.5% sensitivity, 85.0% specificity, and 87.2% accuracy in predicting elevated PA pressure (>30 mm Hg).Conclusions-The number of B-lines is useful in assessment of pulmonary hypertension, especially when tricuspid regurgitation and pulmonary valve regurgitation do not exist or cannot be satisfactorily measured by Doppler echocardiography.

Limitations and Strengths of Doppler/Echo Pulmonary Artery Systolic Pressure–Right Heart Catheterization Correlations: A Systematic Literature Review

Abstract: D PASP-RHC correlations were high and between-method differences less in patients with left heart pathology but were poorer for right heart diseases and studies with proportionately more normal PASPs on RHC for which further study is needed.
