Diagnostic analysis of abnormal increase of PASP in fetus in middle- and late-stage pregnancy by color Doppler echocardiography.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
objectiveOur study was conducted with an attempt to investigate the diagnostic analysis of abnormal increase of fetal pulmonary artery systolic pressure (PASP) in middle and late pregnancy by color Doppler echocardiography.
methodsFrom August 2017 to January 2019, 52 fetuses with moderate or greater tricuspid high-speed regurgitation were retrospectively analyzed and selected as Group A. 88 fetuses with full-color blood flow of the two ventricles and symmetrical sizes of the cardiac cavities on both sides harboring tricuspid valve and mild regurgitation or a small amount of regurgitation were selected as Group B. The pulmonary artery blood flow acceleration time (AT) and right ventricular ejection time (ET) was measured, and the PASP was calculated.
resultsThe tricuspid regurgitation velocity, tricuspid regurgitation pressure difference and PASP in Group A were higher than those in Group B (
conclusionThe abnormal increase of pulmonary artery can be assessed by color Doppler echocardiography of fetal tricuspid regurgitation, which is worth popularizing and applying in clinic. ADVANCES IN KNOWLEDGE: It was suggested that the middle- and late-stage fetuses with moderate or greater tricuspid regurgitation and with >20 mmHg regurgitation pressure difference should be followed up in clinic. If PASP was ≥70 mmHg with symptoms of right heart failure, fetuses should be closely observed until 35-36 weeks old to ensure fetal safety and early delivery would be recommended.
