Echocardiographic Assessment After Pulmonary Thromboendarterectomy for Chronic Thromboembolic Pulmonary Hypertension: Which Parameters Reflect Improved Right Ventricular Function?
Article in Pulmonary circulation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Traditional echocardiographic measures of right ventricular (RV) function, such as tricuspid annular plane systolic excursion (TAPSE) and peak systolic velocity at the tricuspid annulus (S'), may be unreliable after cardiac surgery due to changes in loading conditions and myocardial mechanics. This study aimed to evaluate RV function following pulmonary thromboendarterectomy (PTE) for chronic thromboembolic pulmonary hypertension (CTEPH) and to identify alternative echocardiographic indices that better reflect postoperative RV recovery. This retrospective, single-center study included CTEPH patients who underwent PTE at Cleveland Clinic between January 2020 and March 2021. Echocardiographic evaluations were performed preoperatively and within 3 months postoperatively. Parameters assessed included RV size, function, volumes, pulmonary pressures, and tricuspid regurgitation (TR) severity. TAPSE and RV S' significantly decreased postoperatively (mean changes -0.75 cm and -2.8 cm/s, respectively;
