A retrospective cohort study on the intraoperative monitoring of right ventricular function in tumors involving the inferior Vena Cava.

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
backgroundThis study aimed to evaluate right ventricular function during surgery for tumor thrombus in the inferior vena cava (IVC) and/or right atrium (RA) using intraoperative transesophageal echocardiography (TEE). It also sought to provide evidence supporting the monitoring and hemodynamic management of the right heart by examining the relationship between the use of vasoactive drugs and changes in right ventricular function in patients with RA invasion versus those with thrombus limited to the IVC after tumor resection.
methodsA retrospective analysis was conducted on patients who underwent IVC tumor resection at Peking University People's Hospital between June 201 3and October 2021. The collected data included patient demographics, right ventricular function parameters (measured by intraoperative TEE), perioperative use of vasoactive drugs, and postoperative hemodynamics. Patients were categorized into two groups: RA (tumor invading the right atrium) and IVC (tumor confined to the IVC).
resultsThe study included 15 patients, 11 of whom (73.3%) had RA invasion. Both fractional area change (FAC) and tricuspid annular plane systolic excursion (TAPSE) showed significant improvement postoperatively. The postoperative right ventricular end-diastolic volume (RVEDV) was larger in the RA group, who also experienced longer hospital stays.
conclusionsPostoperative right ventricular systolic function improved in patients with IVC thrombus. However, RA invasion was associated with longer recovery times, underscoring the need for targeted management to prevent right ventricular failure, particularly following relief of IVC obstruction.
