Effect of Preoperative Pulmonary Hypertension on the Course of Right Ventricular Function: A Three-dimensional Echocardiographic Study in Valvular Surgery Patients.
Article in Journal of cardiovascular echography. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Context: Postoperative right heart failure is a poor prognostic factor after cardiac surgery. However, the factors that influence perioperative right ventricular (RV) function remain unknown. This study investigated whether preoperative pulmonary hypertension (PH) affects changes in RV systolic function during the perioperative period. Aims: This study aimed to determine the effect of preoperative PH on changes in RV systolic function in patients undergoing aortic or mitral valve surgery. Settings and Design: This was a retrospective review of three-dimensional echocardiographic datasets of 157 patients undergoing aortic or mitral valve surgery. Materials and Methods: Patients were classified into the PH ( Statistical Analysis Used: A mixed-effects model was used to compare changes in RV function between groups. Results: Over 1 year, no significant differences in trends were observed between groups for any of the parameters. However, a significant deterioration in free wall RVLS was observed in the non-PH group when focusing on the change from baseline to 1 year ( Conclusions: In patients undergoing valvular surgery, the presence of preoperative PH did not significantly influence changes in RV function throughout the perioperative period.
