Assessment of Right Ventricle Function in Patients with Mitral Repair: Case Series.
Article in Annals of cardiac anaesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesWe aim to assess right ventricular function in patients undergoing mitral valve repair using trans-esophageal echocardiography, focusing on the predictive value of right ventricular longitudinal strain compared to other echocardiographic measures.
designRetrospective analysis.
settingToronto General Hospital.
participantsThirty elective patients undergoing mitral valve repair.
interventionsQuantitative assessment of right ventricular function using transesophageal echocardiography images pre- and post-mitral valve repair, including right ventricular longitudinal strain, fractional area change, tricuspid annular plane systolic excursion, and systolic peak velocity (S'). MEASUREMENTS AND MAIN
results3 patterns of RV strain were identified with right ventricular longitudinal strain emerging as the most significant discriminator among right ventricular functional subgroups, with 43% of cases showing worsening, 20% showing no change, and 37% showing improvement. No correlation was found between right ventricular performance parameters and the need for vasopressors post-cardiopulmonary bypass. There was also no association between initial right ventricular longitudinal strain and difficulty in weaning off bypass or increased demand for pressors. Changes in tricuspid annular plane systolic excursion across all cases warrant further investigation with a larger cohort.
conclusionsRight ventricular longitudinal strain is a valuable tool for assessing right ventricular function post-mitral valve repair, offering insights into immediate postoperative outcomes and long-term right ventricular remodeling. Despite limitations like single-surgeon experience and institution-specific choice of pressors, our study provides useful insights into right ventricular function post-mitral repair surgery, paving the way for future research in larger patient populations.
