Right ventricle to pulmonary artery coupling as a predictor of perioperative outcome in patients with secondary mitral valve insufficiency.
Article in Cardiology journal, 2024. 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
backgroundThe aim of the study was to assess some parameters of right ventricle (RV) function as predictors of short-term mortality in patients with severe secondary mitral regurgitation (SMR) after mitral valve surgery.
methodsWe conducted a retrospective analysis of 112 consecutive patients with severe SMR who had undergone mitral valve repair or replacement with or without concomitant coronary artery bypass surgery. We assessed RV to pulmonary artery coupling by calculating the ratio of tricuspid annular plane systolic excursion (TAPSE) to non-invasively estimated RV systolic pressure (RVSP). The study endpoint was 30 days post-procedural mortality.
resultsOverall, the 30-day mortality was 6%. TAPSE/RVSP ratio < 0.42 mm/mmHg was a significant predictor of mortality and remained so after adjusting for age and sex. The Kaplan-Meier survival analysis showed that patients with RVSP > 55 mmHg and those with TAPSE/RVSP ratio < 0.42 mm/mmHg had a lower survival probability.
conclusionsTAPSE/RVSP < 0.42 mm/mmHg is a strong predictor of short-term mortality in patients with SMR when considered for valve surgery.
