Diagnostic pitfalls in constrictive pericarditis coexisting with right ventricular outflow tract obstruction and coronary artery anomaly.
Article in Journal of surgical case reports, 2026. 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
Constrictive pericarditis associated with an anomalous left anterior descending artery is a very rare and complex condition. The aim of this report is to highlight the diagnostic challenges and surgical management in this disease. A 40-year-old man with right heart failure, dyspnea, and ascites, underwent comprehensive cardiac evaluation and surgery. The pulmonary valve was dysplastic, causing severe right ventricular outflow tract (RVOT) obstruction. During resection, the left anterior descending artery was inadvertently transected and bypassed with a saphenous vein graft. RVOT reconstruction, pulmonary valve replacement, and tricuspid valve repair were performed. Postoperative follow-up showed satisfactory ventricular and valve function; however, structural changes and reduced right ventricular function persisted. Non-invasive coronary imaging is necessary when angiography is not feasible, and the limitations of transesophageal echocardiography should be considered. Chronic right ventricular changes may not be fully reversible, emphasizing the need for long-term follow-up.
