The Constricted Heart: A 31-Year-Old Man with a Case of Constrictive Tuberculous Pericarditis.

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
BACKGROUND Constrictive pericarditis occurs due to chronic pericardial inflammation and adherence of the cardiac pericardial layer. Etiologies include toxins, infection, cardiac surgery, and idiopathic causes. Outside the United States, the most common cause of constrictive pericarditis is tuberculosis (TB). Constrictive pericarditis is the most severe complication of tuberculous pericardial disease. CASE REPORT A 31-year-old man who recently immigrated to the United States presented with a 2-week history of constitutional symptoms, dyspnea, and pleuritic chest pain. Physical examination was pertinent for bilateral lower extremity pitting edema, decreased bilateral breath sounds, and jugular venous distension. Transthoracic echocardiogram revealed a left ventricular ejection fraction of 45%, pericardial thickening, and an exaggerated septal bounce. Right heart catheterization showed discordant and concordant right ventricular pressure tracings. Cardiac magnetic resonance imaging revealed bilateral pleural effusions and circumferential pericardial thickening. Thoracocentesis was significant for an exudative effusion, with elevated adenosine deaminase levels. Subsequent QuantiFERON-TB Gold testing was positive, and he underwent elective pericardiectomy. Pericardial histopathology revealed necrotizing caseating granulomas. He was discharged on a 6-month course of rifampicin, isoniazid, pyrazinamide, and ethambutol therapy, with close multidisciplinary care team outpatient follow-up. CONCLUSIONS This case highlights the importance of a high index of clinical suspicion for tuberculous pericarditis in patients presenting with constitutional and heart failure symptoms and a relevant travel history, to ensure prompt diagnosis and treatment. This case also reflects the importance of coordination of care between cardiology, infectious disease, pathology, and cardiothoracic surgery teams in the management of tuberculous constrictive pericarditis.
