Successful surgical treatment of a giant right ventricular myxoma with pulmonary artery tumor thrombus in an adolescent patient: case report.

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
Right ventricular myxoma (RVM) is a rare cardiac tumor. We report an uncommon case of RVM without Cushing's syndrome in an 18-year-old male who presented with chest tightness. Echocardiography revealed an abnormal echo-dense mass (7 cm × 6.5 cm × 4.9 cm) in the right ventricle, which was strongly suggestive of myxoma. Enhanced chest computed tomography (CT) demonstrated an irregularly enhancing mass (approximately 4.7 cm × 4.3 cm) attached to the ventricular wall and septum. A nodular filling defect (approximately 2.3 cm × 1.6 cm) in the right lower pulmonary artery trunk indicated a tumor-related embolism. Laboratory tests showed normal adrenocorticotropic hormone levels, with no clinical signs of Cushing's syndrome. On the second day after admission, the patient underwent successful surgical resection of the RVM, pulmonary artery myxoma thrombus, and tricuspid valvuloplasty. Postoperative recovery was uneventful, and the patient was discharged on postoperative day 11. This case highlights diagnostic and therapeutic strategies for this rare entity and offers clinical insights for similar presentations.
