Case Report: Intracardiac echocardiography-guided pulmonary vein stenting for pulmonary vein stenosis caused by a left atrial tumor.

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: Pulmonary vein stenosis (PVS) caused by a cardiac tumor is rare, and experience with transcatheter pulmonary vein stenting is limited. We report a challenging case of symptomatic PVS managed with intracardiac echocardiography (ICE)-guided pulmonary vein stenting as palliative treatment. Case: An 83-year-old woman presented with progressive dyspnea for 4 months. Electrocardiography, chest x-ray, and routine laboratory tests were unremarkable. Transthoracic echocardiography revealed a large left atrial mass involving the right pulmonary vein and causing stenosis. Multimodality imaging, including cardiac computed tomography (CT), cardiac magnetic resonance imaging, and Conclusion: In selected patients with PVS who are unsuitable for surgical treatment, ICE-guided pulmonary vein stenting can be performed safely and may provide effective palliation by restoring pulmonary venous flow and relieving symptoms.
