Chylothorax Following Pulmonary Vein Isolation: A Case Report and Management Considerations.
Article in Journal of cardiovascular electrophysiology, 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
introductionChylothorax is a rare complication of thoracic procedures caused by leakage of chyle into the pleural space secondary to thoracic duct injury or obstruction. Although uncommon, it can lead to significant respiratory compromise and requires prompt recognition and management. METHODS AND
resultsWe report the case of a patient who developed progressive respiratory distress 2 days after undergoing pulmonary vein isolation with radiofrequency ablation. Imaging demonstrated large bilateral pleural effusions, which were identified as bilateral chylothoraces. The patient was managed conservatively with placement of bilateral thoracostomy tubes and initiation of a low-fat diet, resulting in successful resolution of symptoms and chyle leakage.
conclusionThis case represents an unprecedented presentation of bilateral chylothoraces following pulmonary vein isolation with radiofrequency ablation. Clinicians should maintain awareness of this rare but potentially serious complication in patients presenting with respiratory symptoms after ablation procedures, as early diagnosis and conservative management may result in favorable outcomes.
