Thirty-Year Prevalence of Spontaneous Hemoptysis in Palliated Single Ventricle Circulation.
Article in Journal of the American Heart Association, 2025. 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
backgroundSpontaneous hemoptysis is a well-recognized risk of palliated single ventricle circulation, yet published literature is limited to case reports and small case series. In this study, we sought to determine the long-term prevalence of spontaneous hemoptysis among patients with palliated single ventricle circulation at a single institution. Secondarily, we sought to characterize the clinical outcomes after spontaneous hemoptysis.
methodsWe conducted a retrospective study of patients with a history of Glenn or Fontan palliation seen from January 1, 1990 to January 21, 2023. Episodes of spontaneous hemoptysis were identified through 2 independent database screens that queried
resultsOf 799 patients with palliated single ventricle circulation, 10.9% (87/799) screened positive for hemoptysis. Following verification with manual chart review, 3.4% (27/799) of patients with palliated single ventricle circulation had spontaneous hemoptysis. A total of 61 episodes of spontaneous hemoptysis occurred in 27 patients. Of all hemoptysis episodes, 83.6% (51/61) occurred after Fontan palliation. Of patients with hemoptysis, 51.9% (14/27) had multiple episodes of hemoptysis with recurrence at a median of 0.6 years (range 1 day-8.5 years) after the first episode.
conclusionsTo our knowledge, this is the first study that quantifies prevalence of hemoptysis in a large cohort of patients with palliated single ventricle circulation. Overall, prevalence of spontaneous hemoptysis was low (3.4%) among patients with palliated single ventricle circulation and there was a moderate rate of recurrence (51.9%).
