Congenital descending aorta to pulmonary vein fistula: an unusual cause of left ventricular dilation in a 21-year-old female.
Article in Journal of cardiothoracic surgery, 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
backgroundCongenital descending aorta to pulmonary vein fistula (cDAPVF) is a rare congenital vascular malformation diagnosed in infancy and childhood. Adult cDAPVF is often asymptomatic and usually detected incidentally by imaging. At present, cases of adults with an enlarged left heart due to cDAPVF have rarely been reported. CASE PRESENTATION: We reported a case of 21-year-old female who presented with an unexplained continuousmurmur and left ventricular enlargement followed up for 6 years. The patient developed chest tightness five days ago. The patient was diagnosed with cDAPVF, as revealed by echocardiography combined with computed tomography angiography (CTA). The patient underwent arteriovenous embolization, with satisfactory improvement in symptoms and left ventricular size during follow-up examinations.
conclusionscDAPVF should be considered in patients with unexplainable left ventricular continuous murmur. CTA serves as a valuable adjunct for diagnosing abnormal vascular connections that cannot be identified by Doppler echocardiography. Transcatheter embolization may be an effective treatment for cDAPVF.
