Pulmonary Vein Stump: A Left Atrial Cardioembolic Source.
Article in JACC. Case reports, 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
backgroundThe left atrial appendage (LAA) is the most common nidus for thrombus formation in atrial arrythmias. CASE SUMMARY: We present a case of acute limb ischemia initially thought to be embolic due to LAA thrombus from atrial flutter. Transesophageal echocardiography before direct current cardioversion demonstrated a LAA without thrombus and favorable filling velocities. However, thrombus was discovered in the postsurgical pulmonary vein stump. DISCUSSION: Pulmonary vein stumps are becoming recognized as a common source of intracardiac thrombus after lobectomy. TAKE-HOME MESSAGE: Performing a comprehensive transesophageal echocardiography before direct current cardioversion is paramount to avoid missing thrombi outside the LAA, especially in at-risk populations.
