Overcoming NOAC-resistant left atrial appendage thrombus in atrial fibrillation: clinical gaps and therapeutic insights.
Review in Frontiers in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Atrial fibrillation (AF) is the most common supraventricular arrhythmia and a major cause of stroke and systemic embolism. The left arial appendage (LAA) is the predominant site of thrombus formation in AF. According to current guidelines, oral anticoagulant (OAC) therapy is recommended in patients with elevated thromboembolic risk. Non-vitamin K antagonist oral anticoagulants (NOACs) are currently preferred over Vitamin K antagonists (VKAs) due to favorable safety profiles. Nevertheless, a subset of patients develop LAA thrombi despite optimal anticoagulant therapy, a clinical scenario not addressed by current guidelines. Recent retrospective studies, including our own cohort analysis, suggest, that modifying antithrombotic regimen may improve thrombus resolution in these cases. However, no prospective trials have yet defined the optimal strategy. This mini-review summarizes the available evidence, highlights the limitations of current practice, and proposes directions for future research in this underrecognized clinical dilemma.
