Antithrombotic Therapy in Percutaneous Atrial Structural Interventions.
Review in Journal of cardiovascular development and disease, 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
Percutaneous left atrial appendage occlusion (LAAO), patent foramen ovale (PFO) closure, and atrial septal defect (ASD) closure rely on temporary antithrombotic therapy to prevent device-related thrombus during endothelialization, yet optimal regimens remain uncertain and vary widely across clinical practice. This review synthesizes contemporary evidence on postprocedural antithrombotic strategies, comparing efficacy and safety data and identifying key gaps in knowledge. After LAAO, therapeutic approaches range from short-term anticoagulation with vitamin K antagonists or direct oral anticoagulants to dual or single antiplatelet therapy in patients with high bleeding risk; observational data increasingly support DOAC-based regimens, although device-related thrombus remains a significant concern, and follow-up imaging protocols are inconsistent. Following PFO and ASD closure, antiplatelet-only regimens-typically brief dual antiplatelet therapy followed by aspirin-are widely used, with evidence suggesting that simplified or abbreviated strategies may be sufficient in selected patients. Despite extensive clinical experience, high-quality comparative trials are limited, and optimal therapy, duration, and surveillance remain debated. Standardized imaging definitions, randomized studies, and individualized risk-based frameworks are needed to optimize antithrombotic care after atrial structural interventions.
