Right Atrial Thrombus After Aspiration Thrombectomy for Pulmonary Embolism: Oh No or PFO?
Article in JACC. Case reports, 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
backgroundA 45-year-old woman with a history of pulmonary embolism, Sjogren syndrome, and hypertension presented with shortness of breath and palpitations. CASE SUMMARY: Computed tomography angiography of the chest showed nonocclusive, bilateral emboli in the main pulmonary arteries and segmental branches. Mechanical thrombectomy was performed, with transthoracic echocardiography revealing a right atrial thrombus within a patent foramen ovale (PFO). Transesophageal echocardiogram confirmed a 2.7 × 0.6 cm thrombus. Aspiration thrombectomy and patent foramen ovale closure with a Sentinel cerebral protection system (Boston Scientific) were performed, without residual thrombus. DISCUSSION: Aspiration thrombectomy with patent foramen ovale closure can be beneficial, but it requires embolic protection given the location within the tunnel. Early and aggressive management is critical in preventing serious embolic complications. TAKE-HOME MESSAGES: Multimodality imaging is essential for effective intervention, especially in patients with high procedural risk. This case underscores the importance of tailored strategies in complex cases involving atypical thrombus presentations.
