Device Embolization After Transcatheter Patent Foramen Ovale Closure: The Importance of Tunnel Width Assessment.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundPatent foramen ovale (PFO) is associated with cryptogenic stroke. Guidelines recommend PFO closure over medical therapy in patients aged 18 to 60. CASE SUMMARY: A 40-year-old woman underwent PFO closure at an outside institution, which was complicated by device embolization. Using three-dimensional (3D) transesophageal echocardiography (TEE) to assess PFO tunnel width revealed a larger PFO and guided closure with a 35-mm occlusion device instead of a 25-mm device. WHY BEYOND THE GUIDELINES: Manufacturer guidelines recommend PFO occlusion device sizing based on tunnel length, which resulted in inappropriate sizing. This report presents the use of PFO tunnel width for device sizing. DISCUSSION: This case report highlights the importance of 3D TEE assessment of PFO tunnel width and length to ensure successful percutaneous PFO closure. Reduction of stroke risk is predicated on eliminating right-to-left shunting. Device sizing based on tunnel width resulted in successful outcomes. TAKE-HOME MESSAGES: Percutaneous PFO closure is recommended over medical therapy for cryptogenic stroke in patients younger than 60 years. Appropriate closure device selection was enhanced with the use of multiplanar 3D TEE to assess PFO tunnel width.
