Successful Percutaneous Extraction of a WATCHMAN FLX Device From the Left Ventricular Outflow Tract.
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
backgroundAlthough rare, embolization of left atrial appendage occlusion (LAAO) devices carries a significant morbidity and mortality burden. CASE SUMMARY: An asymptomatic 77-year-old woman with inability to tolerate anticoagulation due to gastrointestinal bleeding presented for 45-day transesophageal echocardiography following LAAO with a Watchman device, which demonstrated incidental device migration to the left ventricular outflow tract (LVOT). Percutaneous extraction was performed using a novel technique with rat tooth/alligator forceps to successfully retrieve the Watchman from the LVOT using a transaortic approach. DISCUSSION: LAAO device embolization is a rare, yet serious, complication. Retrieval from the LVOT is typically performed with cardiac surgery to avoid damage to the mitral valve. This case demonstrates that percutaneous Watchman device retrieval from the LVOT is technically challenging but can be safely performed in select cases to decrease the length of hospitalization and morbidity associated with surgery.
