Residual Left Atrial Appendage After Incomplete Surgical Closure.
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
backgroundAnticoagulation reduces the risk of stroke in patients with atrial fibrillation, but not all patients can tolerate therapy. Although surgical left atrial appendage occlusion (LAAO) offers an alternative approach, incomplete left atrial appendage (LAA) closure can present management challenges. CASE SERIES SUMMARY: We present 2 cases of residual LAA after surgical LAAO. In one case, an 81-year-old man with prior AtriClip developed anemia and subclinical bleeding, precluding long-term oral anticoagulation. Incomplete surgical LAA closure was confirmed on computed tomography, and he was successfully treated with transcatheter LAAO. In the second case, an 84-year-old woman with prior AtriClip and history of intracerebral hemorrhage presented after an acute ischemic stroke. Her high bleeding risk and residual LAA anatomy precluded both standard-dose therapeutic anticoagulation and transcatheter intervention. DISCUSSION: Incomplete surgical LAA closure presents unique management challenges. Both transcatheter and medical management have roles, depending on individual patient anatomy and comorbidities. Careful follow-up imaging is crucial for identifying residual LAA patency after surgical occlusion.
