Conservative Management for Left Atrial Intramural Hematoma After Cryoballoon Ablation.
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
backgroundLeft atrial intramural hematoma (LAIH) is an extremely rare complication associated with left atrial procedures. CASE SUMMARY: We report the case of a 50-year-old man who developed LAIH during cryoballoon ablation for paroxysmal atrial fibrillation. The lesion was detected immediately after the procedure by routine intracardiac echocardiography, enabling prompt management. Because the patient remained hemodynamically stable, conservative management with bed rest and close monitoring was chosen. The hematoma showed gradual regression, and the patient was discharged on postoperative day 13 without secondary complications. DISCUSSION: Although surgical intervention is often required in hemodynamically unstable patients, this case demonstrated that conservative management can be an effective strategy for hemodynamically stable patients with LAIH. TAKE-HOME MESSAGES: LAIH can be successfully managed with conservative treatment in hemodynamically stable patients. Early recognition and timely intervention are essential for complete resolution.
