Right Atrial Myxoma Presenting as Recurrent Ventricular Tachycardia: A Rare Clinical Presentation.
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
backgroundMyxomas are the most frequent primary cardiac tumors, with right atrial origin relatively uncommon. Clinical presentation varies with tumor size, mobility, and location. CASE SUMMARY: A 34-year-old male patient presented with recurring ventricular tachycardia. Echocardiography demonstrated a large stalked right atrial mass causing right-sided chamber dilatation and severe tricuspid regurgitation. Computed tomography confirmed a calcified right atrial mass. Surgical excision of the lesion along with tricuspid valve annuloplasty was subsequently performed. Histopathology confirmed atrial myxoma with calcification and osseous metaplasia. Postoperative course was uneventful with no arrhythmic complications. DISCUSSION: Right atrial myxomas may present unusually with ventricular arrhythmias. Calcification and osseous metaplasia are uncommon findings in cardiac myxomas. Early surgical resection remains the definitive treatment and confers excellent outcomes. TAKE-HOME MESSAGES: Right atrial myxoma can rarely present with recurrent ventricular tachycardia alongside structural and mechanical complications. Multimodality imaging-guided surgical excision is curative and prevents life-threatening complications.
