Acute Left Ventricular Dysfunction After Mitral Transcatheter Edge-to-Edge Repair.
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 3 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
backgroundMitral transcatheter edge-to-edge repair (M-TEER) is an established treatment for severe mitral regurgitation. However, acute left ventricular (LV) dysfunction may complicate the procedure through mechanisms with distinct implications. CASE SUMMARY: An 81-year-old man with severe primary mitral regurgitation underwent elective M-TEER. Immediately after clip deployment, he developed acute LV dysfunction, initially managed as afterload mismatch (AM) with vasodilators. The clinical evolution was associated with apical ballooning on echocardiography, with electrocardiographic changes and troponin elevation without obstructive coronary disease, supporting Takotsubo syndrome (TTS). The patient remained stable, and LV function fully recovered within 1 week. DISCUSSION: This case illustrates the difficulty of distinguishing AM from TTS after M-TEER, 2 entities with overlapping features but different prognostic and therapeutic implications. TAKE-HOME MESSAGES: Acute LV dysfunction after M-TEER should not be automatically attributed to AM. TTS should be considered, and the integration of clinical, echocardiographic, and electrocardiographic findings is essential to management.
