Acute Hypertensive Heart Failure Due to Post-anesthetic Shivering After Mitral Valve Transcatheter Edge-to-Edge Repair: A Case Report.
Article in Cureus, 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
Post-anesthetic shivering (PAS) is common after general anesthesia and causes sympathetic excitement, followed by elevated blood pressure. Mitral valve transcatheter edge-to-edge repair (TEER) with MitraClip® (Abbott, Santa Clara, CA) increases left ventricular output resistance because of mitral valve narrowing. PAS after TEER synergistically raises cardiac load, surpassing the left ventricular working reserve and greatly increasing the risk of left ventricular failure in patients. A 64-year-old woman diagnosed with functional severe mitral regurgitation underwent implantation of MitraClip under general anesthesia and was subsequently transferred to the intensive care unit (ICU). Thirty minutes after admission to the ICU, the patient exhibited shivering, elevated blood pressure, and reduced oxygen saturation. There was no evidence of clip displacement, and the cause of this oxygenation impairment was considered to be hypertensive heart failure triggered by shivering. Noninvasive mechanical ventilation, antihypertensive medication, and body surface warming were initiated. The patient showed signs of recovery within two hours. Shivering can increase patient risk after TEER. Effective prevention of shivering is essential because TEER, along with shivering, can increase left ventricular ejection resistance, known as afterload mismatch.
