Life-Threatening Cardiac Compression Secondary to a Massive Hiatus Hernia With Gastric Volvulus: 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
Large hiatal hernias are typically managed conservatively; however, in rare instances, they can lead to life-threatening mechanical cardiovascular complications through direct extrinsic compression of the cardiac chambers rather than pericardial fluid accumulation, producing "functional" tamponade physiology. An 88-year-old man presented to the emergency department with sudden worsening of a three-day history of chest and upper abdominal pain radiating to the back. On arrival, he was vomiting, dyspneic, pale, and hypotensive (blood pressure: 96/52 mmHg). A CT angiogram revealed a massive hiatal hernia containing the stomach and transverse colon, complicated by gastric volvulus and anterior cardiac compression consistent with tamponade physiology. Nasogastric decompression was unsuccessful due to distorted anatomy. The patient subsequently underwent an urgent esophagogastroduodenoscopy (OGD) within one hour of CT acquisition, which aspirated 1.1 L of thick gastric contents, leading to the resolution of the cardiac compression. OGD was chosen over immediate surgical intervention due to the patient's frailty and comorbidities, with the aim of rapid decompression and minimizing the perioperative risk. He made a full recovery and was discharged shortly thereafter, remaining symptom-free at the three-month follow-up. This case highlights a rare but critical complication of massive hiatal hernia causing functional cardiac tamponade. Prompt recognition through CT imaging and timely endoscopic decompression can be life-saving.
