"False" False Tendon: Fatal Intramyocardial Dissecting Hematoma.
Article in Journal of medical cases, 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
Intramyocardial dissecting hematoma (IDH) is a rare complication that may emerge from myocardial infarction, thoracic injury, or percutaneous intervention. In the past, IDH was diagnosed through surgical intervention or postmortem autopsy. We present a case of a 70-year-old male with comorbidities who admitted to the intensive care unit after suffering out of hospital pulseless electrical activity cardiac arrest and obtained return of spontaneous circulation after chest compressions. Initial electrocardiogram (ECG) showed ST elevation in the anterolateral leads. Repeated ECG a few minutes later showed junctional rhythm bradycardia with a rate of 27 and serial changes of an anterolateral infarct were present and placed on percutaneous pacing with vasopressors. The troponin I peaked at 1.880. Transthoracic echocardiography (TTE) portrayed a hyperechoic mobile filamentous structure near the cardiac apex, which was thought to be a false left ventricular (LV) tendon initially. A repeat TTE with the use of an ultrasound enhancing agent (sulfur hexafluoride) revealed an apical neocavity with no contrast filling, suggestive of a large apical IDH within the LV. The patient expired because of cardiac arrest secondary to cardiogenic shock refractory to pressor support, with no autopsy performed. This case highlights an uncommon and timelier diagnostic modality of IDH in deference of more costly and prolonged imaging studies.
