Intramyocardial Hematoma After Percutaneous Coronary Intervention for Chronic Total Occlusion: Two Case Reports.
Article in Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) is an extremely challenging procedure, with intramyocardial hematoma (IMH) being one of its rare yet severe complications. In this report, we detail two cases of IMH occurring during PCI for CTO, emphasizing the importance of avoiding catheter pressure entrapment and high - dose antegrade angiography during recanalization. Both cases were the right coronary artery (RCA) CTO. In one case, after antegrade recanalization, the patient developed pericardial tamponade secondary to IMH due to these risky factors (catheter pressure entrapment and high-dose antegrade angiography), which necessitated surgical intervention. In the other case, following the same risky factors and repeated angiography, the patient experienced hypotension due to IMH, diagnosed by transthoracic echocardiography. However, as the hematoma did not involve the pericardium, conservative management was adopted.
