Acute Infarction Due to Extrinsic Coronary Compression by Left Ventricular Pseudoaneurysm Following Endocarditis Surgery-Case Management.

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
Extrinsic coronary compression is rare, difficult to diagnose, and can have serious consequences. A patient who had surgery for aortic valve endocarditis with patch closure of a septal abscess was readmitted for myocardial infarction. CT scan revealed compression of the left main stem due to pseudoaneurysm formation under the patch. Positron emission tomography confirmed acute hypoperfusion of the left ventricle, making immediate high-risk reoperation unavoidable. Imaging of the patient at one-year follow-up showed complete thrombosis of the former abscess cavity. Extrinsic coronary compression due to an abscess/pseudoaneurysm is associated with a high mortality rate and surgery appears to be the only possible life-saving treatment. In cases of unclear cardiac symptoms occurring under these circumstances (and thus suggesting extrinsic coronary compression), early imaging for quantitative myocardial perfusion should be considered to assess severity of myocardial ischaemia and thus urgency of surgery.
