Intracranial Hemorrhage as a Marker for Mycotic Aneurysm in Patients With Infective Endocarditis.

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
Background and Objective: Mycotic aneurysms are a significant complication of IE that can lead to intracranial hemorrhage (ICH) and occasionally require intervention before valve surgery. Digital subtraction angiography (DSA) remains the gold standard for the detection of mycotic aneurysms but is an invasive procedure with contrasted dye exposure. Our objective was to determine predictive factors for the presence of mycotic aneurysms in patients with known infective endocarditis (IE). Methods: IRB exemption was obtained from the University of Pittsburgh Medical Center. Patients with left-sided or right-sided endocarditis with patent foramen ovale (PFO) were identified. Records were retrospectively reviewed by an independent investigator. Patients were stratified by demographic information, diagnostic imaging, and clinical outcomes. Standard descriptive statistics were used for characterization. The χ Results: 36 cases of left-sided or right-sided endocarditis with PFO undergoing evaluation for valve surgery were identified. Twenty-seven patients underwent CNS imaging, and 24 underwent DSA. Six patients were found to have ICH on CNS imaging. Mycotic aneurysms were identified by DSA in 5 patients (13.9%), and of these patients, 4 (80%) presented with ICH and 1 with ischemic stroke. Notably, the patient who presented with ischemic stroke then developed ICH on follow-up CT imaging. The negative predictive value of the absence of ICH on initial CNS imaging for the presence of mycotic aneurysm was 97.4%. Discussion: Patients with left-sided and right-sided endocarditis with PFO and ICH on CNS imaging were more likely to have mycotic aneurysms detected through DSA than similar patients without ICH. Routine DSA screening for mycotic aneurysms may not be required in patients with endocarditis undergoing evaluation for valve surgery who present without ICH on CNS imaging.
