Primary Aortitis: A Diagnostic Mimic of Intramural Hematoma Presenting With Complete Atrioventricular Block.

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
backgroundDifferential diagnosis between aortitis and intramural hematoma is challenging yet critical. Atypical presentations, including atrioventricular conduction disorders, should raise suspicion of aortitis. CASE SUMMARY: A 57-year-old man presented with dizziness, aortic regurgitation, and complete atrioventricular block. Computed tomography suggested intramural hematoma, whereas fluorine-18 fluorodeoxyglucose positron emission tomography-computed tomography proved pivotal for the differential diagnosis. Infectious and autoimmune workup was negative. Immunosuppressive therapy led to partial recovery of complete atrioventricular block, but permanent pacing was ultimately required. A diagnosis of primary aortitis was established. DISCUSSION: Aortitis can display atypical imaging features and may affect the conduction system. To our knowledge, this is the first reported case of primary aortitis presenting with complete atrioventricular block exhibiting conduction improvement after immunosuppressive therapy. TAKE-HOME MESSAGES: Primary aortitis can mimic intramural hematoma and present with complete atrioventricular block. Multimodal imaging is essential to achieve diagnostic accuracy. Immunosuppression may lead to conduction recovery.
