Coronary Button Pseudoaneurysm Resolution After Aortic Root Replacement Upon Cessation of Anticoagulation.
Article in JACC. Case reports, 2026. 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
backgroundAnticoagulation after aortic surgery is associated with an elevated risk of pseudoaneurysm formation. CASE SUMMARY: We present an unusual case of a patient who, after a Bentall procedure, developed a right coronary button pseudoaneurysm after commencement of anticoagulation. After cessation of anticoagulation, serial computed tomography demonstrated complete resolution of this pseudoaneurysm, negating the need for reoperation. DISCUSSION: This case adds to the scant literature describing spontaneous resolution of post-Bentall pseudoaneurysms, particularly those involving the coronary buttons. To date, most reports emphasize percutaneous or surgical repair, and as such, data on benign courses under conservative management are sparse. TAKE-HOME MESSAGES: Anticoagulation may initiate and propagate early coronary button pseudoaneurysms after aortic root surgery. Not all pseudoaneurysms after aortic root surgery need to be treated with procedural intervention. Nonoperative management with computed tomography surveillance, cessation of anticoagulation, and strict blood pressure management should be considered for treatment of pseudoaneurysms.
