Mechanical Aortic Valve Thrombosis During Anticoagulation Using Oral Rivaroxaban: A Case Report.
Article in Cureus, 2024. 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
Direct oral anticoagulants (DOACs) are widely used in cardiovascular medicine. Although rivaroxaban has potential benefits for anticoagulation in certain contexts, DOACs remain contraindicated in patients with mechanical heart valves. This case report highlights the life-threatening risks of rivaroxaban use in patients with mechanical aortic valves, underscoring the lack of proven efficacy and the necessity of adhering to established anticoagulation protocols with warfarin for this patient population. Here, we report a case of a 65-year-old man who had previously undergone aortic valve replacement and developed a thrombus in the mechanical aortic valve six months after switching from warfarin to rivaroxaban. The patient experienced a sudden loss of consciousness and chest discomfort. Echocardiography revealed a thrombus in the valve requiring urgent reoperation and replacement with a bioprosthetic valve. The postoperative recovery was uneventful.
