TAVR in Rheumatic Aortic Stenosis With Mechanical Mitral Prosthesis: Case Series on Short Annulus-Prosthesis Distance.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Patients with rheumatic aortic stenosis and prior mechanical mitral valve replacement present unique challenges for transcatheter aortic valve replacement, particularly when the aortomitral distance is short. This case series examines 4 such patients, focusing on procedural complexities, imaging strategies, and outcomes. Preprocedural multidetector computed tomography and intraprocedural transesophageal echocardiography were critical in assessing anatomical constraints and optimizing valve deployment. Key considerations included preventing mitral prosthesis interference, mitigating left ventricular outflow tract obstruction, and ensuring stable valve positioning. One patient experienced mitral leaflet impingement, necessitating transcatheter heart valve repositioning. Despite these challenges, no transcatheter heart valve embolization occurred, and all patients had favorable clinical outcomes. This study highlights the importance of individualized procedural strategies, careful valve selection, and advanced imaging techniques in successfully navigating transcatheter aortic valve replacement in this complex subset of patients.
