Pregnancy Complicated by Severe Bioprosthetic Mitral Valve Stenosis Treated by Valve-in-Valve Transcatheter Mitral Valve Replacement.

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
The number of women with cardiac disease achieving pregnancy has increased and continues to rise. Traditional surgical cardiac interventions carry a high risk of morbidity and mortality for both mother and fetus during pregnancy. Transcatheter valve replacement is reserved for high-risk surgical candidates, but not widely used during pregnancy. Only 3 prior cases have been reported in which a transcatheter mitral valve replacement was done during pregnancy, all of which were performed before fetal viability. This paper presents the first reported case of a patient who had severe bioprosthetic mitral valve stenosis who underwent transcatheter mitral valve replacement via a valve-in-valve approach at 25 weeks' gestation with good maternal and fetal outcome. Transcatheter mitral valve replacement via a valve-in-valve approach may be a safer and effective alternative to surgical replacement when termination of pregnancy is not sought for severe bioprosthetic mitral valve stenosis.
