Two Cases of Arrhythmic Mitral Valve Prolapse: Evil Has Many Faces.

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
Mitral valve prolapse (MVP) is one of the most common valvular heart diseases. Although MVP is generally considered benign, it can be associated with important complications, including sudden cardiac death (SCD), owing to ventricular arrhythmias (VAs). Several clinical, electrocardiographic, and imaging findings have been associated with MVP-related SCD, including female sex, T-wave inversions in the inferior leads, complex ventricular ectopy, leaflet redundancy (classic MVP), mitral annular disjunction, pickelhaube sign (a spiked configuration of the lateral annular velocities), and evidence of myocardial fibrosis in cardiac magnetic resonance (CMR) imaging. However, neither of these markers, nor any specific combination of them, have proved to be a consistent predictor of malignant VAs and SCD. In this context, we present 2 interesting cases of arrhythmic MVP, highlighting the broad clinical spectrum of this condition, the potential underlying arrhythmogenic mechanisms, and the merit of identifying patients at high arrhythmic risk.
