Short-Term Results on Leaflet Mobility in Patients Undergoing Rheumatic Mitral Valve Repair With an Efficient 4-Step Commissuroplasty Technique.

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
backgroundMitral valve stenosis (MS) is the primary pathologic feature of rheumatic mitral valve disease, and the complex repair affects its clinical outcome. This study aimed to examine the efficacy of the 4-step commisuroplasty "SCORe" procedure by assessing changes in the mobility of mitral valve leaflets and its clinical effects.
methodsFrom September 1, 2018, to January 13, 2019, patients with MS who underwent mitral valve repair with the SCORe procedure in the study center were analyzed in this prospective study. Mitral valve structure was assessed by transthoracic echocardiography pre- and postoperatively as well as during follow-up.
resultsIn total, 60 consecutive patients were examined. In 56 patients (93.3%), mitral valve orifice area (MVOA) was less than 1.5 cm2, and mean (SD) MVOA for the whole cohort was 1.20 (0.34) cm2. The mobility of the anterior leaflet was improved (P < .001) during the cardiac cycle postsurgery, but that of the posterior leaflet was not (P = .591). The mean (SD) coaptation length was increased significantly from 6.69 (1.32) mm to 7.92 (1.24) mm (P < .001) postoperatively. Mean (SD) MVOAs increased to 2.24 (0.38) cm2 postoperatively (P < .001). During the 1-year follow-up, there were no deaths or reoperations. Follow-up echocardiography revealed minor or mild regurgitation in 98.3% of patients.
conclusionThese findings demonstrated that the SCORe procedure can effectively improve the mobility of mitral leaflets and enlarge the valve orifice area in patients with rheumatic MS in China, with minimal complications and promising results.
